TMJ disorders refer to a group of conditions affecting the temporomandibular joint, which connects the jawbone to the skull. These disorders can cause pain in the jaw, face, and neck, as well as difficulty in moving the jaw. Symptoms may include clicking or popping sounds when opening or closing the mouth, headaches, and earaches. The exact cause of TMJ disorders can vary and may include jaw injuries, arthritis, teeth grinding, or stress. Treatment options often involve pain relief methods, physical therapy, or dental appliances to help manage symptoms and improve jaw function. In some cases, surgery may be considered.
