What to do if a tooth ache under the filling

Toothache for many is just hell, and so want to quickly get rid of it. Dentist in this case seems to us the only salvation. He will help to say goodbye to this problem once and for all. However, it is often the case that patients leave the dentist with almost the same pain. Naturally, such people are very interested in why a tooth aches after filling.

It is known that in the mouth we have the most sensitive nerve endings, and the process of filling, the elimination of infected and dead tissues is an additional injury to which the body responds with a natural reaction.

Sealing process

There are several reasons for the occurrence of discomfort, and the most obvious of them is the body's response to surgery, as well as improper installation of a seal, not fully cured caries or non-compliance with the doctor’s instructions. If, within 10-12 days after filling, the pain does not stop, you need to go to the doctor and determine the cause.

Seals are usually placed to treat tooth decay, which destroys a tooth. The process of sealing is not the most pleasant procedure, but it is the most optimal solution to the problem. An anesthetic is administered to the patient, then the affected tooth is opened and the damaged tissue is removed. After that, the actual filling, grinding and the final stage - polishing.

What is the pain?

In severe, advanced cases, it may be necessary to completely clean out the carious cavity, and sometimes nerve removal. All work is divided into several stages, and if a dentist makes a mistake on one of them, the pain cannot be avoided.

When discomfort occurs:

  • when chewing and biting, ingestion of cold or hot food,
  • in a calm state.

That is, the pain can be arbitrary or provoked by some factors from the outside. There are three main reasons why a tooth aches after filling:

  • The first is the body's natural reaction to the installation.
  • The second is the mistake of the doctor.
  • Third - the failure of the recommendations of the dentist.

Why does a tooth hurt after sealing: causes

Incorrect diagnosis. Pulpitis is easily confused with chronic caries, and an inexperienced doctor can make a mistake by putting a seal in the wrong place. Another situation - depressurization occurs, the material moves away from the bottom of the cavity, thereby irritating the nerve endings and delivering severe discomfort to the patient.

Dental polymerizers have a negative effect on the oral cavity and on the pulp, changing its structure, and this is another reason why a tooth ache after filling. The cavity of the tooth before installation should be prepared, namely - evenly dried. Overdrying leads to irritation of the nerve endings, which is why malaise appears. Incorrectly built-in filling will interfere and cause pain when biting.

An allergic reaction to composite materials or drugs may occur. In this case, the pain appears immediately after sealing. The nearby soft tissues swell, the gums, jaw and even the head are very sore.

Wines doctor

Often, the patient's own stamotologist is to blame for the patient's suffering, who, deciding to save, used cheap materials or, due to negligence, installed the seal incorrectly. An unpleasant throbbing, alternating with acute pain, occurs when the dentist hurried to cement the canal and installed a seal on the day of the patient’s first visit.

Why does the tooth hurt after filling? The nerve was not removed completely, but it must be removed radically. If infected nerve tissues remain, pus will collect under the filling, an inflammatory process will develop, which, as a rule, is accompanied by an increase in temperature. If improperly installed, the composite material can go beyond the limits of the dental root and irritate soft tissues, causing inflammation.

The emergence of a filling material outside the boundaries of solid tissue inside the gum can also cause inflammation. Why does the tooth hurt after filling? This is the body's reaction to infection.

The causes of the formation of pathogenic microflora

If you look at the structure of the tooth and root canals, you can see several conical small tubes. But the scheme does not give a complete picture, and the exact number of such branches cannot be seen before the start of treatment. It is impossible to process and fill up all branches qualitatively.

Therefore, if they remain in the original state after treatment, the inflammation does not go anywhere and persists, causing a toothache. Even a highly qualified specialist can not control the lumen of the channel throughout its length. Here are just a few factors that cause inflammation:

  • not completely cleaned infected canal walls,
  • walls of root canals badly washed from blood,
  • the appearance of pores when installing a seal,
  • resorption of composite material after installation.

The list of treatment defects leading to the accumulation of pathogenic microflora does not end there.

When pain is the norm

Not every pain can be a signal that you need to run to a dentist immediately. First of all, it is necessary to determine its character. If the question arises as to why a tooth ache after filling with pressure, this may be due to local irritation of tissues located close to it. Often the doctor, working with metal tools, damages the gums and root system. In this case, the pain should go away by itself.

When the seal was put on a tooth that was already disturbing, the discomfort will continue for some time. It is important at this time not to provoke pain by consuming hot or cold food and drinks.

Strengthen pain can:

  • too sweet food
  • additional load on the tooth,
  • eating solid foods
  • hypothermia

In non-compliance with these recommendations often lies the answer to the question of why a tooth aches after sealing a child. Children need to be monitored very carefully during rehabilitation.

First aid

When the pain does not go away within two weeks, this is a clear reason not to delay the return visit to the dentist. It is not always possible to see a doctor right away, and toothache can not be tolerated. There are already two questions: "Why does the tooth ache after filling? What should I do before going to the clinic?"

The first thing you can do is take painkillers. In such cases, drugs based on ibuprofen or paracetamol are recommended. Alcohol propolis tincture, from which tooth lotions are made, will help soothe the inflammation. It is used for rinsing the mouth.

  • Effectively help to eliminate discomfort decoctions of sage, chamomile, celandine, oak bark, acupressure, crushed beetroot porridge, compresses of fir oil.
  • The proven remedy will help to remove the edema - rinsing the mouth cavity with soda-salt solution (0.5 tablespoons each. L. Salt and soda dissolve in a glass of warm water).

However, it should immediately be said that it is impossible to completely solve the problem only with home remedies. Why does the tooth hurt after canal filling? Reviews of the effectiveness of folk remedies are positive, and their use will help soothe the pain, but not cure the tooth.

