This creates less and less tissue to cushion the bones and, over time, can be reduced to bone-on-bone agitation.” As if the jaw isn’t already complicated enough, add teeth into the equation and that multiplies the complexities of the whole ensemble. And the more someone over-exercises their jaw or grinds their teeth, the more worn down the cartilage becomes. One of our hygienists, Alice, explains it like this, “Just like any other joint needs that cartilage, so does the jaw. One important piece to this intricate puzzle is the Lima bean-sized cartilage nestled between the bones that makes up the joint. Additionally, there are ligaments and tendons in conjunction with nerves and muscles that support the jaw and its movements. It is the only joint in the entire body that is bi-laterally hinged, meaning it moves forward and backward, up and down, and side to side. So just why is this joint such a nuisance? Think about the many ways your jaw moves throughout the day – yawning, chewing and smiling, just to name a few. In fact, many people experience back, shoulder and neck pain as a result of TMJ. The most common points of discomfort associated with TMJ are the temporal lobe and the back of the neck, but are certainly not restricted to these areas. This joint is the most complex joint in the human body, so its dysfunction could only be accompanied by a surpassingly complex pain disorder. That’s what you can feel moving when you open and close your mouth. The temporomandibular joint connects the lower jaw (the mandible) to the skull (temporal bone) and the connection comes together right in front of each ear.
