Endodontics it is a department of conservative dentistry dealing with the diagnosis and treatment of tooth pulp ("nerve") diseases and the diagnosis and treatment of periapical tissue diseases. The basic method of treatment here is root canal treatment carried out with the use of hand and machine files. Modern endodontics uses X-ray diagnostics and endometers to precisely determine the working length of the canals.

In complicated cases, endodontic microscopes are used. The root canal treatment process completes the tight filling of the canal

Spontaneous toothache occurring with increasing frequency may be a sign of ongoing inflammation in the pulp pulp. A visit to the dental office in the first days after its appearance can prevent irreversible inflammatory changes and gives us the chance to avoid root canal treatment.
