A root canal treatment is a procedure to save badly infected or fractured tooth. It involves removal of the affected nerve (pulp) and decayed part of the tooth. In turn, the removed part is replaced by inert dental materials. If needed the dentist places a crown (cap) to help the tooth regain its form, function and esthetics. With modern equipments like apex locators, rotary instruments, RVG and much more, the treatment becomes relatively simple for both, the patient and the doctor.
