Temporomandibular Joint Disorder
Also known as: TMJ, TMD, TMJ dysfunction
Temporomandibular joint disorder encompasses a group of conditions affecting the jaw joint and the muscles controlling jaw movement. Symptoms include jaw pain, difficulty chewing, and clicking or locking of the joint. TMD is often multifactorial and can be managed with conservative treatments, though severe cases may require more advanced interventions.
