Temporomandibular joint disorder\u2014also called TMJ or TMD\u2014describes a group of conditions that affect the muscles in your jaw. The temporomandibular joint 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, these joints work together so you can do simple, everyday things like chewing your food, speaking to a friend or swallowing your favorite drink.<\/p>\n
TMJ disorders often 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.<\/p>\n
While there is no known cause, TMJ affects millions of Americans. Trauma to the jaw or face usually plays a role in the development of this condition, but these conditions are also believed to contribute to the development of TMJ:<\/p>\n
