Temporomandibular joint and muscle disorders, commonly called "TMJ," are a group of conditions that cause pain and dysfunction in the jaw joint and the muscles that control jaw movement. The condition appears to be more common in women than men. For most people, pain in the area of the jaw joint or muscles does not signal a serious problem. Generally, discomfort from these conditions is occasional and temporary, often occurring in cycles. The mainstay of treatment for acute TMJ pain is heat and ice, soft diet, and anti-inflammatory medications. Surgery may also be considered.
