Temporomandibular Joint Disorders (TMD)
Temporomandibular joint disorder (TMD) describes a group of conditions affecting the muscles in your jaw. The temporomandibular joint (TMJ) is the main cause of pain in these cases. These joints connect the lower jaw (mandible) to the skull. Located on each side of your head, the TMJs work together so you can do simple, everyday things like chewing your food, speaking to a friend or swallowing your favorite drink.
What is TMD?
TMJ disorders cause tenderness in the jaw, facial pain and difficulty moving the joint. You may also notice a clicking, grating, and/or popping noise when you move your jaw. Others may experience lockjaw or difficulty opening their mouth all the way.
