An apicoectomy is a surgical procedure performed to treat a persistent infection or inflammation at the root tip (apex) of a tooth. When a tooth’s root canal treatment has been unsuccessful or there is a persistent infection, an apicoectomy may be recommended. During the procedure, a small incision is made in the gum tissue near the affected tooth, allowing access to the root tip. The infected or damaged tissue is carefully removed, and the root tip is cleaned and sealed to prevent further infection. The area is then sutured. An apicoectomy is a beneficial treatment option, particularly for a tooth that already has a crown, as it can help save the tooth without the need to remove the crown for retreatment.
