Your tooth has been killed and the nerve removed. But after the anesthetic wears off, for 3 days you feel discomfort and dull pain, which you can control only with painkillers. The reaction of the tooth to cold or heat in the first days after killing it is considered a normal reaction.

In the period after the procedure, you should pay attention to the nature of the pain and some other alarming symptoms. If the pain doesn't subside, but gets worse day by day, if you find it uncomfortable to chew, if your temperature rises, if your cheek or gum swells, go back to your dentist.

The strong, sharp and unrelenting pain soon after killing the tooth and passing the action of the anesthetic is most often a sign of broken treatment technology and mistakes made by the dentist. Here are some options:

► Tooth damage - perforation. In the treatment process, more precisely in the mechanical treatment of the carious cavity and canals, there is a possibility of perforation of the bottom or immediately of the root canal, as a result of which the bone is reached.

► Breakage of a dental instrument in the canal of the tooth. Such an unpleasant situation can happen for various reasons. If, for example, the metal is "worn out" as a result of repeated sterilization and long-term work with it. Often, the instrument breaks due to the specificity of the anatomy of the root canal - if it is curved or has calcifications.

It is not rare that after the pulpitis has been cured, the tooth "reminds" itself weeks, months, even years after the treatment. What are the reasons for feeling pain and discomfort in the "dead" tooth?

► Incomplete pulp removal. I.e. when cleaning the canals, the nerve is not completely removed. Over time, it can manifest as pain when taking hot or cold food or drinks.

► Skipped cleaning of one of the channels. To avoid such a mistake, the specialist should start the treatment after being provided with an X-ray.

► Poor sealing of the canal. If part of the canal remains unfilled, pathogenic bacteria accumulate in it, which leads to the development of periodontitis (inflammation of the ligaments fixing the tooth in the jawbone). Exit of the filling material beyond the limits of the tooth roots leads to excessive pressure on the periodontal tissue, provoking a painful reaction.

► Increased pressure on the tooth with an incorrectly placed filling. In this case, the dead tooth is loaded, which in turn increases the load on the ligaments and causes a feeling of pain, especially when pressure is applied to the tooth.

► Insufficient hygiene. With a correctly performed tooth filling manipulation, there is still a possibility that bacteria will get into the roots of the tooth if you do not clean your teeth properly. Even with the best seal, germs build up with poor hygiene. Over time, they destroy the filling material and penetrate the root, causing inflammation and pain.

► Localized gingivitis and periodontitis. They occur due to pressure and trauma to the mucous membrane of the gum above the filling. Insufficient hygiene of the oral cavity and accumulation of tartar in the area around the gums can also be the cause of such inflammations. Itching, pain and bleeding occur.

► The “living” adjacent tooth hurts. It is not always possible to determine exactly which particular tooth hurts. In some cases, the cause of the unpleasant sensations may not be the "dead" tooth, but the adjacent "living" one affected by caries.

If the filled tooth hurts, should it be removed? This is a last resort method of treatment. The dentist still tries to save the tooth, if possible, by conducting conservative treatment. For example, in the case of poor-quality sealing of the canals, the specialist unseals them, cleans the roots and re-seals, having previously sent the patient for a photo. If the dentist diagnoses a complication - periodontitis, he can prescribe antibacterial preparations, antihistamines and painkillers.

Unfortunately, complications after pulpitis treatment are not rare. They are not always related to mistakes by the dentist. Very often, these complications depend on the features of the structure of the maxillofacial area, as well as the duration of the disease. The appearance of pain and discomfort in a filled tooth is always a reason to seek help as soon as possible to avoid further deterioration of the situation.
