Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a progressive dental condition that occurs in some middle-aged and older equines. The disease involves two different cellular processes: 1) resorption/destruction of the tooth by specialized cells (odontoclasts) and 2) a proliferation of irregular cementum (the hard substance on the tooth’s surface that anchors it to the jaw) to try to stabilize the dissolving teeth.
Thoroughbreds and warmbloods over 15 years of age make up about half of the reported cases, but horses from any breed and s*x can be affected.
Subtle changes may include tooth discoloration and inflammation of the gums (which may appear red). Horses may not want to bite down on carrots or other treats, and may have difficulty grazing.
Horses with advanced disease may have difficulty chewing, frequent tooth fractures (incisors and/or canines), and painful, swollen gums. Ulcerations and draining tracts may appear around affected teeth. The base of affected, resorbed teeth may appear bulbous due to the buildup of cementum. Affected horses may exhibit difficulties chewing, bad breath, drooling, head shaking, quidding, and weight loss.
In this particular horse, we ended up having to take all incisors. Even though this may seem extreme, it has improved this horse's quality of life ten-fold!!