Swelling and swelling

The gums may swell severely after filling. In some cases, this is a normal phenomenon, in others - a signal of the beginning of a serious infection process. Redness, swelling, temperature - these are the first signs that purulent inflammation develops. If in this case you do not see a doctor, the situation can be fatal. The fact is that the pus accumulating in the gum does not independently leave and does not dissolve, it is looking for a way out.

Not finding him, the infection spreads through the bloodstream, reaching the maxillary sinuses, and then goes to the brain. Therefore, it is necessary to make a surgical incision in a timely manner and allow pus to come out.

Choosing a specialist

Dental treatment, including filling, it is important to trust only specialists who approach the problem solving responsibly and reduce the risk of sensations that disturb the patient. Normally, the pain passes through the week, although some doctors admit a longer period, it all depends on the degree of tooth decay.

The effectiveness of treatment is largely determined by the quality of the materials used, the instruments, and also the qualifications of the doctor, that is, the observance of all technologies. Careless attitude specialist may lead to:

  • flux and edema,
  • infectious infection
  • reaction to temperature changes
  • loss of a seal,
  • allergic reaction.

Often people are afraid to go to dentists not only because of the fear of pain, but also because of the high cost of services. An experienced specialist may provide services at inflated prices, but if he has established himself well, it is better to overpay once, than to suffer and spend even more.

Diagnosis of periodontitis

If caries reappears on the sealed tooth, it is necessary to treat the carious cavity with special solutions and insert a new filling. In any case, re-examination by a doctor is required, even in the absence of other symptoms.

With periodontitis, pain may occur after sealing. The doctor in this situation is not to blame. No one can guarantee the successful outcome of periodontitis treatment and will not immediately determine why a tooth aches after filling the canals. In this procedure, the movement of microbes is stopped, but their part remains sealed under the seal for as long as the body can not cope with them independently.

Possible reasons

Toothache under the filling can be both infectious and traumatic in nature, that is, it usually arises either due to penetration of bacteria into the sensitive soft tissues that cause inflammation, or due to some mechanical effect. In general, the tooth itself can not hurt, because it consists of bone tissue, which by definition is not sensitive to pain. However, pulp tissue in its cavity contains a large number of nerve endings, giving a signal to the brain about the presence of problems in the damaged area. That is why it so often happens that even a treated tooth aches under a filling.

When pathogenic bacteria enter the pulp, it begins to inflame and cause severe pain. If you have already come to the dentist for the treatment of a diseased tooth, then repeated pain may occur for the following reasons:

  1. With insufficient thorough cleaning of the site damaged by caries or with the installation of a leaky seal, a repeated carious process may develop, which, due to favorable conditions, will progress much faster. Typically, such missteps do not happen when referring to a good specialist from a proven clinic. So if after treatment you have been suffering from severe pain for a long time, especially if it is a seal on the front tooth, you should immediately sign up for a second appointment. In advanced cases, the tooth will have to be removed. The seal on the front teeth should be installed with great care and accuracy!
  2. Sometimes it happens that deep caries has already managed to damage the dentin layer under the enamel, and the infection has gone further onto the soft tissues, however, the strong pain has not yet begun. The doctor removes the damaged area of ​​enamel, seals the cavity. You return home, the anesthesia stops its effect and, perhaps immediately, and possibly a few days later, you understand that your tooth hurts very much under the filling. This means that the inflammatory process in the pulp has already reached the nerve endings, i.e. you started pulping.
  3. There is another situation. Suppose a doctor cured a neglected form of pulpitis, but the inflammatory process has already moved to a deeper level and has got through the apical opening in the root to the periodontal area. Thus, if you have a toothache under the filling, and the nerve is removed, there is a possibility of periodontitis.
  4. Another very unpleasant consequence of neglected forms of inflammation is a cyst. Most often, it grows for months, or even years, completely painlessly, while destroying the bony tissues of the jaw so much so that they can no longer be restored without resorting to surgery. So if you have a toothache after the filling, do not postpone the visit to the dentist for later, because it can turn out to be very deplorable consequences.
  5. An allergic reaction to the components of the filling substance is not uncommon today. Nowadays, more and more new drugs appear that can shorten the patient’s treatment to a minimum, but some of them contain potent components that can cause irritation, including. If suddenly, after one or two days after the treatment, a tooth ached under the filling, it is possible that the intolerance of any substance is to blame for everything. Often this pain is accompanied by other symptoms that can diagnose an allergic reaction.
  6. Does the tooth under the filling react to cold, hot, and pressing with aching pain? Possible causes: shrinkage due to the use of poor-quality material or left unsealed cavities, as well as the release of filling material into the periodontium through the apical opening. In order to avoid such a situation, it is recommended to apply only to proven dentistry, which has an X-ray machine.
  7. No one is immune from mistakes, so that even the best dentist can get into trouble. Often, to clean the canals of the tooth from the remnants of the pulp have a very thin instruments. If the tooth aches after sealing, a small piece of needle tip or drill left inside can be a possible cause. X-ray will allow you to exclude such a probability.
  8. Well, of course, non-compliance with the recommendations of the doctor, as well as the rules of hygiene, can lead to painful sensations.

To eliminate the causes of pain, you must always contact your doctor. And the sooner you do this, the less likely the development of complications.

If you have a toothache after installing a seal due to caries or pulpitis, the treatment will consist in drilling out the old composite, completely cleaning and disinfecting the damaged cavity and re-filling it.

With periodontitis, the treatment will be longer, since repeated treatment of the inflamed tooth and gum tissues with antiseptic preparations is necessary. Treatment of a cyst involves exclusively surgical intervention. Recently, many clinics have begun to use a laser device for this purpose, which makes the procedure virtually painless.

