Bruxism, characterized by the grinding and clenching of teeth, is often associated with psychiatric disorders such as anxiety and stress. Bruxism not only results in significant dental pathology but can also contribute to underlying neurophysiological disturbances.

To elucidate the relationship between bruxism and psychiatric medication by focusing on the neurophysiological mechanisms involved and the resultant dental pathologies.

A comprehensive literature review was conducted using databases such as PubMed, PsycINFO, and Google Scholar, focusing on studies from the last decade that investigate the association between bruxism, psychiatric medications, and neurophysiological factors. The review included clinical studies, neuroimaging research, and behavioral analyses.

The findings indicate a strong association between bruxism and the use of psychiatric medications, particularly antidepressants and antipsychotics. Neurophysiological studies reveal dysregulation in neurotransmitter systems, notably dopamine and serotonin, which play critical roles in both bruxism and the effects of psychiatric medications. This dysregulation affects motor control circuits and stress response pathways in the central nervous system, leading to involuntary teeth grinding and clenching.

Bruxism is both a symptom and a potential side effect of various psychiatric medications, rooted in neurophysiological disturbances. The interplay between dysregulated neurotransmitter systems, psychiatric medications, and resultant dental pathologies highlights the need for integrated dental and psychiatric care. Effective management of bruxism through targeted dental interventions and tailored psychiatric treatments can significantly improve both dental health and psychiatric well-being.
