Root canal treatment is highly successful in saving infected teeth. However, in some cases, infection persists even after a well-performed root canal. When retreatment is not possible or has failed, Apicoectomy, also known as root-end surgery, becomes the preferred option to save the natural tooth.

Apicoectomy is a minor surgical procedure performed by an Oral & Maxillofacial Surgeon to remove infection from the tip of the tooth root and seal it from the root end.

This complete guide explains apicoectomy in clear, patient-friendly language — when it’s needed, how it’s done, recovery, and success rates.

What Is Apicoectomy?

An apicoectomy is a surgical procedure in which:

• The tip of the tooth root (apex) is removed

• Infected tissue around the root is cleaned

• The root end is sealed to prevent reinfection

Instead of accessing the tooth from the crown (as in root canal treatment), apicoectomy treats the infection from the root end through the gum and bone.

Why Is Apicoectomy Needed?

Apicoectomy is recommended when:

• Infection persists after root canal treatment

• Root canal retreatment is not possible

• Complex root anatomy prevents proper cleaning

• Broken instruments are stuck inside the canal

• Post or crown blocks access to the canal

• Cysts or chronic infection form at the root tip

The goal is to save the tooth and avoid extraction.

Common Symptoms Indicating Root-End Infection

You may need apicoectomy if you experience:

• Persistent pain after root canal

• Swelling or pus near the tooth

• Recurrent gum abscess

• Tenderness while biting

• A small pimple-like swelling on the gum

• Infection seen on X-ray despite treatment

Some patients have no pain, but imaging shows ongoing infection.

How Apicoectomy Is Diagnosed?

Diagnosis includes:

1. Clinical Examination

• Checking tenderness, swelling, sinus tract

2. Digital X-ray

• Detects persistent infection at the root tip

3. 3D CBCT Scan

• Shows exact location and size of infection

• Identifies hidden root canals

• Helps plan safe surgical access

CBCT ensures precision and safety, especially near nerves or sinuses.

Apicoectomy vs Root Canal Retreatment

Your surgeon decides the best option based on anatomy and previous treatment.

Step-by-Step Apicoectomy Procedure

Step 1: Anesthesia

Local anesthesia ensures the procedure is painless. Sedation may be used if required.

Step 2: Gum Access

A small incision is made in the gum to expose the underlying bone.

Step 3: Bone Window Creation

Minimal bone is removed to reach the infected root tip.

Step 4: Root-End Removal

The infected portion of the root (usually 2–3 mm) is removed.

Step 5: Cleaning the Infection

All infected tissue and cystic material are thoroughly removed.

Step 6: Root-End Filling

A biocompatible material seals the root end to prevent reinfection.

Step 7: Suturing

The gum is repositioned and sutured.

The procedure typically takes 30–60 minutes.

Is Apicoectomy Painful?

No.The surgery is done under anesthesia, so you won’t feel pain during the procedure.Post-operative discomfort is mild and managed with medications.

Most patients return to normal routine within 1–2 days.

Recovery After Apicoectomy

• Mild swelling for 2–3 days

• Ice packs reduce swelling

• Soft diet recommended initially

• Avoid heavy chewing on the treated side

• Sutures removed or dissolve naturally

Healing of the bone takes several months but happens gradually without discomfort.

Success Rate of Apicoectomy

Modern apicoectomy procedures have a success rate of 85–95%, especially when:

• Proper diagnosis is done

• CBCT-based planning is used

• Biocompatible root-end filling materials are applied

Early treatment improves success significantly.

Risks and Complications (Rare)

• Temporary swelling or bruising

• Mild discomfort

• Infection (rare)

• Temporary numbness (rare)

When performed by an experienced OMFS specialist, complications are minimal.

What Happens If Apicoectomy Is Not Done?

Ignoring persistent infection can lead to:

• Chronic pain

• Spread of infection

• Bone loss

• Abscess formation

• Eventual tooth loss

Apicoectomy allows you to keep your natural tooth instead of extracting it.

Why Choose YOUR DENTIST for Apicoectomy?

• Experienced Oral & Maxillofacial Surgeon

• Advanced CBCT-based diagnosis

• Precise, minimally invasive surgical technique

• Sterile surgical environment

• Focus on tooth preservation

• Careful follow-up and patient education

Saving natural teeth is always our priority.
