Dr. Kip Litton opened his award-winning dental practice in 1990 and has since provided patients with services like root canals and implants. Root canals are most commonly needed when a tooth becomes infected or decays, requiring the removal of the nerve and pulp inside the tooth to clean and seal the infected area. While root canals have a reputation for being painful, the procedure itself is similar to a normal filling and the referenced pain is actually from the prior infection or damage in the tooth.
