Do you know what is the most persistently used joint in the body? If you answered the temporomandibular joint, then you are correct! Without this joint, which connects the lower jaw with the skull, we would not be able to open our mouths to eat, chew, breath, or talk. It is possible to experience discomfort in this joint as well as near your ears, in your jaws, or in the muscles on the sides of your face. If you are experiencing this discomfort, you might be suffering from TMD.
