In most instances, once you have had a root canal to address an infected tooth, there should be no further problems. But if a previously tooth area is starting to hurt or the area around it becomes inflamed, contact the team at Redrock Dental & Wellness at 781-599-4505 for an appointment with our endodontist. Dr. Mahua Bose may suggest a visit for a root canal retreatment in Swampscott and Boston, Massachusetts.
