The aim of a root treatment is to treat the internal tissues of the teeth in order to maintain the structure of the tooth. This involves localization, radicular reaming, and sealing of all the root canals. These treatments are in constant progress in consideration with the mechanical techniques as well as the medicine used. The completion of a root treatment often requires several appointments.

The general dentist may refer the difficult cases to a specialist in endodontics who may use a microscope.

A root canal treatment is always delicate, particularly due to the variations in morphology, the difficulty of access and also the necessity to work shielded from saliva (Dental Dam).

In the majority of cases it is necessary to cover the tooth with a crown to protect it from further breakdown.
