Odontoclastic Resorptive Lesions

In the spirit of dental month here is a fast read on Odontoclastic Resorptive Lesions (ORL)

What is it?

ORL is the reabsorption of the hard parts of your pet’s teeth. The body releases odontoclasts which are special cells that breakdown tooth material. This can happen for many different reasons resulting in 2 types of ORL. Type 1: External ORL. This can be caused by neoplasia (abnormal growth of cells), certain medications like anticonvulsants, or hypoparathyroidism. Type 2: Internal ORL. This is usually caused by trauma.

ORLs usually look like red spots on the tooth’s surface, or inflamed delicate gingival tissue.

Who can get it?

ORL is most common in cats older than 2 years. Usually, it is uncommon in patients under 4-6 but it is still a possibility. With that said, pure breeds have a higher tendency of developing this condition at younger ages. Still, it does not breed, gender or age specific.

Dogs can get ORLs as well but it is less common.
