An abnormal aversion of grinding the teeth together because of the damage or pain which excessive teeth grinding or jaw clenching might cause: Bruxophobia occurs when someone is afraid that he or she could have oral health complications brought on by dentition grating, therefore causing impairment, injury, or other oral health complications.
