Let's start by asking ourselves some specific questions: Is bruxism an oral parafunctional activity,<ref name="Wassell 20082">Wassell R, Naru A, Steele J, Nohl F (2008). ''Applied occlusion''. London: Quintessence. pp. 26–30. ISBN <bdi>9781850970989</bdi>.</ref> that is, is it not physiologically related to normal function such as eating or speaking? Is bruxism a common behavior despite reports of prevalence ranging from 8% to 31% in the general population?<ref>Manfredini D, Winocur E, Guarda-Nardini L, Paesani D, Lobbezoo F (2013).

If no action is taken, after a while many teeth begin to wear out until they disappear completely, the question that arises is: do teeth wear out equally in the life cycle even without grinding?<blockquote>A theory called 'Thegosis' studied by a group of New Zealand researchers<ref>Every, RG. The significance of extreme mandibular movements. Lancet 1960; (2):37-39</ref><ref>Every, RG. The teeth as weapons. Lancet 1965; (1):685-688</ref>has always maintained that bruxism is a physiological function that increases masticatory capacity and organic muscle strength, therefore, where is the boundary between physiology and pathology?</blockquote>

They seem irrelevant questions but let's see what can be deduced from the literature. There are, of course, multiple factors<ref>Cawson RA, Odell EW, Porter S (2002).
