Although our endodontist does all he can to remove infectious pulp and harmful bacteria during a root canal, there are some cases where the infection can return. When this happens, you may require a root canal retreatment. In this procedure, Dr. Anastasios Photopoulos will perform another root canal to clean out the infected area. If you had a root canal and are experiencing pain in that tooth, we invite you to contact AZ Dental at 408-738-1000 and schedule your appointment to learn if you require a root canal retreatment in Sunnyvale, California.
