What Is Apical Resection?

Apical resection (apicoectomy) is a minor dental surgery that removes infected tissue and a small portion of the root tip when a tooth still has inflammation after root canal treatment. By sealing the end of the root and clearing the infection, the procedure can preserve the natural tooth and protect nearby bone and gums.

Meta Description: Learn what apical resection (apicoectomy) is, why it’s done after a failed root canal, how the surgery works, key benefits and risks, and what to expect during recovery and follow-up care.

What is apical resection?

Apical resection is a surgical endodontic procedure used to treat infection at the tip of a tooth root. It’s most often recommended when root canal treatment has already been completed, but the root-end area still shows persistent inflammation, pain, or a recurring abscess. The aim is straightforward: remove the infected tissue and seal the root tip so bacteria can’t keep leaking into the surrounding bone.

Dentists may also call this procedure an apicoectomy. With modern imaging and magnification, it can be carried out with high precision, which improves comfort and predictability for many patients.

When is apical resection recommended?

Your dentist or oral and maxillofacial surgeon may suggest apical resection when non-surgical options aren’t likely to solve the problem. This usually happens after a root canal that cannot be retreated effectively, or when the root anatomy and existing restorations make retreatment risky.

Common reasons include

• A persistent infection or cyst at the root tip after root canal treatment
• Blocked canals (for example, from a post, calcification, or complex anatomy) that prevent adequate retreatment
• A fracture or small defect near the root end that needs direct access
• A root filling that cannot be cleaned or replaced without damaging a crown or bridge
• A desire to keep the natural tooth when extraction is the main alternative

How the procedure is performed

Apical resection is typically done under local anesthesia. After numbing the area, the clinician makes a small incision in the gum and creates a window in the bone to reach the root tip. Inflamed tissue is removed, and a small portion of the root end is trimmed.

The end of the root is then cleaned and sealed with a biocompatible filling material to reduce the chance of reinfection. Finally, the gum is stitched back in place. Most appointments take about 30–60 minutes, depending on which tooth is treated and how complex the root structure is.

Benefits of apical resection

The main advantage is tooth preservation. Keeping your natural tooth can support chewing function, bite stability, and appearance—especially in the front of the mouth. For many patients, apical resection provides a practical “second chance” for a tooth that would otherwise be removed.

Key benefits

• Avoids extraction in suitable cases
• Stops infection from spreading into surrounding bone and tissues
• Can relieve ongoing pain, swelling, or recurrent gum boils
• Often faster and less invasive than replacing the tooth with an implant or bridge
• Helps maintain natural aesthetics and normal bite forces

Risks and possible complications

Like any surgical procedure, apical resection has potential risks. Most are uncommon and manageable, especially when the case is well planned and postoperative instructions are followed.

Possible complications

• Temporary pain, swelling, bruising, or mild bleeding in the first few days
• Infection or delayed healing
• Numbness or tingling (rare), depending on the tooth and nearby nerves
• Sinus involvement when upper back teeth are treated (uncommon)
• Failure to resolve the infection, which may still lead to extraction

Recovery and aftercare

Most patients return to normal routines within a day or two, but the surgical site needs time to heal. Discomfort is usually mild to moderate and can be managed with the medications your clinician recommends. Stitches are commonly removed about 7–10 days after the procedure, unless dissolvable sutures are used.

Practical tips for a smoother recovery

• Use an ice pack for the first 24 hours (10–15 minutes on, then off) to help limit swelling
• Choose soft foods and avoid chewing on the treated side for a few days
• Brush and floss normally, but be gentle around the incision
• Avoid smoking and alcohol while healing, as they can slow recovery
• Take prescribed antibiotics or pain relievers exactly as directed

Contact your dental office if you have heavy bleeding, worsening swelling after the first couple of days, fever, or pain that isn’t improving.

Apical resection vs. extraction

Apical resection is usually considered when the tooth can still be saved and has enough healthy structure to function long term. If the tooth is cracked below the gum line, has severe bone loss, or cannot be restored properly, extraction may be the safer choice. Your clinician will weigh prognosis, costs, timeline, and your overall oral health before recommending the best option.

Frequently asked questions

Is apical resection painful?

The surgery itself is performed under local anesthesia, so you shouldn’t feel pain during the procedure. Soreness afterward is common and typically improves over a few days with appropriate pain relief.

How long does apical resection take?

Most procedures take 30–60 minutes, though complex roots or difficult access can extend the appointment.

How long does healing take?

Initial gum healing usually happens within 7–10 days. Bone healing around the root tip takes longer and is monitored at follow-up visits, often with X-rays.

Can any tooth have apical resection?

Not always. Accessibility, root shape, proximity to nerves or the sinus, and the tooth’s overall restorability all affect suitability. A clinical exam and imaging are needed to confirm whether it’s a good option.

What’s the success rate?

Many cases do well when the tooth is properly selected and the root end can be sealed effectively. Your dentist can give a realistic prognosis based on the tooth involved, existing restoration, and the size of the lesion.
