Getting to Know EOTRH
Dental care is essential to our horses’ well-being—healthy teeth ensure horses can grasp and chew food properly and tolerate a bit when ridden. The most common sources of dental pain are the molars (cheek teeth) that wear into sharp points, long hooks, and ramps as they grow. But veterinarians are now learning that the front teeth—the incisors and canines—are also prone to pain. A relatively newly named dental disease is responsible, sometimes causing severe consequences.
What Is It?

ACVD EQ, of Equine Dental Services of New Jersey, in Morganville. “This does not mean that it must be a new disease. We know that there are similar poorly understood dental conditions reported in humans (multiple idiopathic root resorption) and in cats (feline odontoclastic resorptive lesions). The disease process that we call EOTRH has probably been with horses throughout history.”
He theorizes that veterinarians are recognizing the disease now because horses are living much longer than in the past and veterinarians are scrutinizing their mouths more
