Relevant medical history, for instance, past bruxism-related problems and information on any medical conditions. People with sleep bruxism don’t grind their teeth throughout the night. Instead, they have episodes of clenching and grinding which usually last up to one second. People may have very few episodes per night or up to 100. The frequency of episodes is often inconsistent, and teeth grinding may not occur every night. AskMayoExpert. Bruxism. Rochester, Minn.: Mayo Foundation for Medical Education and Research; 2017.One exercise that has been shown to relax the muscles involved in teeth grinding follows these steps: Reduce stress. Listening to music, taking a warm bath or exercising can help you relax and may reduce your risk of developing bruxism. Amir I, Hermesh H, Gavish A.

Reports of SSRI-associated bruxism in the family physician office. J Orofac Pain. 2001. 15:340-346. Most people who brux are unaware of the problem, either because there are no symptoms, or because the symptoms are not understood to be associated with a clenching and grinding problem. The symptoms of sleep bruxism are usually most intense immediately after waking, and then slowly abate, and the symptoms of a grinding habit which occurs mainly while awake tend to worsen through the day, and may not be present on waking.

J Neuropsychiatry Clin Neurosci. 2004. 16(3):381-2. [QxMD MEDLINE Link]. Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; reports of prevalence range from 8% to 31% in the general population. [2] Several symptoms are commonly associated with bruxism, including aching jaw muscles, headaches, hypersensitive teeth, tooth wear, and damage to dental restorations (e.g. crowns and fillings). [3] Symptoms may be minimal, without patient awareness of the condition. If nothing is done, after a while many teeth start wearing down until the whole tooth is gone.
