Apicoectomy Explained: Root-End Surgery to Save a Tooth

A guide to apicoectomy, the minor surgical procedure performed to treat persistent infection at the tip of a tooth root when conventional root canal treatment is not enough.

Most severe dental pain comes from the pulp — the nerve and blood supply inside the tooth. Once infection reaches the root tip, painkillers alone cannot settle it.

At a glance

  • An apicoectomy, also called root-end surgery, is a minor surgical procedure in which the very tip of a tooth root, along with any surrounding infected tissue, is removed through a small opening in the gum.
  • Apicoectomy is typically recommended when a tooth continues to show signs of infection on X-ray or ongoing symptoms after conventional root canal treatment has already been attempted, sometimes more than once.
  • The procedure is performed under local anaesthesia and generally takes between thirty minutes to an hour.
  • Healing of the gum typically occurs within one to two weeks, while the underlying bone continues to regenerate gradually over several months.

What Is an Apicoectomy

An apicoectomy, also called root-end surgery, is a minor surgical procedure in which the very tip of a tooth root, along with any surrounding infected tissue, is removed through a small opening in the gum. It is generally considered when a tooth has persistent infection despite having already undergone root canal treatment or re-treatment.

This procedure allows the dentist to access and clean the area directly, and to seal the very end of the root with a special filling material, addressing infection that cannot be reached from inside the tooth through the crown.

Apicoectomy is typically recommended when a tooth continues to show signs of infection on X-ray or ongoing symptoms after conventional root canal treatment has already been attempted, sometimes more than once. It may also be considered when the canal cannot be safely reopened from above due to a crown, post, or calcified canal.

Your dentist will usually take a detailed X-ray or, in some cases, a three-dimensional scan to precisely locate the area of infection and plan the surgical approach before recommending this option.

The Surgical Procedure

The procedure is performed under local anaesthesia and generally takes between thirty minutes to an hour. A small incision is made in the gum near the affected tooth to expose the root tip, the infected tissue is removed, and a few millimetres of the root end are trimmed away.

The canal is then sealed from this end with a biocompatible filling material to prevent bacteria from re-entering, and the gum is closed with a few fine sutures. Most patients experience mild swelling and discomfort for a few days afterwards, which settles with prescribed pain relief and cold compresses.

Recovery and Success Expectations

Healing of the gum typically occurs within one to two weeks, while the underlying bone continues to regenerate gradually over several months. Follow-up X-rays are usually taken at intervals to confirm that healing is progressing as expected.

Apicoectomy has a favourable success rate when performed on a well-selected case with adequate remaining tooth structure, offering a valuable option to save a natural tooth that might otherwise require extraction.

Questions patients ask us

Is apicoectomy a painful procedure?
The procedure is performed under local anaesthesia, so it is not painful during surgery. Mild swelling and soreness afterwards are common for a few days and are effectively managed with the prescribed pain relief medication and cold compresses.
How long does it take to recover from an apicoectomy?
The gum tissue generally heals within one to two weeks, while complete bone healing underneath can take several months. Most patients resume normal activities and eating within a few days, avoiding hard chewing on the treated side initially.
Is apicoectomy an alternative to extraction?
Yes, apicoectomy is often considered as a tooth-saving alternative when conventional root canal re-treatment is not possible or has not resolved the infection, allowing the natural tooth to be retained rather than extracted and replaced.
Will I need a new crown after apicoectomy?
Usually not, since the procedure is performed through the gum rather than through the crown of the tooth. If your existing crown or filling is intact and in good condition, it typically does not need to be replaced after this surgery.
