Why does a three-year-old baby grind his teeth at night?

Babies love to grind their teeth, and parents are very worried. Some adults think that if it is an adult grinding their teeth, it is just a little unpleasant, and the people around can't sleep peacefully, but there is nothing else. But if it is a child grinding his teeth, it is different. Children grinding their teeth will affect their intelligence and physical development. Three-year-old babies always grind their teeth when they sleep, and parents are worried that their children will not grow tall. So what is going on with three-year-old babies grinding their teeth in the middle of the night?

There are many reasons why children grind their teeth, such as:

Intestinal parasites

The toxins produced by roundworms can stimulate the intestines, speed up intestinal peristalsis, cause indigestion, pain around the umbilicus, and disturbed sleep; if the toxins stimulate the nerves, causing nerve excitement, it can lead to teeth grinding. Pinworms also secrete toxins and cause anal itching, affecting children's sleep and causing teeth grinding sounds. Most parents believe that the culprit of teeth grinding is parasites, but in recent years, due to improved hygiene habits and conditions, teeth grinding caused by parasites has taken a back seat.

Excessive mental stress

Many children watch thrilling fighting scenes on TV at night or play too much before going to bed, which can also cause bruxism due to mental stress. If you are scolded by your parents for a long time because of something, it will cause depression, uneasiness and anxiety, which is also an important reason for nocturnal teeth grinding.

Digestive disorders

If children eat too much at night, a lot of food will accumulate in their intestines when they go to sleep. The gastrointestinal tract has to work overtime, and due to the heavy burden, it will cause involuntary teeth grinding while sleeping.

Nutritional imbalance: Some children have the habit of being picky about food, especially not liking to eat vegetables, resulting in nutritional imbalance, leading to deficiency of calcium, phosphorus, various vitamins and trace elements, causing involuntary contraction of the facial chewing muscles at night, and the teeth will grind back and forth.

Poor tooth growth and development

During the period of tooth replacement, if a child suffers from rickets, malnutrition, congenital missing teeth, etc., the teeth will be underdeveloped, and the occlusal surface will be uneven when the upper and lower teeth touch, which is also the cause of nocturnal bruxism.

In fact, there are many reasons why children like to grind their teeth. The reason why many adults grind their teeth is actually the same reason why children grind their teeth. Teeth grinding may be caused by too much psychological pressure and bad sleeping habits. Many adults often stay up late, which can also cause teeth grinding. For children, it is very likely that the teeth grinding is caused by external influences and interference.
