All dentists are trained in school to perform root canals, however not all dentists feel comfortable tackling all root canal cases depending on their level of training and skill. For example, Dr. Eastwood will do root canals on all teeth including molars, but if a redo root canal is needed on a tooth he refers the patient to a root canal specialist (endodontist) to ensure the redo root canal has the best chance of success. Endodontists are dentists who have gone through additional schooling to specialize in performing root canals, and mainly treat failed root canals.
