Bruxism is the conscious or unconscious act of clenching your teeth together. This destructive habit can prematurely wear the enamel from the tops of our teeth. Often, people who brux report that the muscles on the sides of their face will be painful, or locked in spasm.
People who brux can wear the cusps away from their back teeth, leaving hollowed shells of what were once tall, strong teeth. As this process continues, and the back teeth are worn down, the forces are transferred to the more delicate front teeth. We may one day notice that our front teeth have become very flat, this is the result of bruxism.
