Do you ever wake up with a sore jaw? If so, it could be a sign that you’re grinding your teeth while you sleep. Chronic teeth grinding , also known as bruxism, can be caused by a number of things, including sleep disorders, anxiety, and temporomandibular joint (TMJ) disorders. Other signs of bruxism include persistent morning headaches, earaches, teeth that feel loose, and cracked teeth. If you notice any of these symptoms, contact your dentist in Renton, WA, right away for an appointment. To learn how bruxism is treated, watch this video from the American Dental Association.
