What causes teeth grinding in children during sleep?

Bruxism in children, medically referred to as nocturnal tooth grinding or bruxism, may be caused by various factors. In children, bruxism might be related to growth and development, and could naturally occur during the adjustment of tooth alignment. Stress, anxiety, or poor sleep quality also can trigger bruxism. Certain medical conditions, such as parasitic infections, malocclusion, or neuromuscular disorders, may also be associated with it.

Overeating or consuming hard-to-digest food during dinner can burden a child's gastrointestinal system, causing the digestive system to continue working during sleep, which might trigger contractions of the facial chewing muscles and lead to bruxism. In younger children, the nervous system may not be fully developed, which also could contribute to nighttime bruxism. As the child grows and develops, this condition typically improves gradually.

Parents can create a relaxing pre-sleep environment for their child to reduce tension and anxiety. Regular dental checkups should be conducted to maintain oral health. Monitor the frequency and symptoms of the child's bruxism, and if there is persistent discomfort or significant tooth wear, seek medical attention promptly.
