Apicoectomy – Root Canal Microsurgery

An effective surgical treatment when pain and infection persist after root canal treatment or retreatment.


Usually, a tooth that has undergone a root canal can last for a very long time, even the rest of your life, and never need further endodontic treatment. However, in few cases, a tooth may not heal or may become re-infected. A tooth may become painful or diseased months or even years after successful treatment. If this occurs, root canal surgery may help save your tooth. The most common surgery used to save damaged teeth which have already undergone a root canal procedure is an apicoectomy or root-end resection.

Other reasons for endodontic surgery are for diagnosis, allowing your endodontist to examine the entire root of your tooth, find the problem, and provide treatment, and to treat damaged root surfaces or surrounding bone.

What happens in an apicoectomy procedure?

Performed by an endodontist, the procedure begins with a tiny, minimally-invasive incision which is made to open the gum tissue near the tooth. The endodontist then uses a dental operating surgical microscope and advanced equipment to remove the infected tissue at the very tip of the root.

Once that process is completed, the end of the tooth canal is cleaned and sealed with a small biocompatible filling to prevent re-infection. The gum tissue is then sutured to help the tissue heal properly. Following surgery, the bone will naturally heal around the end of the root and restore the tooth’s full function.

Most endodontic microsurgeries take between 30 to 90 minutes, depending on the location of the tooth and the complexity of the root structure.
