Tooth decay or a crack that is too small to be seen during a regular exam can allow bacteria to reach the pulp of your tooth and create an infection. That infection can be painful and even create problems for your general health. In fact, if you wait too long, you may even need an extraction. At the first sign of a toothache, call Mosaic Dental. Our dentists, Dr. Anuradha Beri, Dr. Nimisha Patel and associates, can see you for an appointment for root canal therapy in Sterling and Falls Church, Virginia.
