Canine Tooth Resorption

A tooth can become resorbed either from the inside of the tooth (internal resorption) or from the outside (external resorption). The exact cause of tooth resorption is unknown.

Recommended Therapy

  • For internally resorbed teeth — Extract the tooth or perform a root canal.
  • Externally resorbed teeth — If the resorption extends to the oral cavity, extract the tooth. If not, monitor the patient closely with periodic clinical and radiographic examinations.
