A root canal is usually done by an endodontist or a general dentist. The root canal usually takes one or two visits, but once in a while additional visits are required because some teeth prove difficult to treat. First, you have dental X-rays to check the extent of damage. You also receive a local anesthetic to control pain during the procedure. Then a rubberlike sheet called a dental dam is placed in your mouth around the tooth to keep the tooth clean, protected and free of saliva. Decay is removed, and an opening is made through the crown of the tooth to gain access to the pulp chamber. Using small dental instruments, the infected or diseased pulp is removed.
