423-271-6075 Most patients who have had root canal treatments do not need retreatment. However, if your tooth does become reinfected, our endodontist can give you a root canal retreatment in Sweetwater, Tennessee. Dr. Bonnie Boudreaux will remove the filling, take out the infected pulp, and then refill your tooth for you.
