The temporomandibular joint connects your jaw to the base of your skull. When this joint is injured or damaged, it can cause temporomandibular joint (TMJ) syndrome or temporomandibular disorder, which is a localised pain disorder (TMD). Injury to the teeth or jaw, misalignment of the teeth or jaw, teeth grinding or clenching, stress, poor posture, arthritis, and gum chewing are all causes of TMJ disorders. TMDs are a diverse set of musculoskeletal and neuromuscular disorders affecting the temporomandibular joint complex, as well as adjacent muscles and osseous components. TMD affects up to 15% of individuals, with a peak incidence between the ages of 20 and 40. The majority of diagnoses are made based on the patient's medical history and physical examination. When malocclusion or intra-articular abnormalities are suspected, diagnostic imaging may be helpful.
