Endodontics is a specialized form of dentistry that treats diseases or injuries that affect the root tip or nerve of the tooth and the structures called the pulp chamber, pulp, and root canal of the tooth. Root canal therapy is the most common endodontic procedure.

Endodontic treatment, commonly called root canal treatment, is a common dental procedure that removes damaged tissue from inside the root canals of a tooth, thereby significantly lengthening the life of the tooth. Endodontic treatment significantly restores once damaged teeth and is a recognized and superior alternative to tooth extraction as a means of treating damaged interior structures such as pulp.
