The temporomandibular joint (TMJ) is a hinge joint that connects the jawbone to the skull. It allows for movements such as opening and closing the mouth, as well as side-to-side motion. This joint is located on both sides of the head, just in front of the ears, and plays a crucial role in activities like chewing, speaking, and swallowing. TMJ disorders can occur due to various factors, including injury, arthritis, or teeth grinding. Symptoms may include pain in the jaw, difficulty in moving the jaw, and clicking or popping sounds when opening or closing the mouth. Treatment options vary and can include physical therapy, medication, or dental appliances.