In case of an allergic reaction, the only treatment will be the replacement of the filling substance with another that does not harm the body. In all other cases, only the doctor who performed the initial treatment will be able to determine why a tooth ache after the filling and how to deal with it. From your side, you need only an immediate response to the problem and an appointment to a specialist.

The emergence of pain after the imposition of permanent fillings on a live tooth

A tooth after filling can hurt for various reasons. But the most frequent of them and the most dangerous is making a wrong diagnosis. Very often, doctors confuse the symptoms of deep caries with a chronic course of pulpitis or periodontitis. At the first diagnosis, a thin wall remains between the pulp and the carious cavity. Complaints are basically similar. And therefore, hoping that the tooth will remain alive, the treatment is performed as if with deep caries. After some time, or maybe even that night, there are strong spontaneous shooting pains. Why did they appear after installing the seal? After all, before that, the tooth did not bother. When the nerve is inflamed, it swells a little. If the cavity is open, it may not be felt. But in this case, the tooth is closed and pain arises under the pressure of the filling.

The second most frequent case is the overheating of hard dental tissues during preparation, that is, the mechanical processing of the carious cavity. It is produced turbine drill, which has a large number of revolutions per second. If you do not use air-water cooling and do not take periodic breaks, it leads to heating of the tissues. The nerve reacts to this rise in temperature. Usually in such cases, whining tooth after filling. It may bother a few days. If the nerve does not inflame because of this impact, then the pain after tooth fillings will pass by itself.

Sometimes painful discomfort may develop gradually, that is, the patient does not immediately understand that he is worried about the newly cured tooth. There are aching pains, especially when biting. This is due to the fact that the set filling is overestimated. That is, it is higher than the rest of the chewing surfaces, this tooth closes with the opposite one more quickly, at a time when they must close together at the same time. The patient in the chair cannot feel this, in view of the fact that the effect of the anesthesia has not yet ended, or if there was an extensive cavity, he could get used to the fact that there is emptiness and it is not immediately clear whether this is normal or not. Из-за этого возникает большая нагрузка на зуб и появляется дискомфорт. К тому же, это может привести к нарушению прикуса.

Последний этиологический фактор – это полимеризационный стресс. Modern dentists use only light fillings. It is very rare to find a place where chemical curing materials are put. Some fillings are larger when installed. Under the influence of an ultraviolet lamp, they shrink as they solidify. There is pressure on the dental walls and there are aching pain. How much a tooth hurts after sealing in this situation, no one knows. This may take a couple of weeks. And it may not even go through.

Why do teeth ache after nerve removal?

It would seem that the nerve is removed, there is nothing to hurt. But nevertheless there are pain. Why Do teeth hurt after canal filling? Normally, they can be observed. Pain will occur when biting this tooth, wearing a aching character, reacting to tapping, even to temperature stimuli. This is due to the fact that when the nerve is removed from the canals, it seems to come off from the larger nerve. And until this place of separation is healed, these discomfort will be disturbing. Such symptoms bother mostly for a maximum of a week.

If the toothache after filling canals lasts longer or the intensity increases every day, you should immediately contact your doctor. Because, the cause may be something else that requires appropriate treatment.

There can be several reasons:

  • The development of infection in the periphery tissues,
  • The nerve from the canal was not completely removed,
  • Tool breakage in the channel during its machining,
  • Incomplete obturation of root canals,
  • Perforation.

It is worth analyzing in more detail every reason.

Nerve stayed in the canal

To remove the nerve from the canal you need a tool such as pulpoextractor. He looks like a herringbone, his carving seizes the nerve. You need to enter the channel, twist once and pull out. If the nerve is alive, it is enough once. If necessary, repeat several times. But often it is twisted in the channel several times in different directions, which leads to incomplete removal. It also happens that the root canal is not completely passed. And at the end of the root, if the canal is narrow, a piece of nerve may remain. The doctor, not knowing about it seals channels. And then the tooth aches after filling the canals. In this case, the pain of the tooth after filling can slowly fade away, but there is a danger of periodontitis. Moreover, if you leave a tooth like that, it will darken over time, acquiring a gray-black color.

It may also happen that not just a piece was left, but the whole channel was not processed. The teeth do not have a certain number of roots and channels. This number can vary from two to six. Of course, three are more common in large indigenous ones. And many doctors make a mistake, relying on this figure. Found three channels, all the further you can stop. And it may happen that there is one or more channels. This will be regarded as an incorrect treatment, the doctor will have to re-heal this tooth.

Channel tool breakage

The reason why a tooth ache after filling the canals can be a very gross mistake of the doctor. Each person has a different structure of teeth, channels, their location. Someone they are well traveled, someone too narrow that it is impossible to pass the smallest tool. Some experts seeking to expand the walls as much as possible can break off the tool in one awkward movement and leave a piece there. In most cases, it cannot be removed from there. You can not leave, because this site will remain untreated and this can lead to serious consequences. In such cases, you have to remove the tooth. Incomplete obturation, that is, filling the entire canal, will also lead to inflammatory processes.

Inflammation at the top of the root

This process is called periodontitis. It arises due to the ingress of bacteria into the circumferential region, as a result of which pus is formed there. Most often, this process develops when the nerve is already decaying. But there are cases when periodontitis occurs with live nerves. Some doctors think that it is pulpitis and is treated appropriately, without eliminating inflammation outside the root opening. In this case, the tooth hurts after filling the canals intensely. Every day the throbbing pain in the tooth increases even more, due to the fact that the resulting pus has nowhere to go. The tooth is pulsing.
Can the pain go by itself? It is unlikely that it may become smaller, but in this case there is a risk of fistula on the mucous membrane in the projection of the inflamed root. Periodontitis can also develop with insufficient channel processing. Infected dentin shavings remain, which lead to the development of infection.

