The temporomandibular joint is a joint in front of the ear that can move with the opening and closing of the jaw and chewing, called the temporomandibular joint. The normal function of the temporomandibular joint can ensure the free movement of the jaw, the free opening and closing and the completion of the chewing action. The cause of TMJ disorders is often an abnormal occlusal relationship, so it is necessary to go to the dentistry department to find out if there is a cause of abnormal occlusal relationship and to treat it. Temporomandibular joint disorders may occur intermittently, with a popping sound when chewing or painful swelling and discomfort, and may be treated with physical therapy. When there is joint effusion, the joint cavity is treated with long-acting hormone injection. During the acute inflammation period, oral anti-inflammatory drugs can be taken, physical therapy can be done, and avoid biting hard things with the affected side.
