The root canal is the space inside the root of the tooth, and can be affected by bacteria, dental diseases or injuries. If the patient is diagnosed with pulpitis/tooth root inflammation or periodontitis, the dentist can treat the tooth with root canal filling. Treatment is done painlessly under anaesthesia, and the shape and function of the tooth is restored.

After dental treatment, the dentist always checks how the canal is filled. The filling material should fill the entire space up to the top of the root. If the canal is not sufficiently filled, an infection will develop with the formation of granulomas or cysts. If it is overfilled, the tooth may be damaged and the lips or chin may feel numb.

Gutta-percha or metal posts are necessary to increase the strength of the tooth root after filling. Installation of the pin is a mandatory part of the treatment which ensures that the seal is of the highest possible quality.

The patient is anaesthetised, and the dentist removes the tissue and tooth pulp that has been destroyed by caries. The dentist assesses the exact length of the root canal, the tortuosity of the tooth root. After treatment and a slight increase in the diameter of the canal, a metal pin will be placed in it or filled with gutta-percha before it is sealed. In case of severe inflammation, the treatment is carried out in two stages – first a temporary filling with antiseptic pastes, then treatment as mentioned above.
