What to do if a tooth ache after filling?

Tooth filling is the process of artificially restoring the anatomical and structural shape of a tooth with the help of special materials. Often, patients who performed this procedure complain about the occurrence of pain in the tooth.

Many associate this with the effect of dental equipment on dental tissue. The reasons for which a tooth aches after filling during bite can be much more, so it is important to understand them and know how to quickly get rid of a toothache at home.

How is the filling?

The process of tooth filling includes:

  • expansion of the cavity of the damaged tooth with a drill;
  • drying the entire tooth surface;
  • removal of injured, dead, damaged tissue;
  • treatment of the cleaned surface with special glue;
  • installation of a special gasket;
  • the process of installing a seal;
  • polishing seals;
  • fitting the seal to the overall appearance of the teeth.

Most often, the procedure goes without any problems and pain, if it occurs, is temporary. If there is a sharp and long-lasting pain, then something went wrong and you need to rush to the dentist again.

Causes of pain in the tooth after installing the seal

After treatment of pulpitis, and in rare cases, and after treatment of caries, the patient may experience pain for some time. Most often after filling a tooth ache, if it is pressed, bite off food or pain appears when there are temperature stimuli, when eating sour, spicy or sweet food.

Within a few days, sometimes weeks, similar phenomena disappear. They are caused by the fact that nerve endings were damaged in the process of interfering with the integrity of the tissues. Just try to avoid situations that can cause pain in a cured tooth.

Even in cases where complex treatment was performed with gum damage, and all the manipulations were performed correctly, dental tissues and periodontal traumatized and may hurt slightly. But it is worth knowing that the discomfort during 2 - 4 weeks should disappear completely. But if after filling the tooth hurts for a long time, and no relief is felt, it means that there is some pathology, and you need to go to the dentist again.

Often post-filling pain occurs when:

  • pressure on the sealed tooth in the process of chewing food;
  • when the surface of a cured tooth comes into contact with other teeth;
  • under the influence of irritants (cold air, hot or cold drinks, etc.)

Below we consider the common reasons for which a tooth hurts after filling:

  1. A common cause of tooth pain after filling is a violation of the technology or treatment of the tooth. For example, when the filling material goes beyond the limits of the dental canal, or when remains of enamel and pathological tissues remain under the filling. In such situations, inflammatory processes develop, in which pain is inevitable.
  2. When a tooth hurts after filling the canals and removing the nerve, the cause may be incomplete removal of pulp tissue or when filling the canals or cavity of the tooth voids are formed, which cause secondary inflammation of the tissues.
  3. There are cases when the front or other tooth hurts a few days after filling, and the pain is wave-like, arising during eating and subsiding after the cessation of exposure to the tooth. This may indicate the development of chronic pulpitis, which is also most likely the result of dental errors.
  4. Not completely removed caries. With a strong destruction of the tooth, in addition to the removal of dead tissue, anti-inflammatory treatment of the cavity is often required, with a temporary filling. An inexperienced or overly confident doctor can ignore this procedure. In this case, a toothache after a visit to the dentist can be very strong, since the inflammatory process develops more intensively in a tightly closed space than in an open one. Repeated inflammation of an already cleaned cavity during caries can lead to pulpitis.
  5. Poorly completed filling. Even an experienced dentist can make a mistake. A tiny piece of a cracked instrument, incomplete removal of inflamed tissue, or incompletely sealed space — any of the above causes pain and requires correction.
  6. Allergy. Hypersensitivity to the filling material rarely causes inflammation and pain in the area of ​​the tooth.
  7. Not followed the recommendations of the doctor. In order not to worry about how much the tooth is disturbed after treatment, it is necessary to strictly follow the advice of the attending specialist.

Self-diagnosis is ungrateful and very difficult. Dentists consider the occurrence of recurrent pain in the tooth after filling with chewing or chewing food to be normal, provided that these pains disappear in 2-3 days, and the patient's condition does not worsen. If the pain in the tooth after treatment does not go away after a few days, it will not be possible to avoid a second visit to the dentist - most likely, additional treatment or examination will be required.

How much does the tooth hurt after canal filling

A case from the dental practice:

A week ago, a nerve was removed. Channels are not sealed, because x-ray didn't work. After 4 days, they cleaned, sealed the canals, took a picture: the canals were sealed well, put a temporary seal. Everything was fine. A day later they put a permanent filling, and as soon as I left the clinic, it became unpleasant to press a tooth. The next day it hurts to press the tooth, chew and touch the tongue. Outside to the gums unpleasant to touch. This is normal?


Pain after the canal filling can disturb a couple of days. We recommend that you always contact your doctor, because the pain that has appeared may be associated with even a slight overbite on the bite, and this problem will not go away - correction by the doctor is necessary.

What to do?

If the tooth is sore after the canal filling, you need to go to the dental clinic as soon as possible, you may need to remove the filling and re-treat it, and you will not be able to cope with this problem at home.

To alleviate the patient's condition and reduce pain in the tooth when biting, you can use these tips:

  1. The easiest way to use painkillers: Ketorol, Baralgin, Nise, Ketanov, MIG 200, etc.
  2. A proven way to reduce toothache is considered to be rinsing the mouth with soda-salt solution: 1 teaspoon of salt + 1 teaspoon of soda, dissolved in a glass of warm water. Rinse every 1 - 2 hours. To the finished solution, you can add 5 drops of iodine.
  3. Press to the aching tooth for 10 minutes. cotton swab soaked with a small amount of fir oil (5-6 drops is enough). It is necessary to control that the compress does not touch the gums, as this may cause its burn.

However, do not get too carried away with medication and exceed their normal dosage. If the pain is so severe that it is necessary to "turn off", it is better to see a dentist.

Prophylactic procedures

After installing a seal on a tooth, it is important for the first week to follow the rules that will help minimize the possibility of pain.

To do this, follow the simple rules of prevention:

  1. Less smoking.
  2. Give up sweets.
  3. Do not eat too hot and cold.
  4. Give preference to soft and liquid foods that do not need to crack.
  5. Do not chew filled teeth, try to minimize the burden on them.

If the tooth still hurts under the filling, then the necessary knowledge of first aid will ease the condition. And the understanding that dental problems should always be solved by a doctor will ensure the health of the teeth and gums.
