Fun fact! The mandible is the largest bone of the face and the only bone in your skull that can move. The temporomandibular joint commonly referred to as the TMJ is located below your ears on either side of the head. This complex joint enables a range of motion; helping you speak, chew, swallow, yawn, and move your jaw. The complexity of TMJ anatomy can be a bit daunting. But, when you know the basics of how your temporomandibular joint functions, it may help you better understand how you can keep it in good working order for many years to come.
