When is Root Canal Retreatment Recommended?

You thought it was behind you—the discomfort you felt when you had an infected root canal system. And for a while, it was. But now it’s back and you’re wondering what happened and what to do about it.

Sometimes a tooth that has been through root canal therapy doesn’t heal properly. And you may not know it until you experience symptoms of a failed root canal months or even years after the initial treatment.*

There are several reasons why the healing process didn’t happen as expected. Parts of the root canal system may not have been detected and treated during the first treatment, which can happen with complex root canal anatomy. Perhaps the placement of the crown or filling didn’t prevent new bacteria from entering the tooth. Or maybe you sustained new damage to the tooth.* Whatever the reason, you may need root canal retreatment to save your tooth.

What is Root Canal Retreatment?

GentleWave ProcedureSimply stated, root canal retreatment is treating a tooth for the second time or more with root canal therapy. Root canal retreatment may be a bit more complex than your first treatment. That’s because in some cases, restorative materials (such as a crown and core material) must be carefully removed before the cleaning and disinfection can begin.* If the canals are unusually narrow or blocked, your dentist or endodontist may need more time to regain access to those canals and remove the infection, or they may recommend endodontic surgery to seal the end of the root to help prevent reinfection.*

Decrease your Chance of Needing Root Canal Retreatment

Of course, the best way to minimize the chance you’ll need root canal retreatment is to ensure that the infected tissue and debris is effectively removed during the first treatment—which is precisely what the GentleWave® Procedure was designed to do. It maximizes cleaning and disinfection using advanced fluid dynamics to create a vortex of procedure fluids that travel through root canal system. Along the way, broad spectrum acoustic energy helps remove the tissue and debris that cause infection.1,2 This means fewer files may be used with GentleWave Procedure than standard root canal treatment.

But if you have experienced a failed root canal and require root canal retreatment, the GentleWave Procedure is an option as it reaches into microscopic spaces1,2 that standard root canal treatment frequently cannot.3 This helps to ensure that your infected tooth is cleaned efficiently.1

Plus, in most cases, the GentleWave Procedure can be completed in just one session,4—and that’s a great benefit, especially if you’ve already gone through root canal therapy.
