Endodontics (from the Greek endo "inside"; and odons "tooth") is one of the dental specialties recognized by the American Dental Association and deals with the tooth pulp and the tissues surrounding the root of a tooth.
Endodontics is the science of treating problems with the tissue inside the tooth. When this tissue or the tissue surrounding the tooth root is diseased or damaged due to decay or trauma, endodontic treatment typically can save the tooth. Endodontists perform a variety of procedures including root canal therapy, endodontic retreatment, surgery, treating cracked teeth, and treating dental trauma. Root canal therapy is one of the most common procedures. If the pulp (containing nerves, arterioles, venules, lymphatic tissue, and fibrous tissue) becomes diseased or injured, endodontic treatment is required to save the tooth.
