Root canal treatment (also called endodontics) is needed when the pulp inside your tooth becomes infected through tooth decay or damaged by an injury to your mouth. This infection may spread through the root canal system and could eventually lead to an abscess, causing a great deal of discomfort. If root canal treatment is not carried out, the tooth may need to be taken out.
Preservation of remaining healthy tooth structure.
Prevention of infection spreading any further.
Restoration of tooth to its natural look and feel.