Perforation of the bottom of the tooth or the wall of the root canal

In other words, it is the creation of a hole in the tooth, which should not be. The bottom is often perforated when looking for the mouth of the canals. Unfortunately, there is no definite topography, but there are some guidelines. Many doctors may not know about it and drill through a tooth. Or, if the tooth is badly damaged due to the soft bottom, it can be mistakenly assumed that a canal has been found. And actually punctured the bottom. And the channels are pierced, trying to go through them. It happens that at the end they are severely twisted or sclerotic. And a specialist trying to open it to the end can make a hole in the wall of the channel.

There is still such a mistake as removing material beyond the top. The channel must be sealed to the physiological tip. If its opening is too wide, then there is a chance of removing the filling material. It can put pressure on the nerve endings, causing pain. With periodontitis, it is specially removed for the top. But only in chronic forms, when bone resorption occurs around the apex. In other cases, you must try to remove excess.

What measures to take with pain

What to do if teeth hurt after filling? If he is alive, he should return to his doctor and tell about his complaints. And in those cases when the pain arose after the filling of the tooth canals, it is necessary to observe it. That same day, he can start whining. This may be due to the fact that the filling material is removed or for many other reasons.

If the pain decreases with time, then there is nothing to worry about. To alleviate these pains, rinsing with anti-inflammatory solutions can be done.

When the tooth hurts badly, it starts to throb, you need to go to the doctor, having an x-ray with you. After the doctor determines why the tooth started to hurt after filling the canals, he will perform the appropriate manipulations. Pulsation occurs with periodontitis, most often, and in this case the specialist will unseal the canals and prescribe treatment and rinsing. The channels should be open until the pain completely disappears. How much a tooth can hurt depends on the degree of inflammation. The same applies to other reasons - you need to unzip and re-treat, now qualitatively under x-ray control.

Why does a sealed tooth hurt

The actions of the dentist during the treatment activities should be clearly organized. Any mistake when filling can lead to the accession of a secondary infection. This situation occurs if the doctor does not sufficiently process the carious cavity, which results in the formation of an infectious focus under the material filling it. In this regard, pulpitis and periodontitis are difficult to treat: the dentist often has to resort to the refilling. The main reasons why a tooth aches after a dental procedure are:

  • undertreated caries,
  • chronic pulpitis,
  • inadequate oral hygiene with sealed teeth,
  • incorrectly performed procedure of "drying" the inner walls of the tooth,
  • allergic reactions to the original material of the filling mass,
  • incomplete therapy of inflammatory gum tissue in periodontitis,

Incomplete removal of the pulp together with poor-quality filling of the dental canals may lead to the development of the inflammatory process in the deep periodontal tissues. This complication of endodontic therapy requires repeated medical intervention. However, only a specialist after carrying out the necessary diagnostic measures can answer exactly the question of why a tooth aches after filling. However, some indirect symptoms may indicate that things are not the best:

  • severe, throbbing or aching pain in the area of ​​the newly cured tooth,
  • swelling of adjacent tissues,
  • difficulty chewing and swallowing after tooth filling,
  • fever,
  • bad breath.

A tooth hurts after a canal filling

The development of events in this scenario requires the patient to be vigilant with respect to his health. In the closed space of the diseased tooth, the infection spreads with great speed. The danger is that purulent damage to bone or muscle tissue can occur. This pathology is treated with medication in the hospital. The situation may face even more serious consequences, in case of suspicion or the occurrence of which emergency emergency resolution of the problem is carried out to patients.

Toothache with pressure

Doctors are unanimous in the fact that painful sensations in the first time after a seal is placed are an absolutely normal post-filling phenomenon. Often, patients turn to the dentist with complaints of discomfort when pressing, pressing, biting, eating hot or cold. If a tooth aches after filling, then just try to “bypass” these provoking factors. Such conditions are not considered pathological and are considered as consequences of endodontic intervention in the form of damaged nerve endings.

How much can a tooth hurt after filling

Discomfort in the oral cavity can disturb the patient for a month after the procedure, which is explained by the "addiction" to the new tooth. If you are interested in how much a tooth aches after filling, then it is safe to say that this is a temporary phenomenon. A depulped osseous osteoporosis is usually not a major concern for patients. If such a tooth is suddenly sore, it will be regarded as a bright symptom of attaching a secondary infection with its spread to nearby tissues.

What to do if a tooth ache under the filling

Prevention of the disease consists in the exact execution of medical recommendations. If you have been warned about a possible pain syndrome after filling, then do not worry. You need to start with the removal of food debris from the tooth, after which you can rinse your mouth with warm soda or saline. In case of severe pain, it is recommended to take an anesthetic. However, you should not grab the pills each time, if the syndrome continues for a long time after filling. Such a state needs an assessment of its future prospects by a specialist.

Taking pain pills

Today, the pharmacy network offers the consumer a huge range of drugs, many of which have a large number of side effects. This fact should be taken into account in patients with gastrointestinal diseases, cardiovascular pathologies. It is worth noting that you should not get involved in taking dosage forms, even the most “harmless” ones. Responding to pain in the tooth after sealing should be timely and deliberately. To remove obsessive syndrome, you can use the following medicines:

Recipes of traditional medicine

The main advantage of alternative treatment methods is the almost complete absence of side effects. Rinsing with herbal teas, soda and saline solutions can be used by any age group of the population if a tooth aches. However, before starting the practical application of any recipe, it is strongly recommended to check the components of the product for allergenicity. In case a tooth aches badly after the filling procedure, you can use the following tips:

  1. Juice celandine. Apply freshly prepared product to the gum area several times a day. Pain syndrome usually goes away after 20-30 minutes.
  2. Appliques with onions and garlic. Fresh raw materials to bring to the state of gruel, after which it can be put in the form of an application on a sore tooth 3 times a day, covered with a cotton swab on top.
  3. Rinse with hydrogen peroxide. The solution is prepared from a proportion of 15 drops of peroxide per quarter cup of water. It is recommended to irrigate the mouth after each meal.

