Damage to your tooth, even a tiny crack, can allow bacteria to reach the pulp of your tooth. Once an infection sets in, the result can be painful and you may experience health issues that affect more than just your smile. If you are dealing with a painful or sensitive tooth, call Semtner Dental at 540-989-0112. Our dentists can see you for a visit for root canal therapy in Roanoke, Virginia. Dr. Rob Semtner, Dr. Mona Semtner or Dr. Adam Holt can use this treatment to save your tooth and keep your smile intact.
