Disturbance of the dopaminergic system in the central nervous system has also been suggested to be involved in the etiology of bruxism. Evidence for this comes from observations of the modifying effect of medications which alter dopamine release on bruxing activity, such as levodopa, amphetamines or nicotine.

Many studies have reported significant psychosocial risk factors for bruxism, particularly a stressful lifestyle, and this evidence
