Root canal treatment is necessary when the infection is extended to the radical nerve of the tooth. The treatment is performed by removing the entire infected nerve and through the placement of a special antibacterial drug inside the root canals.
Root canal is the choice of treatment in permanent and primary teeth, when the caries is extended to the radical nerve or when a tooth has been severely injured and cannot be restored with any other method. Then, the tooth is restored either with normal filling or with a stainless-steel crown in cases with extensive loss of the tooth tissues.
