What Is Root Canal Re-treatment?

Root canal re-treatment involves reopening a tooth that has already had root canal therapy, removing the previous filling material, re-cleaning and disinfecting the canals, and resealing them. This procedure is performed when the initial treatment has not fully resolved the infection or when new problems have developed.

Why Might Re-treatment Be Needed?

Persistent Infection

The original treatment did not eliminate all bacteria, or infection persisted in complex canal anatomy.

New Decay or Damage

New decay has exposed the root canal filling to bacteria, or the tooth has cracked allowing recontamination.

Delayed Restoration

If a crown was not placed promptly after root canal, the temporary filling may have leaked.

Missed Canals

Some teeth have extra or hidden canals that were not treated during the original procedure.

Signs You May Need Re-treatment

  • Pain or discomfort – In a previously treated tooth
  • Swelling – Around the tooth or in nearby gum tissue
  • Sensitivity – To pressure or temperature
  • Sinus problems – Persistent issues related to upper back teeth
  • Visible infection – Pimple-like bump on the gum (fistula)
  • X-ray findings – Showing infection at the root tip

The Re-treatment Process

Step What Happens
1. Assessment X-rays and examination to evaluate the previous treatment and current infection.
2. Access The crown or filling is removed to access the root canal filling material.
3. Removal Previous filling material (gutta-percha) is carefully removed from the canals.

Frequently Asked Questions

Why would a root canal need re-treatment?

Re-treatment may be needed if the original treatment did not fully eliminate infection, new decay developed, the crown leaked, or a canal was missed. Sometimes infection returns years after successful treatment.

Is root canal re-treatment more painful?

No, re-treatment is performed under local anaesthesia just like the original procedure. You should not feel pain during treatment. Some tenderness afterward is normal.

How successful is root canal re-treatment?

Re-treatment has a success rate of 75-90% depending on the case. It gives your tooth another chance before considering extraction and replacement.

Why does re-treatment cost more?

Re-treatment is more complex because the dentist must remove the existing filling material, locate all canals, and deal with any complications from the previous treatment.

What are the alternatives to re-treatment?

Alternatives include apicoectomy (surgical root canal) or extraction followed by implant or bridge. Re-treatment is usually tried first as it is less invasive.
