N: 1. “grinding the teeth unconsciously,” from Greek ebryxa, aorist root of brykein “to gnash the teeth.”
2. The habit of unconsciously gritting or grinding the teeth esp. in situations of stress or during sleep.
3. Bruxism is commonly considered a detrimental motor activity, potentially causing overload of the stomatognathic structures. The etiology of bruxism is unclear, but the condition has been associated with stress, occlusal disorders, allergies and sleep positioning. Due to its nonspecific pathology, bruxism may be difficult to diagnose. Unfortunately, very little data exists on the subject of a cause-and-effect relationship of bruxism to the point that expert opinions and cautionary approaches are still considered the best available sources for suggesting good practice indicators.
4. Colloquialism: teeth-gnashing, teeth-grinding.
