Patient's question:
A 4-year-old girl grinds her teeth at night and doesn't like to eat.Doctor's answer:
Common causes of children grinding their teeth at night include:1. Digestive dysfunction, such as: poor digestion, overeating at dinner, or excessive eating before bed can all lead to nighttime grinding. Additionally, intestinal parasites, especially roundworm infections, can also cause nighttime grinding, but grinding alone should not be used to diagnose intestinal parasites.
2. If a child is overly excited during the day, or if they have excessive academic pressure or watch stressful or stimulating movies before bed, their cerebral cortex may remain in an excited state, which can lead to grinding.
