Plural of bruxism; multiple instances of involuntary teeth grinding, usually occurring during sleep.
From Greek brychein (to gnash or grind) + -ism (suffix denoting a condition). Modern medical term that replaced older 'brutism.'
Bruxism affects millions—your dentist can tell if you brux because of the distinctive wear patterns on your teeth, and stress is a major trigger, which is why many people grind their teeth at night.
