What to expect

1. Re-evaluation

We perform a detailed assessment using CBCT 3D imaging to understand why the original root canal may have failed.

2. Access & removal

Existing filling or decay is carefully removed to access the canals and eliminate residual infection or missed anatomy.

3. Cleaning & disinfection

We use advanced tools—including EdgePRO® laser technology—to clean, disinfect, and shape the canal system with a focus on precision.

4. Filling & sealing

The tooth is sealed again using gutta-percha and a biocompatible sealer to block out future reinfection.

5. Restoration & healing

We coordinate with your general dentist for the final crown or restoration to protect the tooth and restore full function.

A successful retreatment prevents the need for extraction or dental implants.

Root canal didn’t last? We retreat it and make it right

Frequently asked questions

View all

Is root canal retreatment more painful than the first time?

Not at all. With modern anesthesia and sedation, retreatments are typically just as comfortable as the initial procedure. Most patients in our Livingston and Summit offices report only minor post-op soreness.

How long does a retreatment take?

Root canal retreatments usually take 60–90 minutes, depending on the tooth and complexity. Additional time may be needed if previous materials or missed canals are difficult to access.

Why would I need a root canal retreatment?

Common reasons include missed canals, reinfection, a delayed crown placement, or a new fracture. Our CBCT imaging helps us identify what went wrong and target it precisely.

How much does root canal retreatment cost in Livingston or Summit?

Fees vary based on tooth location and complexity. We’ll provide a transparent estimate before treatment and help you navigate insurance or financing options

What are the chances of success with retreatment?

Very high. With advanced tools like EdgePRO® laser cleaning and microscope guidance, retreatment can often save the tooth and relieve symptoms effectively—even when prior treatment failed.

Will I need another crown after retreatment?

In most cases, your general dentist will place a new crown or restore the old one if it’s still in good condition. Protecting the tooth afterward is key to long-term success.

Is it better to retreat or extract the tooth?

Whenever possible, saving your natural tooth is ideal. Retreatment is less invasive, more cost-effective, and avoids the need for an implant or bridge. We’ll help you determine the best option for your case.

What happens if I don’t do anything?

Untreated infection can spread, cause pain, damage the bone, and lead to tooth loss. Early retreatment gives you the best chance at preserving your natural tooth

How soon should I schedule retreatment after symptoms return?

As soon as possible. The longer you wait, the more complicated the infection can become. We offer same-day appointments in Livingston and Summit when urgent pain returns.
