EOTRH - Dental Disease In Horses: Common Causes Symptoms & Treatment

Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) is a dental disease that affects horses. It is a painful condition that can result in tooth loss and significant discomfort for the animal. In this blog post, we will discuss the causes, symptoms, diagnosis, and treatment options for EOTRH in horses.

What Causes EOTRH In Horses?

The exact cause of EOTRH is not yet known. However, it is believed that the condition is caused by a combination of factors, including age, genetics, diet, and environmental factors. Horses over the age of 15 are at higher risk of developing the disease, and it appears to be more common in breeds such as Warmbloods, Draft horses, and Quarter Horses.

Common Symptoms Of EOTRH In Horses

The symptoms of EOTRH can be challenging to detect, as the disease progresses slowly and is often not diagnosed until it is in the advanced stages. Some of the most common symptoms of EOTRH in horses include:

Diagnoses, Treatment, & Prevention Of Dental Disease In Horses


To diagnose EOTRH, a veterinarian will perform a thorough oral examination, including a visual inspection of the horse’s teeth, gums, and mouth. Radiographs may also be taken to evaluate the extent of the disease and determine which teeth are affected. It is essential to catch the disease in its early stages to prevent tooth loss and ensure the horse’s comfort.


The most common treatment for EOTRH is the extraction of affected teeth. This is typically done under sedation and local anesthesia, and the horse will require a period of rest and recovery after the procedure. In some cases, antibiotics or pain medication may be prescribed to manage pain and prevent infection. It is important to note that once a tooth is affected by EOTRH, it cannot be saved, and extraction is the only option.


There is currently no known way to prevent EOTRH in horses. However, maintaining good dental hygiene and scheduling regular dental checkups with a veterinarian can help to detect the disease early and prevent tooth loss.
