Millions Grind Teeth While Sleeping

Up to 31% of children and between 10% and 15% of adults grind or clench their teeth at night, a condition known as sleep bruxism. It is strongly linked to stress, anxiety, depression, and physical symptoms like morning headaches, jaw soreness, and temporomandibular joint (TMJ) pain. Night guards do not stop the grinding itself; instead, they serve to protect teeth from the long-term damage it causes.
