A closer look: Dental Disease in Horses
Many of the potential predisposing factors for dental disease can also result from dental disease, including loose or missing teeth, fractured teeth, and abnormal dental wear. Determining which condition occurred first is often not possible. For these reasons, dental disease is often considered progressive, as changes in oral health increases the risk of developing dental disease elsewhere in the mouth.
For under saddle horses, dental disease can cause pain while the horse is bridled.
In some cases, dental disease can lead to tooth root abscesses.
Dental disease is common in horses, particularly in older and senior horses whose teeth are reaching the end of their lifespan. These horses are more likely to develop gaps or pockets between their teeth that collect feed and bacteria, increasing their risk of dental disease. Horses showing symptoms of dental disease require prompt veterinary examination, as significant weight loss can occur due to the pain associated with eating.
Dental disease in horses is typically the result of abnormal dental wear, resulting in spaces or gaps between the teeth that can accumulate feed material. The feed stuck in these gaps rapidly ferments and grows bacteria, resulting in damage to the tooth, the ligaments holding the tooth in place, and the gums surrounding the tooth.
Symptoms of dental disease are often related to pain during chewing.
Testing and diagnosis
Diagnosis of dental disease primarily relies on a physical examination and oral examination. Horses require sedation for a thorough evaluation of the mouth. Other diagnostics may include:
- Diagnostic imaging, including skull X-rays
Steps to Recovery
Treatment typically involves managing the underlying condition, and removing any severely affected teeth. Treatments include:
- Dental flotation: a procedure to reshape the teeth
- Removal of packed in feed material
- Antibacterial rinses of the mouth
- Antibiotic treatment
- Extraction of affected teeth
- Changing the diet to improve feed intake
- Increasing forage in the diet to improve tooth wearing
Dental disease is generally considered progressive, with no definitive cure. Through management and regular dental examination, most horses can have a good quality of life without oral pain. Due to the progressive nature of dental disease, affected horses often require more dental examinations than the average horse. Frequent visits are recommended to identify any new oral problems early, allowing for more effective treatment.
The risk of dental disease can be reduced by routine oral examination by a veterinarian to identify any abnormalities or predisposing risk factors early. Horses require an oral examination at least once per year, unless otherwise recommended by a veterinarian.
Dental disease is not contagious.
