Resorption is a physiologic or pathologic loss of dentin, cementum, and/or bone not immediately due to dental caries or trauma. It can happen spontaneously, or as a result of other factors.


What is resorption?

There are varying forms of dental resorption. Some are natural processes and others are not. Careful attention to the location of resorbing tissue, their clinical and radiographic appearance, and the presence of any etiologic agents can make accurate detection, diagnosis and management all possible.

Leading causes
of resorption

Dental Trauma

Dental trauma can potentially create a break in the protective tissues surrounding your tooth. Without these protective barriers, the tooth can undergo resorption.

Orthodontic treatment

Much like dental trauma, orthodontic treatment has been shown to disrupt the protective barriers surrounding your tooth. Monitoring these areas for any signs of progression is critical to maintaining your natural tooth.


Dental infection can create a loss or damage to the precementum lining the root surface. This combined with inflammation of the adjacent periodontal ligament creates an environment that can be destructive to the existing root structure, resulting in parts of your root being resorbed.


Some cases of resorption have been linked to different viruses. These cases are rare, but are worth noting.

How do we treat resorption?

Resorption is either treated using an Internal or External approach. This depends on the location, type and extent of the resorption. The internal approach involves restoring the resorptive defect from within the tooth. Oftentimes this is done in conjunction with the root canal procedure. The external approach typically requires a separate appointment to gain access to the exterior aspect of the root. The defect is removed and restored similar to a dental cavity.
