Root Canal Treatment
Root canal treatment (also called endodontics) is needed when the blood or nerve supply of the tooth, known as the pulp, is infected through decay or injury. When the pulp becomes infected it can spread through the root canal system of the tooth, eventually leading to a painful abscess. Infection will spread if root canal treatment is not carried out, and you may have to have teeth extracted in the affected areas.
Root canal treatment is a skilled and time-consuming procedure and most courses of treatment will involve two or more visits to your dentist. The first appointment involves thorough cleansing, any infected pulp is removed, and any abscesses drained. The root canal is then cleaned and shaped ready for the filling. A temporary filling is put in and the tooth is left to settle.
The tooth is checked at a later visit and when all the infection has cleared, the tooth is permanently filled.