Dentist visit

In a situation where the pain does not go away for a long time, and the patient experiences constant discomfort, you need to seek help from a specialist. Often, several complaints that it hurts to press or bite enough to identify the "cause of all ills." This is usually followed by the removal of the filling, the reprocessing of the carious cavity, followed by the installation of a new filling on the already “dead” pre-pulped tooth.

Why the tooth can hurt under the filling

Pain in a filled tooth can be observed in the following typical cases:

  • after caries treatment (under permanent filling),
  • after canal treatment (under temporary or permanent filling).

First, we consider in detail why pain may be felt after treating caries and staging the fillings.

Dentists-therapists are always optimistic for the most part, as they strive to preserve a “live” tooth for any kind of caries, that is, without removing the pulp (“nerve”) from the canals. However, in some cases, at the stage of diagnosis and treatment, errors occur, which are associated to a greater extent with the tactics and approach of the doctor.

The most common errors that cause pain in a filled tooth are the following:

  1. Incorrectly diagnosed. This mistake is the absolute fault of the doctor. Deep caries and chronic forms of pulpitis are similar in symptoms and some external signs, so the dentist has a huge responsibility - not to confuse one with another. If an error nevertheless occurred, and the filling is superimposed during chronic pulpitis (as well as with other forms of pulpitis and periodontitis), then after its installation the tooth can ache “long and hard”. Without canal treatment in this case, the sealed tooth will not stop hurting, and moreover, every day the pain of patience is the risk of losing the tooth forever.
  2. Overheating of the tooth. This problem is still relevant in many clinics (especially in the budget), when air-water cooling of the treated area is not used, or it functions in a volume that does not meet the modern requirements of tooth preparation for caries. Overheating of the solid tissue with a drill leads to burns and pulp necrosis, which causes severe pain under the fixed filling. In other words, violation of the caries treatment protocol leads to the fact that pulp inflammation leads to new diseases - pulpitis or periodontitis.
  3. Inflated by bite filling. In some cases, the sealed tooth hurts when biting. The fact is that caries treatment is most often carried out under anesthesia, therefore, it is difficult to determine the height of the bite fillings. The patient cannot say for sure whether the filling is hindering him or not, as this is hampered by severe numbness in the mouth (sometimes not only the bad tooth is felt badly, but even those adjacent to it). If a filled tooth hurts exactly when pressed, there is a feeling that the filling is too high, and you want to “push it” on the bite, you should immediately contact your dentist.

There is a well-established opinion among the people that the bite-filling seal “will get used to it”. In fact, this is a false and dangerous notion, as an overestimated filling not only causes pain in the sealed tooth, but also provokes injury to the surrounding root tissue, which leads to the risk of traumatic periodontitis (inflammation of the surrounding root tissue), and this already carries the threat of tooth loss.

  1. Polymerization stress. Modern light-cured composites (light fillings) have a negative property - to cause the so-called polymerization stress, or shrinkage of the fillings, because of which the tooth begins to hurt some time after filling. During the curing of the material with a special lamp, it loses in volume and causes stress on the walls of the tooth, which are superimposed on the dentist. The more a layer of fillings was applied, the more severe this stress will be in most cases. As a result, non-observance of the technology of working with light fillings leads to the fact that after filling the tooth sometimes hurts a lot, and the pain can be either short-term (up to 1-2 weeks) or not at all.

Cause of pain after canal filling

The pain after the filling of the tooth canals does not always occur in all clinical cases. Some dentists are of the opinion that, normally, after filling the canals in the tooth, there should be no pain at all. В то же время отдельные практикующие специалисты считают, что все-таки кратковременные болезненные ощущения в зубе без «нерва» находятся в пределах допустимой нормы, даже если работа в каналах была проведена согласно протоколу лечения и без ошибок.

Итак, какой характер зубной боли может быть после пломбирования каналов:

  • Боль при надкусывании на запломбированный зуб. After the dentist has put a temporary filling on a tooth, after a few hours or the next day, pain may occur when pressing on it. Many patients note that pressing a filled tooth is especially painful during a meal. If no errors were made during the treatment of the canals of the tooth, then the cause of such pain is the reaction of the tissues surrounding the tooth root to the “nerve” removal, processing, expansion of the canals and the introduction of filling material into them. Usually, a filled tooth hurts no more than 5-7 days, sometimes up to 2-3 weeks. It depends on the material used for sealing the channels and the individual reaction of the body in response to the “stimulus”. In any case, a tooth normally treated in the canals should have a positive dynamic: the pain should gradually subside until it disappears completely.
  • Aching pain after treatment. After the canals are sealed, sometimes aching toothache occurs under the filling immediately after anesthesia. As a rule, its duration is no more than 1-2 hours. If the aching pain does not pass for a long time, and especially if its intensity increases every day, then you should immediately contact your dentist for an explanation.

Does it hurt to fill a tooth?

Tooth filling during caries can be carried out without anesthesia, if no sensitivity occurs during its processing. If a good “freezing” (anesthesia) is made, then the pain does not occur at any stage of the treatment. In the treatment of canals, with rare exceptions, anesthesia is always required, which makes the treatment painless.

We can not say about the options for complications that occur during and after canal treatment. Sometimes a toothache after their filling can be a direct consequence of certain errors on the part of the doctor.

