Bruxism "Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. Bruxism has two distinct circadian manifestations: it can occur during sleep (indicated as sleep bruxism) or during wakefulness (indicated as awake bruxism)."All forms of bruxism entail forceful contact between the biting surfaces of the upper and lower teeth.

Clenching (or clamping), on the other hand, involves inaudible, sustained, forceful tooth contact
