An apicoectomy is a form of endodontic microsurgery used to treat persistent inflammation or infection around the tip of a tooth’s root.

During the procedure, a small opening is made in the gum tissue to access the area around the root. The inflamed tissue and a small portion of the root tip are removed, and the end of the root is carefully prepared and sealed.

The goal is to treat the source of the problem while preserving the natural tooth whenever possible.

Endodontic surgery may be recommended when a tooth has persistent disease after previous root canal treatment and the source of the problem cannot be predictably addressed through nonsurgical treatment alone.

Common reasons surgery may be considered include:

• Persistent inflammation or infection around the root tip

• Complex root anatomy that cannot be treated from inside the tooth

• A blockage or obstruction within the root canal system

• Certain procedural complications

• A restoration, post, or other factor that makes nonsurgical retreatment less practical

• The need to directly evaluate the root surface or surrounding tissues

A complete evaluation, including clinical testing and 3D imaging, helps determine whether surgery, root canal retreatment, or another approach is most appropriate.

The area is thoroughly numbed with local anesthesia before treatment begins. A small incision is made in the gum tissue to access the bone surrounding the affected root.

The inflamed or infected tissue is removed, along with a small portion of the root tip. The end of the root is then examined under magnification, prepared, and sealed with a biocompatible material.

The gum tissue is repositioned and sutured, allowing the surrounding bone and tissues to heal over time.

Modern endodontic surgery is performed very differently from traditional root-end surgery of the past.

Today, microsurgical techniques use high magnification, illumination, ultrasonic instruments, and biocompatible root-end filling materials to allow treatment to be performed with greater precision and minimal disruption to the surrounding tissues.

3D CBCT imaging is used before surgery to evaluate the root anatomy, location of the lesion, surrounding bone, and nearby anatomical structures. This information can help guide treatment planning and determine whether surgery is the best option.

Some swelling, tenderness, and mild bruising are normal during the first few days after endodontic surgery. Discomfort is typically manageable with appropriate pain medication and gradually improves as the tissues heal.

Patients are given detailed postoperative instructions regarding oral hygiene, diet, activity, and care of the surgical area. Sutures are typically removed at a short follow-up visit, and additional healing evaluations may be recommended over time to monitor bone healing around the root.

Most patients are able to return to normal daily activities relatively quickly, although strenuous physical activity should be limited during the early healing period.

Both root canal retreatment and apicoectomy are used to treat teeth that have developed persistent problems after previous root canal treatment, but they approach the problem differently.

Retreatment addresses the root canal system from inside the tooth. The previous filling material is removed so the canals can be reevaluated, cleaned, disinfected, and sealed again.

An apicoectomy approaches the problem from outside the tooth and directly treats the tissues and root tip where persistent disease is located.

Neither option is automatically better. The most appropriate treatment depends on the reason the tooth has not healed, the existing restoration, root anatomy, previous treatment, and overall prognosis of the tooth.

After evaluating the tooth and reviewing the imaging, Dr. Safi will explain the available options and recommend the approach that offers the most predictable opportunity to preserve the tooth.