The most common medical errors that occur during channel treatment:

  • Filling of the channel with the removal of material beyond the root. This error leads to long-lasting pain when pressing on the tooth, despite the correctly installed seal.
  • Filling of the canal is not to the top (apex). The channel should normally be sealed to the full working length. If this does not happen, then it is empty at a certain section. Nature does not tolerate emptiness, so microbes accumulate in the non-sealed area, which further provoke inflammation at the root. In some people, immediately or after some time, there is either a aching pain under the filling, or a sealed tooth hurts when pressed on it. In this case, retreatment and channel resection is required.
  • Break off the tool in the channel. In this case, the complication arises because a piece of a dental instrument with an infection source — an inflamed “nerve” or bacteria not washed out of the channel — is left in the canal. In the future, this often leads to pain after filling the tooth canals - immediately or after several weeks (sometimes years).
  • Poorly processed feeds. Due to lack of professionalism or the complexity of the canal structure, the dentist can sometimes not properly clean them. And any area left unattended inside the root is the risk that the tooth will hurt under the filling. Often, the transition of infection to the surrounding root tissue leads to a struggle to re-save the tooth in the future.

How to relieve pain at home after tooth filling

If, after cleaning the canals and setting the fillings, you have a toothache (post-filling pain), then there are several approaches to eliminating unpleasant sensations.

Generally speaking, if the dentist did not make any mistakes, then there is no need to assign rinses, but some experts recommend that you relieve pain with warm rinses with soda and salt.

Salt and soda have long been known in folk medicine as a means of getting rid of many pains. The mechanism of their action is due to the fact that they have anti-inflammatory and antiseptic effects. It is widely known that salt is able to actively “pull over” pus, which, for example, together with soda is used as a solution for rinsing an open channel with the purulent form of periodontitis of a tooth.

So, what to do if there is a toothache under the filling? If a tooth hurts under a temporary or permanent filling, you can start warm rinsing with soda and salt, and preferably as soon as possible. At the same time, it is necessary to warm the tooth from the inside, but in no case should it be outside (it is not necessary to press the cheek against the radiator).

For the procedure, you need to make a little more than warm (as your mouth tolerates), rinse solution, adding a teaspoon of soda and a teaspoon of salt to a glass of water. Rinse should be 4-5 times for an hour until the complete disappearance of pain.

From the experience of the dentist

In some cases, 2-3 drops of 5% iodine tincture can be added to a solution of soda and salt. However, it is worth remembering that for some people iodine preparations are contraindicated due to individual intolerance or problems with the thyroid gland.

If you have a first-aid kit on hand, then you can look for drugs of general anesthetic action, such as: Ketorol, Baralgin, Nise, Ketanov, MIG 200.

When you need the help of a dentist

As noted above, sometimes after canal treatment and filling, serious complications arise, which can further lead to pain in a filled tooth.

Crucial here is the timely referral to a specialist for advice. This is especially important if after the filling of the canals the gums start to hurt and swell up.

In order to understand the essence of the problem, the dentist will definitely clarify the diagnosis with which the first treatment was made. If you put a filling during caries, and the tooth then hurts for a long time, then the dentist will inspect the installed filling, palpation of the gums, percussion of the tooth (tapping), make EDI to clarify the viability of the pulp and X-ray diagnostics. If inflammation of the “nerve” is confirmed, or, even worse, inflammation at the root, then in order for the tooth not to hurt under the filling, the doctor will extract the entire pulp from the canals and seal them along the entire length.

If the “dead” tooth hurts after filling the canals, the dentist will definitely take an X-ray. If errors are found in the treatment carried out, the tooth will be broken. In rare cases, when it is impossible to overfill a tooth, the doctor will offer to remove it, and in its place put either an implant with a crown, or make a “bridge” with an artificial tooth.

A question to the dentist: “Immediately, as soon as I had a filling, the tooth began to hurt badly, why?”

If a tooth was placed on the tooth about caries, then the pain after it fell out is due to the fact that a large area of ​​sensitive and unprotected tissues opens up for the stimuli. Often, the filling takes off because the tooth was prepared poorly: carious tissues were not removed, so tooth decay continued under the filling.

Toothache after caries treatment

Pain after dental fillings can be observed not only with the development of complications, but also be a normal reaction of the body to an intervention, accompanied by micro injuries of various tooth structures. Most often, the expressed pain is of short duration, persisting for several hours after visiting the dental clinic, gradually subsides and completely disappears on its own within a few days.

Dental treatment

How long can a tooth hurt after filling?

The duration of the discomfort associated with the installation of the seal varies depending on the size and depth of the carious lesion, about which the treatment was made.

  • Severe pain should pass within a few hours after completion of the manipulation.
  • The aching pain and discomfort passes within 3-5 days.
  • In the case of treatment and filling the root canal with a composite, the pain may persist for 1-2 weeks, increase with pressing the tooth and be pulsating, but completely disappears in 2-3 weeks after the permanent filling is installed.

Why does the tooth ache under the filling

Pain response is the physiological response of the body to dental intervention and develops due to damage to the structures of the tooth during its preparation for treatment. When biting and chewing, it occurs as a reaction to the preparation and damage to the dentin tissues during drilling of the carious cavity; the closer the carious process is to the pulp, the stronger the pain will be.

Such sensations appear in response to external stimuli (ingestion of cold or hot food and drinks, mechanical pressure on the coronal surface during chewing) and at rest hardly bother the patient.

When drilling out a carious cavity, avoid damage to the dentin.

Severe pain over time may indicate inflammatory processlocalized in periodontal tissues.

Perhaps the occurrence of radiating pain and pulling sensations in the adjacent teeth due to the conduction of nerve impulses from the pulp of a sealed tooth.

After passage and sealing of root canals, the pain can persist for a long time. it associated with greater trauma dentin and periodontal.

When you need to consult a specialist

  • If the sealed tooth hurts and aches for 2 weeks or more.
  • The onset of acute throbbing pain.
  • The deterioration of general well-being, increasing body temperature to 37.5 ° and above.
  • The appearance of bad breath, pus taste on the tongue.
  • With a pronounced swelling and redness of the gums, the appearance of purulent discharge in the region of the gum pockets, the top of the tooth.
  • The feeling of incomplete closure of the dentition, the occurrence of pain when biting or chewing.
  • In the event of a fracture of the seal and the loss of part or all of the array of filling mass.

