What Can Dental Pain Take From Your Horse?
A couple weeks ago I was asked to look at a younger horse with ongoing riding and handling issues. Slow eater. Very watchy. Head shaking. Nervous and jumpy in the bridle. Multiple bit changes had been tried with no real improvement. As the ride went on, the horse would start rooting, pushing his nose out, and at times bucking. This horse had the best of care and plenty of professional help, yet the issues persisted.
On exam, I found an unhealthy upper left cheek tooth (206). It was cupped out and not erupting normally, while the lower opposing tooth was overgrown and putting constant pressure on it. The vet took X-rays confirmed the tooth was compromised. While floating and balancing were part of the plan, this tooth itself was not healthy and was not going to improve.
Due to the severity of the horse’s issues, the veterinarian elected to extract the tooth. Once removed, the problem was obvious. There were dark defects inside the tooth, and a hypodermic needle could easily be passed into and through part of it. The front half of the tooth looked very different from the back, it was much more radiolucent and gray in the X. Ray ( the picture of the X-ray posted was taken after the tooth was extracted, pretty cool idea from the good doctor.) showing long-term internal damage. Other than addressing the overgrown opposing tooth, and a general balance of the mouth nothing else was done.
Today I spoke with the barn manager. She said "this is not the same horse by any description." Eating faster, calm, soft in the bridle, no nervousness, no resistance.
A good reminder that hidden dental pain or just one bad tooth, even in an otherwise decent mouth can quietly cause big behavioral problems.
