{{blockquote|"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)."<ref>{{cite journal|last1=Lobbezzo|first1=F.|title=Bruxism defined and graded: an international consensus|doi=10.1111/joor.12011|pmid=23121262|volume=40|issue=1|journal=Journal of Oral Rehabilitation|pages=2–4|year=2013|doi-access=free}}</ref>}}{{blockquote|All forms of bruxism entail forceful contact between the biting surfaces of the upper and lower teeth. In grinding and tapping this contact involves movement of the mandible and unpleasant sounds which can often awaken sleeping partners and even people asleep in adjacent rooms. Clenching (or clamping), on the other hand, involves inaudible, sustained, forceful tooth contact unaccompanied by mandibular movements.<ref name=":0">{{Cite journal|last=Nissani|first=M.|date=2000|title=A Taste-Based Approach to the Prevention of Bruxism|journal=Applied Psychophysiology and Biofeedback|volume=25| issue =  1 |pages=43–54|doi=10.1023/A:1009585422533|pmid=10832509|s2cid=32738976}}</ref>}}{{blockquote|"A movement disorder of the [[mastication|masticatory system]] characterized by teeth-grinding and clenching during sleep as well as wakefulness."<ref name="Wassell 2008" />}}
