Why does a tooth hurt after a filling?

The main cause of pain in the tooth is a carious lesion. If caries is not treated on time, then it penetrates deep into the tooth, and then it is already necessary to take emergency measures – tooth treatment. In dentistry, such treatment is called endodontic (carrying out all kinds of manipulations aimed at preserving the tooth). Caries treatment is the most common dental service, so the dentist needs high qualifications and experience to carry out the procedures, especially in a situation where caries has affected the tooth deeply. In difficult situations, it is necessary to simultaneously treat pulpitis or other pathologies.

However, even after the filling procedure is carried out by the most experienced and qualified dentist, the treated tooth may hurt for some period. Patients return to the dentist repeatedly, indicating intermittent or persistent pain. Most often, this phenomenon is the norm for the body, especially if the situation was neglected and there were complications or infections. For this reason, if the tooth continues to hurt after filling, do not worry, although it still does not hurt to contact a specialist.

Dental treatment is often accompanied by cleaning of the canals and carious cavity, sometimes dentists decide to remove the nerve and seal the canal. After such a serious intervention in the oral cavity and dental tissues, the appearance of minor pain is quite normal.

However, there are other reasons why a tooth may hurt after filling:

1. Post-filling pain.

A similar phenomenon is quite natural, which disappears after 3-4 days. The tooth needs time to get used to the new filling.

2. Incorrect selection of the height of the seal.

Due to this oversight of the dentist, the bite is disturbed, and the tooth can hurt when biting. Under the influence of anesthesia, the patient cannot always determine the height of the filling. Also, a similar situation can occur with poor-quality grinding of tubercles.

3. Do not take x-rays after treatment.

If a detailed X-ray is not performed after the treatment, then there is a risk of incomplete treatment, the canal may not be completed, and pain may occur again, therefore, after treatment, it is imperative to take a control X-ray, if the X-ray was taken and the treated channels are clearly visible in the image, then There is no doubt about the professionalism of Dr.

4. Seal shrinkage.

Even the most modern composites have a shrinkage factor, which must be taken into account by a competent doctor during treatment. If the cavity was filled with an insufficient amount of material, then voids form in it. Enumeration of the material will also cause discomfort and pain. Therefore, it is possible that you will have to come again for a correction.

5. Overheating of dental tissues.

Another problem is if the dentist uses outdated equipment that cannot provide high-quality cooling of the prepared area. Since drills operate very quickly without adequate air/water cooling, there is a risk of nerve burns.

6. Broken instrument in the canal.

Due to the haste and inattention of some dentists, as well as due to the spent canal cleaning material (such material also has its expiration date), it happens that the instrument breaks right in the root canal, such cases happen in budget dental clinics where the instrument used much longer than its lifespan. If the doctor noticed an oversight, then he will certainly eliminate the consequences, but if the fragment is detected only when the patient comes with complaints of pain after some time, repeated procedures will have to be carried out and only under a microscope.

7. Improper drying of the cavity.

If the walls of the cavity are not completely dried, then there can be no talk of reliable fixation of the seal. When overdrying, the tooth becomes hypersensitive.

8. Perforation of the wall of the root canal.

If such a complication could not be avoided, then the specialist must take measures to eliminate the through hole.

9. Poor processing.

A professional processes the dental cavity carefully, even if the structure of the canals has its own difficulties. If the tooth is processed poorly (we are talking about mechanical and drug treatment), then the infection may remain in the focus, which is why the toothache will not stop after filling.

10. Allergic reaction. One of the rarest reasons, but you should not forget about it either. Allergies can occur due to intolerance to dyes and preservatives. If this problem is identified, then the doctor is obliged to select other filling compositions for treatment.

Important!

For 1-3 days after filling the tooth, observe how the tooth behaves. If after three days the tooth does not stop hurting, re-register with the dentist for an examination. The reasons may be different (described above), so only a doctor can accurately tell the cause of a tooth disease.
