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 clench or grind them at night (sleep bruxism).
Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnea).
Mild bruxism may not require treatment. However, in some people, bruxism 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.
