Is It Normal for a Girl to Grind Her Teeth at Night?

Question

Is it normal for a 4-year-old girl to grind her teeth at night and not want to eat?

Answer

Common causes of teeth grinding at night in children include digestive disorders, such as indigestion, overeating at dinner, or eating too much before bedtime. Additionally, intestinal parasitic infections, particularly roundworm infections, can also trigger grinding. However, it is not appropriate to diagnose a parasitic infection solely based on grinding teeth. Moreover, if a child is overly excited during the day, under heavy academic pressure, or watches tense and stimulating videos before bedtime, this may lead to an excited state of the cerebral cortex, thereby causing teeth grinding.
