Although most root canal procedures are done non-surgically, sometimes situations require root canal surgery to get you healthy and comfortable again. This type of surgery is called endodontic microsurgery.
Traditional root canals are the most common treatment for most cases. But sometimes teeth may need to be treated surgically following a root canal. That surgery, called an apicoectomy, is done on a tooth when their original root canal was unsuccessful. An apicoectomy is a procedure with over a 90% success rate.
While an unsuccessful root canal can often be re-treated non-surgically, it may require an apicoectomy if the infection at the base of the root could not be resolved or if the bone at the base of the root of the tooth has been affected by the original infection.
Your dentist may refer you to an Endodontist for evaluation for an apicoectomy if you have the following symptoms:
Pain that persists after a root canal
Reinfection after a root canal
Damage to the root or surrounding bone
