A laser may be used to gain access to the infected nerve and clean, shape, enlarge and sterilize the root canal. Sometimes we will choose to use the laser to perform only parts of the procedure. Advantages of using a laser to perform a root canal are that the procedure may be performed without anesthesia and laser use conserves as much natural tooth structure and strength as possible. The laser also has a greater depth of penetration into lateral walls of the nerve canal than traditional disinfectants and can kill bacteria more completely. Our goal in root canal therapy is to disinfect the root canal and fill the area with an antibacterial material while maintaining as much strength of the tooth as possible. The precise and disinfecting qualities of the laser help dentists achieve these goals.
