There are instances when a tooth does not heal as well as anticipated following root canal therapy. In some cases retreatment by non-surgical means is either not possible or will not offer the best opportunity for healing. These cases include:
- complicated anatomy
- canal blockages
- formation of a cyst
- Under local anesthesia, with the use of a microscope, minimally invasive access to the area of persistent infection is achieved. The lesion is removed along with a small section of root containing bacteria. A biocompatible filling is placed and most patients leave with only a few sutures which are removed at our office within a few days. In all, most procedures are completed in an hour and recovery time is usually 24 hours. Most patients are surprised at how easy, comfortable and uneventful the experience is.
