Endodontics or "root canal treatment" as it is more commonly known, is required when the blood or nerve supply of the tooth (the pulp) is infected through decay or injury. The aim of the treatment is to preserve the tooth by removing all traces of infection and then filling it to prevent further infection.
Endodontic therapy is a highly successful procedure, which is usually carried out over one or two appointments. After endodontic therapy the tooth continues to receive support from the surrounding tissues and may be expected to last as long as any other natural tooth.
