what is tmj disorder

Temporomandibular joint (TMJ) disorder, also known as temporomandibular disorder (TMD), is a condition that causes pain and dysfunction in the jaw joint and the muscles that control jaw movement. The TMJ is the joint that connects your jawbone to your skull and allows for movements like chewing and speaking. TMJ disorders can be caused by various factors, including teeth grinding, jaw injuries, arthritis, and everyday wear and tear. The exact cause of a person's TMJ disorder is often difficult to determine and may be a result of a combination of factors such as genetics, arthritis, or jaw injury. Symptoms of TMJ disorders may include jaw pain, headaches, and difficulty opening and closing the mouth. Treatment varies and may include self-managed care, medication, physical therapy, custom mouth guards, and in some cases, jaw surgery
