The jaw joint is formally known as the temporomandibular joint, or TMJ. When there are problems with the jaw, this is known as TMD, which stands for temporomandibular joint disorder or temporomandibular joint dysfunction.
TMD symptoms are caused by swelling of the jaw muscles that lead to jaw joint problems. The most common symptoms of TMD include jaw popping or clicking, having a hard time opening or closing your mouth, a sore jaw, and even headaches.
TMD treatment can take many forms. Doing jaw exercises and eating soft foods can help relieve TMD pain, and pain relievers can reduce inflammation. A TMD dentist can prescribe a dental guard to wear at night to reduce teeth grinding. The most serious cases may call for TMD injections or TMD surgery.
