When a previously root canal treated tooth becomes re-infected, it is called root canal failure. The common causes of root canal failure are improper cleaning of the root canal, undetected root canal, inaccessible root canal, and root fracture. The treatment options of a re-infected tooth are doing a root canal again, apicoectomy, or extraction.
