Persistent infection after a root canal?

Expert Endodontic Surgery (Apicoectomy) in Annandale

What is an Apicoectomy procedure?

Root canal therapy is often the most effective way to treat infection inside a tooth. However, in certain cases, infection around the root tip may require a more targeted surgical approach.

An apicoectomy — also known as root-end surgery — is a precise microsurgical procedure that removes the infected tissue at the tip of the root and seals the end of the canal. This helps the surrounding bone heal properly, prevents reinfection, and allows you to preserve your natural tooth.

At Prestige Dental Specialists in Annandale, we perform advanced endodontic microsurgery using 3D imaging, surgical microscopes, and modern biocompatible materials. Our approach is designed for accuracy, comfort, and long-term success — helping you maintain your natural smile whenever possible.

Why you might need root canal surgery

Persistent infection

If bacteria remain after root canal treatment or re-enter through a crack or compromised restoration, infection may continue to persist at the tip of the root.

Ongoing symptoms despite imaging

Occasionally, patients may continue to experience discomfort or swelling even when imaging does not clearly show the source of the problem. Apical surgery allows the doctor to directly access the root tip and surrounding tissue to locate and treat the affected area.

Blocked or calcified canals

Over time, calcium deposits can narrow the root canals, making it difficult for instruments to reach the tip of the root during conventional treatment.

Complex root anatomy

Some teeth have curved roots, extra canals, or unique internal structures that can make complete cleaning challenging. Root-end surgery allows the specialist to directly address the area at the root tip.

Obstructions or hidden anatomy

Posts, separated instruments, or previously undetected canals may limit access during retreatment. In these cases, surgery can provide a more direct approach while preserving the existing restoration.

Is an apicoectomy painful?

Modern endodontic microsurgery is comfortable, and many patients are surprised by how little discomfort there is after surgery.

You may experience:

Mild tenderness or pressure for a few days
Slight swelling near the treated area
Temporary bruising in the gum tissue
Manageable discomfort controlled with over-the-counter medication

With today’s techniques and advanced surgical equipment, most patients return to normal routines within a day or two.

What happens during an apicoectomy

Step 1: Precise Access

A small opening is made in the gum tissue near the affected tooth to allow access to the root tip and surrounding area.

Step 2: Removal of Infection

The infected tissue and a small portion of the root tip are carefully removed.

Step 3: Root-End Seal

A biocompatible filling material is placed at the end of the root canal to seal it from future bacterial invasion.

Step 4: Healing

The area is sutured, and the surrounding bone begins to heal naturally over time. Sometimes, bone grafting and/or PRF may be used to promote healing.

This microsurgical approach eliminates infection at its source while preserving the rest of the tooth structure.

The Curious Corner

What is the difference between a root canal and an apicoectomy?

A traditional root canal treats infection from inside the tooth by cleaning and sealing the canals. An apicoectomy treats infection by surgically removing the tip of the root and the surrounding infected tissue. This procedure may be recommended when conventional treatment cannot fully resolve the issue.

Is root canal surgery painful?

Modern techniques, local anesthesia, and sedation options make the procedure very manageable. Most patients describe post-operative discomfort as mild and short-lived.

How successful is an apicoectomy in our Annandale office?

When performed by our specialists using magnification and advanced imaging, root canal surgery has a high success rate. Proper case selection and precise technique play an important role in long-term healing and the preservation of the natural tooth.

What happens if I don’t treat the infection?

If left untreated, the infection can continue to spread, potentially leading to bone loss, swelling, and eventual tooth loss. In some cases, the infection may also affect surrounding tissues and teeth. Early treatment greatly improves the chances of a successful outcome and overall health.

Is extraction a better option?

Extraction is sometimes necessary, but it should be considered carefully. There are several ways to replace a missing tooth, including options such as a dental implant, bridge, or removable appliance. Whenever possible, preserving your natural tooth is typically the healthiest and most cost-effective long-term solution.
