The temporomandibular joints connect the jaw (mandible) to the skull. It is the most active joint in the horse’s body, moving on average 25,000 times per day – or 9 million chews per year. It has evolved over the horse’s evolution to be a sturdy yet flexible joint.
Horse owners often define the TM joints as a condition rather than a joint. For example, my horse has “TMJ,” which describes a syndrome that may not involve the joint. Rather, the connective tissues may give rise to pain. But is this true? Could there be pain located elsewhere that is causing a secondary discomfort in the general area of these joints?
This podcast discusses my experience with tens of thousands of horses and what I have found in my observations, and I compare this to what others say about “TMJ” in horses.
