What is bruxism?
Bruxism refers to clenching and grinding your teeth. Nocturnal (nighttime) bruxism is more common and occurs while you sleep, but you can also suffer from it during the day, especially when concentrating or under stress.
Prolonged bruxism can damage your teeth and your jaw joints, as well as cause headaches. It can also lead to TMJ dysfunction, a chronic jaw condition that affects millions of Americans.
