Root canal therapy becomes necessary when the inner nerve of a tooth becomes affected by decay or infection. When this happens, the tooth may become extremely sensitive to both pressure and temperature, and intense pain can be expected. Call Stanford Dental at 636-256-3559 if you are experiencing these symptoms, as you may need a root canal in Ballwin, Missouri. Dr. James Stanford, our skilled dentist, will perform the procedures necessary to restore your mouth to its original health.