What to do to get rid of a toothache at home

To reduce pain in the first few weeks after dental treatment, you must follow a number of simple rules.

  • Do not eat too hot or cold food and drinks.
  • Do not eat coarse food that requires biting and chewing thoroughly.
  • Restrict the intake of sweet and sour foods.
  • If possible, reduce the mechanical load on the sealed tooth, do not chew on it, and do not press.
  • Observe adequate oral hygiene, use rinsing solutions and dental floss after each meal.
  • Stop smoking.
Discard coarse food.

Medication painkillers

The main drug group for the treatment of toothaches currently are drugs from the group of NSAIDs, are available both in tablet form and in the form of ointments and gels.

  • Ketanov effectively removes pronounced pain syndrome, has anti-inflammatory and antipyretic effect. The effect develops 20-30 minutes after administration and lasts up to 10 hours, which allows to reduce the frequency of taking the drug. Assigned to 1 tablet (10 mg) after meals, if necessary, can be taken repeatedly. The maximum daily dosage is 40 mg (up to 4 tablets per day).
  • Calgel - dental gel, when applied topically has a complex effect. Contains in its composition lidocaine, due to which pain inhibition is achieved 5-10 minutes after application to the gum surface in the region of the diseased tooth. Inhibits the growth and reproduction of bacterial flora, preventing the development of an infectious process in periodontal tissues. Can be applied up to 6 times per day.

Traditional medicine

  • Propolis tincture used in the form of mouthwash or applications, effectively relieves pain and prevents the development of inflammation due to essential oils and steroids. To use a few drops of tincture applied to a cotton or gauze swab and applied to the patient's tooth for 20-30 minutes before the pain subsides. To rinse a teaspoon of tincture, it is necessary to dilute in a glass of boiled water at room temperature and irrigate the oral cavity 4-5 times a day if discomfort occurs in the area of ​​a sealed tooth.
  • Rinsing the mouth with a solution of baking soda and salt with the addition of iodine after each meal.
  • Tincture of valerian and lemon balm possesses anesthetic and antibacterial properties, for relieving pain, these tinctures are used in the form of applications.
  • Treatment of the gingival surface in the area of ​​the treated tooth with clove oil several times a day will significantly reduce pain.

Possible complications after tooth filling

Negative consequences after dental treatment can occur in case of non-compliance with the filling technique by a dentist, poor-quality filling material and failure of the patient to follow the recommendations for oral cavity care. Possible complications include:

  • the progression of the process under the filling with insufficient preprocessing of the carious cavity,
  • overestimation of bite with an excess of filling material,
  • fracture of a seal, its partial or complete loss,
  • discrepancy between the fillings and the color of the tooth enamel,
  • inflammation of the interdental papillae (papillitis),
  • formation of cysts in the apex of the tooth,
  • allergic reactions to composite materials used for sealing,
  • acute and chronic form of apical periodontitis,
  • darkening of the dental crown.


In most cases, the pulling sensations and discomfort after filling the teeth go away on their own within a few days and do not require additional treatment, but in case of their strengthening or worsening of general well-being, it is necessary to consult a dentist to determine the cause of the pain syndrome and select appropriate therapeutic measures.

Causes and Effects

Most people watch their teeth. They clean them, use special rinses and visit dentists. It happens that despite taking care of the teeth, the disease begins to ruin them. Then you have to clean your teeth and fill them. This is a rather complicated procedure, which consists in cleaning the crown of the tooth from the tissue elements, which is damaged, drying and subsequent laying of the material. And many people ask themselves: why does a tooth ache after filling? Is the doctor breaking technology? Poor quality materials or old inefficient equipment? What is the reason?

After filling a toothache - do not rush to blame the doctor or technician. Yes, they can cause inconvenience, but these cases are rare. Most often, we experience acute or aching pain. It is expressed in sensitivity to certain characteristics of food, such as cold, heat, sweetness, acid. Moreover, the unpleasant consequences can manifest themselves after an hour, and after a few days.

What to do?

Practical experience shows that the most important in this case is a competent diagnosis. Therefore it is necessary to consult a doctor. It is desirable to the one that installed the seal. If for some reason he is not satisfied, then you can change it to someone else. It often happens that after the recovery process, a person is pursued by phantom pains. If a tooth hurts under the filling after filling the canals, then this option is very likely. But it is very desirable that such a diagnosis be confirmed (or denied) by a qualified specialist. Keep in mind that if there is swelling, and it does not fall down for two days, and, moreover, is accompanied by significant pain - then the direct road to the doctor. It is the most correct to advise what to do if a tooth aches after filling, it will be an experienced qualified person who can.

Why do complications arise?

The most common cause is nerve damage due to the procedure of interventions in tissue structures. That is why the tooth hurts after filling with pressure on it, including when eating food. The most desirable option is to prevent a situation that provokes pain. Such phenomena may last for several days. In some cases, the nervous system may need a couple of weeks to deal with the situation. After that, the pain goes away.

But be careful - if the tooth causes inconvenience for a month (or a little less), then you need to consult a doctor. It may be necessary to carry out the removal and cleaning of the tooth canals. If this is all normal and there is no damage to the nervous tissue, then you can seek advice on the acquisition of toothpaste, which will help reduce the sensitivity of the enamel. After that, clean the mouth quite regularly and everything will pass. If you do not want to wait, you can resort to fluoridation.

