I know I have been banging on about dental work for a few weeks now, but having had two dental procedures myself recently, aswell as the pony having had work done, it is fresh in my head!
I am sitting here with a numb face and a bit of a headache. None of my dental work was painful, but the strain on my jaw and jaw joints ( TMJ’s) was not inconsiderable.
Research , of which there is not much, confirms that TMJ pain in horses is often overlooked, but is a significant cause of performance issues and general discomfort. Post mortem studies and imaging have shown that over 30% of horses have arthritic changes in their temperimandibular joints.
It is definitely important to treat your horse cranially after dental work, as some struggle more than others with having their mouth wide open for periods of time.
But it pales into insignificance to other causes of TMJ pain, particularly our obsession in the horse world to ride with a fixed hand, ride behind the vertical, to demand that the horse “softens” to our vice like grip. This is repetitive strain, and causes a rapid deterioration in any joint, but especially the jaw joint, as the horse opens its mouth to avoid the awful pressure and pain, and even if we strap the mouth shut to avoid the gaping, the tension and pain are still present.
Of course there are other causes of head pain and TMJ issues such as dental abnormalities, poorly fitting tack, secondary issues such as back or hind limb pain, and direct trauma.
Repetitive strain will cause many problems beyond the initial TMJ breakdown, as the hyoid will also be involved, the atlanto-occipital joints ( poll) and certainly C1 and C2, if not all of the cervical joints and beyond, as the pain and trauma cause a domino effect throughout the body.
Most horses are crying out for some form of cranial release, and are very grateful for it. I have plenty of self help exercises for this area, and so many herb oils that will help soothe and soften.
