Damage to your tooth, such as a cavity or even a crack that is almost impossible to see can allow harmful bacteria to reach the pulp at the center of your tooth. This infection can result in a lost tooth and other oral health issues. At Dental Care of Frisco, our dentist can treat this problem with root canal therapy in Frisco, Texas. If you have a sensitive tooth and want to keep your smile intact, call 214-436-5122 for an appointment with Dr. Thomas Grant.