Suppose the question arose why a tooth aches after filling the canals with gutta percha. Another possible option is an allergy to the material that was used in the work. In addition to pain and discomfort, in this case, there is often a series of unpleasant accompanying manifestations. For example, itching, rashes and the like. При наличии этих симптомов удаляют пломбу и ставят новую из материалов, которые не будут вызывать раздражения. Могут возникнуть неприятные ощущения и из-за повреждения искусственного покрытия. Следует помнить, что пломбы сделаны из обычных материалов, которые изнашивается в процессе эксплуатации.Much depends on the culture of use and the quality of the work done. Fresh fillings may be rejected if poor preparation has been made. For example, over- or not dried the wall of the tooth. Although it may also be damaged due to biting - this is true for those who neglect the advice of dentists not to eat food after treatment.

Medical factors

But, speaking about the problems and why the tooth hurts after filling the canals, it is still impossible to ignore the human factor. So, if the pulp is not sufficiently blocked by a filling, then harmful microbes can take advantage of this. Once in the dental canal, they will, at a minimum, cause local inflammation. Also, an illiterately installed seal can create an excess of pressure, which will be accompanied by characteristic pain. Therefore, in case of inconvenience, it is advisable to visit a specialist who can figure out what is happening and, if necessary, provide first aid.

Root Canal Problems

When there is a question about why a tooth aches after filling gutta-percha, then there may be several options. The most common problems with root canals. How to define them? If prolonged pain arises from temperature fluctuations that last for minutes, then it is highly likely that the inflammatory process of the dental nerve is going on. When can it appear and how?

Usually, the pain slowly increases due to improper installation of a seal or complications after the procedure, as a result of a drop in immunity. For example, it can occur in a stressful situation or because of a cold when the body is weakened. This is another option why a tooth ache under the filling. Causes (first aid is professionally provided only by physicians) are identified by specialists. Therefore, you should not hope at random, and if the pain does not recede, you need to visit a specialist.

If unpleasant sensations appear only in one tooth while eating food or when pressing on it, this suggests that there are inflammatory processes in the tissues near the root. Or that periodontitis has already developed. No matter how it is, the only way out is to professionally process the root canals. In this case, to delay the visit to medical institutions is not recommended.

About the consequences

Why not to pull? If you visit dentists every six months, then you can get by removing small spots of caries. Maximum - the canals will be cleaned, medication processed and a seal will be installed. If you start the treatment, you can get serious complications of diseases, from osteomyelitis to cellulitis. In addition, the timely removal of damaged tissue or nerve will save the tooth.

Work of the nervous system

Let's look at one myth. Many people believe that if there is no nerve, then the pain will not be felt. The truth is present in this statement, but not everything is so simple. Why? The fact is that the nerve fibers that go out through the hole in the tooth root are connected to the common trunks. Thanks to them, we can feel a lot of pain.

If there are significant inflammatory and purulent processes, then the nerve is removed (detached from the main trunk. It injures the tissues. When the tool passes through the tooth, it is not felt because they clean the canals under the influence of the anesthetic. At the same time, the doctor must a hematoma did not form. If it was allowed to occur, it would result in the appearance of a painful syndrome when trying to compress the lower and upper jaws.These unpleasant sensations can last up to two days. If the dental cavity was well cleaned, according to the developed and approved technology, then the person should not be bothered by any pain. If the situation is different from that described, then the procedure must be repeated.

What is included in the treatment?

Initially, the problem area is processed. Then it is cleared. It is dried. This is followed by filling with special materials. For them are used pastes with additives that have anti-inflammatory effect. In order to avoid creating conditions for the reproduction of bacteria, the channels are sealed. If a particle of infected tissue gets to the top of the root, the inflammatory process will spread. In this case, the pain syndrome will be pronounced. It will manifest itself in the form of pulsation, twitching, reaction to hot food. The presence of these symptoms suggests that the channels need to be treated again, because anti-inflammatory medications have a short period of effective activity. But if the processing was carried out qualitatively, it is unlikely that this will be the need.

Temporary and permanent solution

Remove teeth, few people want. Therefore, if there is a chance to eliminate the inflammatory process, then the root canals are processed.

They leave for one or two weeks turunda containing anti-inflammatory agent. Above, in order to avoid the ingress of microbes, they place a temporary seal. After the allotted time has passed, the doctor looks at the site of inflammation. If all is well, then he puts a permanent seal. In cases where the desired result is not achieved, appropriate procedures are carried out. You should not be afraid of nerve removal or channel treatment The use of modern painkillers allows you to effectively carry out these processes without suffering.


The best problem is the one that was solved before it arose. This is truly the golden rule. So is the case with the teeth. How to prevent problems? The simplest and most obvious is to brush your teeth regularly. The best option - every time after eating. The truth is difficult to imagine, and most people clean them once or twice a day - in the evening and in the morning. At the same time, it is necessary to ensure that the toothbrush is not worn out and can perform its direct functions. After cleaning, you can rinse the mouth with a rinse. If you do not want to buy a special tool, then use soda solution as a temporary replacement. You can also refrain from eating sweet and sticky food, which adversely affects the condition of the teeth. We should not forget about immunity, because infections develop quite actively in a weakened organism.

Is it possible to be treated at home?

Diseases of the teeth are similar in nature to such problems as appendix or curvature of the nasal septum. But in such cases, no one does an operation in front of a mirror, right? Problems with teeth just do not correct themselves. And if there is at least a small black spot, then without options you need to go to the doctor. But if all the violations so far are represented only by a white spot on the tooth enamel, then the matter can be corrected. For example, using special gels that are engaged in the restoration of tooth enamel. Or you can make a tincture of sage, propolis, onion peel, calamus, camphor.

If there is a sharp pain, then it will help to remove garlic and fir oil. If the inconvenience continues for several days, you should contact a qualified specialist for medical assistance. On this, perhaps, everything. That is why the tooth hurts after filling and what to do to eliminate unpleasant sensations.
