Sleep bruxism<\/strong> is an involuntary habit of clenching or grinding teeth during sleep<\/strong>. It\u2019s a common sleep-related movement disorder that affects both adults and children.<\/p>\n
According to the American Academy of Sleep Medicine (AASM)<\/strong>, about 8\u201310% of adults<\/strong> and up to 15% of children<\/strong> experience sleep bruxism. While occasional teeth grinding may not cause harm, chronic bruxism<\/strong> can lead to:<\/p>\n
\n
Worn-down tooth enamel<\/li>\n
Jaw discomfort or temporomandibular joint (TMJ) pain<\/li>\n
Morning headaches<\/li>\n
Disrupted sleep for both the individual and bed partner<\/li>\n<\/ul>\n
Many people don\u2019t even realize they grind their teeth until a dentist notices signs of wear \u2014 or a partner mentions hearing grinding sounds at night.<\/p>\n

\ud83e\udde0 The Science Behind Bruxism<\/h3>\n
Sleep bruxism is classified as a sleep-related movement disorder<\/strong>, often associated with arousal episodes<\/strong> during light sleep stages.<\/p>\n
In other words, the brain partially \u201cwakes up,\u201d triggering brief muscle activity \u2014 including jaw clenching.<\/p>\n
While the exact cause isn\u2019t fully understood, research points to a combination of neurological, psychological, and physiological<\/strong> factors.<\/p>\n\n
