Careful mothers will always notice many abnormalities in their babies, such as not liking to eat, being picky eaters, or not sleeping soundly at night, gritting their teeth, and so on. Perhaps in daily life, we can find that many adults also have the phenomenon of gritting their teeth at night. So what is the reason for a two-year-old baby gritting their teeth while sleeping?
1. It may be the presence of roundworms or intestinal parasites in the baby's stomach. The roundworms or parasites in the baby's belly can plunder some nutrients from the baby's belly, stimulate the baby's intestinal wall, and cause indigestion, which can to some extent cause the baby to grit their teeth at night.
2. It may be that the baby ate too much for dinner. If a baby eats too much before bedtime and does not digest it, it will increase the burden on the digestive system during sleep, forcing the digestive system to work overtime and even the chewing muscles to involuntarily contract, causing the baby to grit their teeth.
3. The baby is too excited to play during the day. If a baby plays with excitement or fatigue before going to bed, or is frightened, it can cause the imbalance of excitation inhibition in the cerebral cortex, triggering the contraction of the baby's facial chewing muscles and resulting in nighttime gritting.
4. The baby's nutrition is unbalanced. If a baby has picky eating behavior, it may lead to a deficiency of trace elements such as calcium, phosphorus, or some vitamins, which can also cause contraction of the chewing muscles at night and result in grinding teeth.
