**An apicoectomy is a minor surgical procedure that removes the very tip of a tooth root, along with any surrounding infected tissue, to save a tooth when a previous root canal has not fully healed.** Also called root-end surgery or an apicectomy, it is usually carried out by an endodontist or oral surgeon under local anaesthetic. It is considered when infection lingers at the root tip and a standard root canal or retreatment cannot resolve it, offering a way to keep your natural tooth rather than extract it.

Hearing that a tooth still has a problem after root canal treatment can be disheartening, especially if you assumed the matter was settled. The reassuring point is that a persistent infection at the root tip does not automatically mean the tooth is lost. An apicoectomy is a well-established, predictable procedure that targets the small area of trouble directly, from the side of the root rather than from the crown of the tooth. This guide explains what the surgery involves, who tends to need it, how it is done, and what recovery and outcomes realistically look like.

## What is an apicoectomy?

An apicoectomy is a small operation that removes the apex, or tip, of a tooth root and the infected tissue around it. The end of the root canal is then cleaned and sealed with a tiny filling. It treats infection that remains after a root canal, allowing the tooth to be kept rather than removed.

To understand why the procedure exists, it helps to picture how a root canal works. Conventional root canal treatment cleans and fills the canals from the top of the tooth, working downwards towards the root tip. Occasionally, infection or inflammation persists at the very end of the root, in an area that the original treatment could not fully reach or seal, sometimes because of complex canal anatomy or a tiny crack. An apicoectomy approaches this same trouble spot from a different direction, accessing the root tip through the gum so the problem can be dealt with at its source.

The procedure is sometimes referred to as root-end surgery, root-end resection, apical surgery or an apicectomy. They all describe the same essential idea: removing the diseased root tip and sealing the canal from the end.

## When is an apicoectomy needed?

An apicoectomy is usually recommended when infection persists at the root tip after a root canal, and a non-surgical retreatment is not possible or has already failed. It may also be needed when a tooth has a crown, post or complex root shape that makes conventional retreatment difficult or risky.

In most cases, surgery is not the first option. If a root canal does not heal, the usual next step is non-surgical retreatment, where the original filling is removed and the canals are cleaned and sealed again. Our guide on [root canal retreatment when a root canal fails](/blog/root-canal-retreatment/) explains that approach in detail. An apicoectomy is typically considered only when retreatment is unlikely to succeed or has not resolved the problem. Common reasons a dentist may suggest it include the following:

 - **Persistent infection at the root tip.** A small area of inflammation or infection, sometimes appearing as a shadow on an X-ray, remains despite previous treatment.
 - **A restored tooth that is hard to retreat.** Removing a well-fitted crown, bridge or post to access the canals could damage the tooth, so surgery from the root end is gentler on the existing work.
 - **Complex or blocked canals.** Curved, narrow or calcified canals, or a fractured instrument left from earlier treatment, can prevent conventional cleaning from reaching the tip.
 - **A cyst or lesion at the root.** Tissue around the root tip may need to be removed and, in some cases, examined to confirm the diagnosis.

If the tooth cannot realistically be saved, the alternative is removal, after which replacement options would be discussed. Our overview of [tooth extraction aftercare and recovery](/blog/tooth-extraction-aftercare/) outlines what that path involves, though the aim of an apicoectomy is precisely to avoid it where possible.

## How is an apicoectomy performed?

An apicoectomy is done under local anaesthetic in a single visit, usually lasting between thirty and ninety minutes. The dentist makes a small opening in the gum to reach the root tip, removes the infected tissue and the end of the root, seals the canal with a small filling, and closes the gum with a few stitches.

The procedure is precise and, thanks to local anaesthetic, should not be painful at the time, though you will feel some pressure. Many endodontists use magnification and good lighting to work accurately on the small structures involved. While each case differs, the steps generally follow this pattern:

 - **Numbing the area.** Local anaesthetic is applied so the tooth and surrounding gum are fully numb before any work begins.
 - **Accessing the root tip.** A small incision is made in the gum near the affected tooth, and the tissue is gently lifted to expose the underlying bone and root end.
 - **Removing infection and the root tip.** The infected or inflamed tissue is cleared away, and a few millimetres of the root tip are removed.
 - **Sealing the canal.** The end of the canal is cleaned and sealed with a small, biocompatible filling to prevent further infection.
 - **Closing the gum.** The gum is repositioned and secured with a few stitches, which are usually removed after several days, or may dissolve on their own.

In the weeks and months that follow, the bone around the treated root tip gradually heals and fills in. Your dentist will normally arrange a follow-up, and sometimes a later X-ray, to confirm that healing is progressing as expected.

## What is recovery from an apicoectomy like?

Recovery from an apicoectomy is usually straightforward. Mild swelling, bruising and tenderness for a few days are normal and generally managed with over-the-counter pain relief. Most people return to everyday activities within a day or two, while the gum and underlying bone continue to heal over the following weeks.

Following your dentist's aftercare advice closely gives the area the best chance to settle and heal cleanly. Typical guidance includes the following:

 - **Manage swelling early.** A cold compress against the cheek for short periods on the first day can help reduce swelling and bruising.
 - **Take pain relief as directed.** Over-the-counter painkillers, used strictly according to the packet instructions, usually keep any discomfort manageable.
 - **Eat gently.** Choose soft foods and avoid chewing directly on the treated side until it feels comfortable.
 - **Protect the surgical site.** Avoid vigorous rinsing, brushing the area too hard, or disturbing the stitches in the first few days.
 - **Keep the mouth clean.** Gentle salt-water rinses, once your dentist advises, help keep the area clean while it heals.
 - **Watch for warning signs.** Increasing pain, swelling or any discharge after the first few days should be reported to your dentist.

Persistent infection that reaches this stage can occasionally point to a wider problem, such as a hidden crack. If the tooth was painful or swollen beforehand, you may find our guide on dental abscess causes, symptoms and treatment a useful companion read, as the same underlying infection is often what an apicoectomy is designed to resolve.

## What are the risks and success rates of an apicoectomy?

An apicoectomy has high long-term success rates and is generally low risk, but no procedure can be guaranteed. Possible risks include continued or recurrent infection, temporary numbness if a nerve is nearby, and, rarely, the need for extraction if the tooth does not heal. Your dentist will weigh these against the alternatives.

For a tooth that would otherwise be lost, root-end surgery is often a sound, conservative choice, and studies suggest most treated teeth heal well and remain functional for many years. That said, an honest picture includes the limitations as well as the benefits. Factors that influence the outcome include the extent of the original infection, the position and anatomy of the root, the presence of any cracks, and how well the area heals afterwards. Where a fracture runs through the root, for example, surgery may not be enough to save the tooth.

> An apicoectomy is best understood as a focused attempt to save a tooth that has already had root canal treatment, not a guarantee. The goal is to give a natural tooth the strongest realistic chance of being kept, and an endodontist can advise whether it is the right option for your particular case.

If you are weighing up your options, the most useful step is a thorough assessment, including up-to-date X-rays, by a clinician experienced in this kind of surgery. They can explain what is realistically achievable for your tooth, what the alternatives would involve, and which path is most likely to give you a lasting, comfortable result. Keeping your own tooth, where it is sensible to do so, remains one of the best outcomes in dentistry.
