Bruxism (BRUK-siz-um) is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth together during the day or grind them at night, which is called sleep bruxism.

Bruxism may be mild and may not even require treatment. However, it can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems. Because you may have sleep bruxism and be unaware of it until complications develop, it's important to know the signs and symptoms of bruxism and to seek regular dental care.
