An apicoectomy is surgery at the end of a tooth root. It may be considered when inflammation or infection persists around the root after root canal treatment. The aim is to manage the problem while retaining the tooth, where that is a reasonable option. American Association of Endodontists: endodontic surgery
Does an unsuccessful root canal always need surgery?
No. A tooth may need further assessment, non-surgical retreatment, surgery or extraction, depending on the cause and condition of the tooth. The endodontist considers the existing root filling, restoration, surrounding tissues and whether the tooth can be restored usefully. Symptoms alone cannot determine the choice.
Ask why the proposed option is preferable in your case. Root-end surgery should not be presented as a compulsory final step before extraction.
What happens during an apicoectomy?
The clinician accesses the root end through the gum, removes affected tissue and the root tip, and may place a small root-end filling before closing the site. Local anaesthesia helps control discomfort during the procedure. The details depend on the tooth and anatomy. AAE: how endodontic surgery works
How should you prepare?
Bring your medicine list, medical history and any previous dental records. Mention allergies and previous treatment difficulties. Ask about the anaesthetic plan, eating instructions and whether transport arrangements are needed. Do not change prescribed medicines without the treating clinician’s advice.
Recovery and follow-up
Follow the written instructions for cleaning, eating, medicines and activity. Some soreness or swelling can occur, and healing time varies. Attend the planned reviews so the clinician can assess the site and longer-term healing. AAE: recovery after surgery
Contact the clinic for worsening pain or swelling, persistent bleeding, fever or concerns about the wound. Breathing or swallowing difficulty needs emergency medical assessment; see our dental-emergency guide.
Benefits, limits and questions
The intended benefit is retaining a tooth that may otherwise be lost. Success is not guaranteed, and further treatment or extraction can still be necessary. Ask about the prognosis of the whole tooth, including the crown or filling, rather than the surgical site alone.
