"Endo" is the Greek word for "inside" and "odont" is Greek for "tooth." Endodontic treatment treats the inside of the tooth. Endodontic treatment is necessary when the pulp inside the tooth becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, an injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks.
Root Canal TherapyA "root canal," or endodontic therapy, is a procedure available to save a tooth that is infected and would otherwise require extraction. In order to save the tooth, the pulp (nerve and blood supply), bacteria and any decay are removed, and the resulting space is filled with an inert material called gutta percha. After the tooth is healed, getting a crown is recommended.

Root Canal RetreatmentMost endodontically treated teeth last as long as other natural teeth. In a few cases, a tooth that has undergone root canal therapy fails to heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this occurs, root canal retreatment can save the tooth.
