A cavity, or even a crack that is too small to be seen during your checkup, may be enough to allow bacteria to reach the pulp at the center of your tooth. The infection can result in discomfort, swelling and problems for your general health. If the issue is not addressed in time, you could find yourself in need of an extraction. If you have a toothache or are suddenly experiencing tooth sensitivity, call Briggs Family Dental at 540-740-3660 for an appointment with our dentist. Dr. Spenser Briggs can see you for root canal therapy in New Market, Virginia, to preserve your tooth and your smile.
