In most instances, once a tooth has received a root canal, no further treatment is needed unless our dentist and team recommend protecting the tooth with a dental crown. There may be times when an infection reoccurs, however. If you are experiencing problems with a previously treated tooth, call Richard S. Durando, DDS at 650-323-8328. We can schedule you for a visit with Dr. Richard Durando for a root canal retreatment in Menlo Park, California.
