Proud Members of

A dentist who specializes in root canal treatment is called an Endodontist. This procedure is performed to remove damaged tissue from inside the root canals of a tooth. Endodontists limit their practice to performing these specialized endodontic procedures.

Advanced surgical and nonsurgical skills are necessary to qualify a dentist for Endodontics. This makes them uniquely qualified to treat the routine and complex cases each individual patient presents. After attending a qualified dental school, a dentist wishing to specialize in Endodontics attends a two or three year advanced dental school program. This intensive education prepares them to perform the very best in Endodontic procedures. Additionally, they continue to update and manage their training after entering into practice to keep knowledgeable about state-of-the art procedures and technology.

All About Endodontics

Endodontics is the branch of dentistry which is concerned with the morphology, physiology and pathology of the human dental pulp and periradicular tissues. The study and practice of Endodontics encompasses the basic clinical sciences including biology of the normal pulp; the etiology, diagnosis, prevention and treatment of diseases and injuries of the pulp; and associated periradicular conditions.

The scope of endodontics includes, but is not limited to, the differential diagnosis and treatment of oral pain of pulpal and/or periradicular origin; vital pulp therapy, such as pulp capping and pulpotomy; nonsurgical treatment of root canal systems with or without periradicular pathosis of pulpal origin and the obturation of these root canal systems; selective surgical removal of pathologic tissues resulting from pulpal pathosis; repair procedures related to such surgical removal of pathologic tissues; intentional replantation and replantation of avulsed teeth; surgical removal of tooth structure, such as root-end resection, hemisection, bicuspidization and root resection; root-end filling, endodontic implants; bleaching of discolored dentin and enamel; retreatment of teeth previously treated endodontically; and treatment procedures related to coronal restorations by means of post and/or cores involving the root canal space.
