Introduction
In general, teeth grinding in children may be caused by factors such as intestinal parasitic infections or overeating. Roundworms (Ascaris lumbricoides) parasitize the infant’s small intestine, not only depriving the host of nutrients but also irritating the intestinal wall and secreting toxins, leading to indigestion. Infants often experience vague abdominal pain, which can result in insomnia, irritability, and nocturnal bruxism (teeth grinding). Additionally, pinworms (Enterobius vermicularis) may also contribute to molar grinding.
In daily life, many people talk in their sleep, snore, or grind their teeth—behaviors that not only disturb others’ sleep but also harm their own health. A common myth about teeth grinding is that it indicates a family’s financial prosperity during leisure time; this belief is absolutely false. So, what causes children to grind their teeth?
Causes of Teeth Grinding in Children
Teeth grinding in children is commonly associated with factors such as intestinal parasitic infections and overeating. For instance, roundworms (Ascaris lumbricoides) inhabit the infant’s small intestine, where they not only deprive the host of essential nutrients but also irritate the intestinal wall and secrete toxins, leading to indigestion. Infants often experience vague abdominal pain, which may result in insomnia, irritability, and nocturnal bruxism (teeth grinding). Additionally, pinworms (Enterobius vermicularis) can also cause teeth grinding. Pinworms typically reside in the large intestine, impairing nutrient absorption and increasing gastrointestinal burden. When substantial undigested food remains in the gastrointestinal tract at bedtime, the entire digestive system must “work overtime,” continuing its activity throughout the night—even triggering involuntary contractions of the masticatory muscles, resulting in teeth grinding.
Disruptions in calcium and phosphorus metabolism can lead to bone demineralization, muscle aches, and autonomic nervous system dysfunction, frequently manifesting as excessive sweating, night terrors, restlessness, and nocturnal bruxism. Some children who normally do not grind their teeth may begin doing so after hearing an exciting story before bed—or immediately following exposure to frightening or highly stimulating television programs or cartoons—due to excessive nervous system arousal.
It is recommended to consume more vegetables and fruits rich in vitamin C and other essential nutrients, eat light yet flavorful meals, and prioritize adequate rest. We hope this information proves helpful to you.
