Root Resorption

What is Root Resorption?

Resorption is an inflammatory process which results in breakdown and absorption of tooth structures. This can result in I cavity within a tooth or on the surface of the roots. Although this is a rare phenomenon in adults, root resorption in children is natural and enables the roots of baby teeth to dissolve so that permanent teeth can serve as replacements.

Why Does Resorption Happen in Adults?

We often do not know the cause of root resorption in permanent teeth, but there are several factors which could act as contributors. Pressure and tension are normal stressors that can lead to breakdown in tissue, so years after excessive orthodontic force, a tooth may experience resorption. Likewise, trauma to a tooth may damage gum ligaments, resulting in the beginnings of resorption. Extreme teeth grinding and tooth-bleaching have been found to initiate resorption as well. The good news? Most patients with these risk factors never go on to develop any indicators of root resorption.

What Does Root Resorption Look Like?

It is most common for root resorption to begin on the outside of a tooth near the gum line and work its way inward in a process called external cervical resorption (ECR). Pink spots are a common indicator that ECR is taking place. The eventual effects appear as holes, or cavity-like areas, at the gum line of the tooth.

Not nearly as common as ECR, internal resorption begins in the root of the tooth and is often due to chronic pulp inflammation. Because resorption is usually asymptomatic, most patients are unaware of their condition until well into the resorption process.

How is Root Resorption Treated?

The inflamed tissue that causes resorption can be quite aggressive so it is important to treat resorption as soon as you are made aware of it. Depending on the location and extent of the resorption, it may be managed with a root canal treatment alone or a combination of nonsurgical and surgical root canal treatment. This is an area of Endodontics where CBCT and the Surgical Operating Microscopes have made diagnosis and treatment more reliable and predictable.

Since resorption is usually asymptomatic, detecting its presence in the initial stages isn’t always easy. Nonetheless, early treatment is crucial when it comes to saving the tooth, and as endodontists, our primary concern is to save your natural teeth. Call us at the first sign of root decay or resorption, so we can safely and gently provide you with the best possible care for maintaining your oral health well into the future.

Is Root Resorption Painful?

Surprisingly, no. Root resorption is generally asymptomatic. If you are experiencing pain, another cause is the culprit, and we encourage you to call us today to schedule a consultation. Advanced Endodontics Phone Number (905) 632-3456
