What causes teeth grinding in children during sleep?

Possible causes of teeth grinding during sleep in children may include the following: 1) Misaligned tooth growth may prevent the mouth from closing properly, leading to teeth grinding. 2) High levels of stress or emotional tension from studies or daily life may contribute to teeth grinding. 3) Insufficient calcium levels in the body may also trigger teeth grinding. 4) Eating too much at night, which burdens the gastrointestinal system, may induce teeth grinding. 5) Ascariasis (intestinal worm infection) may also cause teeth grinding symptoms.
