Equine Odontoclastic Tooth Resorption and Hypercementosis  (EOTRH)

EOTRH, Equine Odontoclastic Tooth Resorption and Hypercementosis is a painful syndrome that primarily affects the incisors and canine teeth.

This condition has an increased prevalence in older horses (15+ years), Arabian horses, horses with excessive dentistry (incisor reductions), dental disease, not grazing, endocrine diseases, and external and behavioral vices.

The roots of the teeth begin to resorb(dissolve), and the body tries to stabilize the teeth by laying down more cementum. The cause is unknown, and currently the best and only treatment option to surgically remove the teeth.

Clinical signs can include inappetence, salivation/foaming, rinsing of mouth constantly, and reluctance to accept treats. X-rays are necessary for definitive diagnosis for this condition.
