What Is TMJ Disorder?
You have two temporomandibular joints (TMJ) — they’re located just below your ears. They work like hinges, allowing your jaw to move in several directions.
TMJ Disorder (TMD) is a condition that affects one or both of your temporomandibular joints. The most frequent cause of TMD is bruxism, which is clenching and teeth grinding that often occurs at night while you sleep. Additional factors that contribute to TMD include arthritis, chewing hard objects such as ice, or an injury caused by a blow to the region.
If your jaw hurts while you’re talking or eating, you hear popping noises when you open or close your mouth, or you suffer from frequent migraines, you could be suffering from TMJ Disorder.
