===Psychosocial factors===
Many studies have reported significant psychosocial risk factors for bruxism, particularly a stressful lifestyle, and this evidence is growing, but still not conclusive.<ref name="Shetty 2010" /><ref name="LOBBEZOO 2006" /><ref name="Manfredini 2009" /> Some consider emotional stress and anxiety to be the main triggering factors.<ref name="Poveda Roda 2007">{{cite journal |vauthors=Poveda Roda R, Bagan JV, Díaz Fernández JM, Hernández Bazán S, Jiménez Soriano Y |title=Review of temporomandibular joint pathology.

Awake bruxism often occurs during periods of concentration such as while working at a computer, driving or reading. Animal studies have also suggested a link between bruxism and psychosocial factors. Rosales et al. electrically shocked [[lab rat]]s, and then observed high levels of bruxism-like muscular activity in rats that were allowed to watch this treatment compared to rats that did not see it. They proposed that the rats who witnessed the electrical shocking of other rats were under emotional stress which may have caused the bruxism-like behavior.<ref name="LOBBEZOO 2006" />
