TMJ is the dysfunction of the the temporomandibular joint, which connects your jaw to the temporal bones of your skull. The temporo-mandibular joint (TMJ) is used on an everyday basis for eating and talking, and can become worn down due to excessive teeth grinding. Unfortunately, teeth grinding can lead to severe tension headaches and sharp pain in the jaw. Millions of people suffer a temporomandibular joint disorder (TMD) all over the world. Unfortunately, many cases are left untreated or only partially treated. Myofacial TMD is a specific type that is associated with the pain from hyperfunctioning muscles from everyday activities, like chewing. Myofacial TMD can even lead to chronic myositis. Therefore, if you have TMD, it is imperative to seek help right away so that you no longer have to live with persistent, even chronic pain.
