Endodontic Retreatment

Give Your Tooth a Second Chance

If you’ve had a root canal in the past and continue to experience pain or develop new dental issues, endodontic retreatment may offer a second chance to save your tooth.

What Is Endodontic Retreatment?

Endodontic retreatment is a specialized procedure for teeth that have previously undergone root canal therapy but continue to experience issues. Whether it’s lingering pain, a new infection, or a missed canal, retreatment allows our team at Morgan Hill Endodontics to reopen the tooth, thoroughly disinfect the root canal system, and protect your tooth with a fresh seal—helping you avoid extraction and maintain a healthy smile.

When Is Endodontic Retreatment Needed?

Despite successful outcomes for most root canal treatments, some teeth may fail to heal or become re-infected months or even years later. Common reasons for endodontic retreatment include:

  • Missed/Curved Canals: Narrow or hidden canals can go undetected during the initial treatment.

  • New Decay or Damage: A cracked crown, loose filling, or new decay can expose your tooth to bacteria.

  • Incomplete Restoration: Delays in placing a crown or permanent filling may allow re-contamination.

  • Persistent Pain or Infection: Abscesses, swelling, or pain around the treated tooth may signal a problem.

If you notice ongoing discomfort, an endodontic consultation can help determine if retreatment is your best option.

Signs You May Need Endodontic Retreatment

If you’re experiencing any of the following in a tooth that was previously treated with a root canal, endodontic retreatment could be necessary:

  • Persistent tooth pain or sensitivity

  • Ongoing swelling or abscess near the treated tooth

  • New decay or damage exposing the tooth’s interior

  • Changes in how the tooth feels when you bite or chew

What to Expect During Endodontic Retreatment

Endodontic retreatment at Morgan Hill Endodontics typically follows these steps:

  1. Evaluation and Diagnosis: We begin by clinical examination and reviewing X-rays or 3D images to pinpoint problem areas.

  2. Opening the Tooth: Old restorations or filling materials are carefully removed to access the canals.

  3. Cleaning and Disinfection: The canals are thoroughly re-cleaned, removing infection or debris.

  4. Filling and Sealing: We refill and seal the canals with biocompatible materials to protect against future infection.

  5. Temporary Filling: A temporary restoration may be placed until you return to your general dentist for a new crown or permanent filling.

  6. Final Restoration: Your dentist will restore the tooth’s strength and functionality with a permanent crown or filling.

The Difference Between Retreatment and Apicoectomy

When discussing endodontic procedures, you might hear terms like retreatment and apicoectomy. While both aim to preserve your natural teeth and alleviate pain, they are recommended under different circumstances:

  • Retreatment: Focuses on re-cleaning the entire canal system from the top of the tooth, often indicated when original root canal therapy has failed or missed areas of infection.

  • Apicoectomy: A surgical procedure typically considered if retreatment is not sufficient or possible. It involves removing the tip of the tooth’s root (the apex) and sealing the end of the canal.

Your endodontist will help you determine which procedure best addresses your situation.
