Regenerative Endodontic Treatment

What Is Regenerative Endodontic Treatment?

Regenerative endodontic treatment (also called revascularization) is an advanced procedure used primarily for immature permanent teeth whose pulp has become infected or damaged before the root has fully developed.

Unlike a traditional root canal, which removes the pulp and permanently fills the root canals, regenerative endodontic treatment aims to encourage the body's natural healing process. By disinfecting the inside of the tooth and creating conditions that promote new tissue growth, this procedure may allow the root to continue developing, strengthening the tooth over time.

The goal is to preserve the natural tooth while promoting continued root formation and improving the long-term outlook for the tooth.

Why Might I Need Regenerative Endodontic Treatment?

Your endodontist may recommend regenerative endodontic treatment if:

• A young permanent tooth has become infected after an injury or deep decay.
• The pulp inside the tooth has died before the root was fully developed.
• The tooth has an open or immature root tip.
• Continued root development is needed to strengthen the tooth.
• You have swelling, infection, or an abscess associated with the tooth.

In some cases, an immature tooth requiring regenerative treatment may not cause noticeable symptoms and is discovered during a dental examination or X-ray.

What Happens During Regenerative Endodontic Treatment?

Regenerative endodontic treatment is typically completed over two or more visits.

1. Examination and Preparation

Your endodontist will examine the tooth and take X-rays or a CBCT scan to evaluate the stage of root development and the extent of the infection. Local anesthesia is used to keep you comfortable throughout the procedure.

2. Cleaning and Disinfecting the Tooth

A small opening is made in the tooth, and the root canal is gently cleaned and disinfected to remove bacteria while preserving the fragile root structure. A special medicament may be placed inside the tooth to eliminate any remaining infection, and the tooth is sealed with a temporary filling.

3. Stimulating New Tissue Growth

At a follow-up visit, once the infection has resolved, your endodontist will encourage gentle bleeding into the root canal space. The blood clot serves as a natural scaffold that supports healing and may encourage the growth of new tissue within the root canal.

4. Sealing the Tooth

A biocompatible material is placed over the blood clot to protect the developing tissue, and the tooth is sealed with permanent restoration to prevent future contamination.

5. Monitoring Healing and Root Development

Regular follow-up appointments are essential. Your endodontist will take periodic X-rays to monitor healing, continued root development, thickening of the root walls, and closure of the root tip. These changes help strengthen the tooth and improve its long-term prognosis.

Does Regenerative Endodontic Treatment Hurt?

Regenerative endodontic treatment is designed to be comfortable. Local anesthesia is used during the procedure, and most patients experience little discomfort. Mild soreness after treatment is normal and usually resolves within a few days.

Protecting Your Regenerated Tooth

A tooth treated with regenerative endodontics can continue to develop and function successfully with proper care. Maintaining excellent oral hygiene, attending regular dental checkups, and keeping all scheduled follow-up visits are essential to monitor healing and root development. Avoid biting on hard objects with the treated tooth until your endodontist advises that it has fully healed. With proper care, regenerative endodontic treatment can help preserve your natural tooth and promote healthy root development for years to come.
