Temporomandibular Joint Disorder (TMJ) is a condition affecting the jaw joint and surrounding muscles. It can cause pain, discomfort, and difficulty in moving the jaw. Symptoms may include jaw pain, clicking or popping sounds when moving the jaw, and headaches. The exact cause of TMJ can vary and may include factors like jaw injury, arthritis, or teeth grinding. 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 if other treatments are ineffective.
