Endodontic surgery is a minor surgical procedure on the end of the tooth root (apex) and the surrounding tissues. The aim is to remove infected or inflamed tissue so that your tooth can be saved. Endodontic surgery may be used when root canal treatment alone is not enough to save your tooth.
Endodontic surgery may be required to:
Treat infection that cannot be treated by root canal treatment alone.
Treat disease of bone surrounding a tooth.
Take a biopsy to help diagnose disease around a tooth root.
