What is the problem of children grinding their teeth when sleeping? What should I do?

Parents can't help but worry when their children grind their teeth while sleeping. At this time, you should first find out the reason. If it is because the child eats too much at dinner, the child can go to bed later. If it is caused by a bad sleeping position, parents can help the baby adjust the sleeping position.

1. Misaligned teeth, excessive use of the chewing muscles or long-term chewing on one side of the teeth, as well as poor tooth occlusion, temporomandibular joint dysfunction, can also cause nocturnal bruxism. Moreover, babies with uneven teeth often have abnormal positions of their chewing muscles. When they sleep at night, their chewing muscles often contract unconsciously, causing bruxism.

2. Eating too much for dinner or having a snack before going to bed will not only affect the absorption of nutrients, but also increase the burden on the gastrointestinal tract. Because when you fall asleep, there is still a lot of undigested food accumulated in the gastrointestinal tract, the entire digestive system has to "work overtime" and continue working. Even the chewing muscles are mobilized and involuntarily contract, causing teeth grinding.

3. Babies who lack vitamin D. Due to the disorder of calcium and phosphorus metabolism in the body, it will cause bone decalcification, muscle soreness and autonomic nervous system disorder, and often cause excessive sweating, night terrors, irritability and nocturnal teeth grinding.

4. Mental tension or excitement . Some babies do not usually grind their teeth, but if they listen to a gripping story before going to bed, or just finished watching scary or tense TV or cartoons, they may grind their teeth at night because their nervous system is overly excited. Another reason is stress. For example, the baby is not adapting to kindergarten life, is afraid of a certain child in the class, quarrels with parents or family members, etc. These will make the baby nervous and cause the baby to grind his teeth when sleeping at night. Additionally, some overactive babies may also grind their teeth at night.

5. There are parasites in the intestines . Ascaris parasitizes in the baby's small intestine, not only robbing nutrients, but also irritating the intestinal wall, secreting toxins and causing indigestion. If your baby's stomach often aches, it can cause insomnia, irritability and nighttime teeth grinding.

Pinworms can also cause teeth grinding. Pinworms usually parasitize in the human large intestine. After the baby falls asleep, the pinworms will quietly crawl to the anus to lay eggs, causing anal itching, making the baby sleep uneasily and causing teeth grinding.

6. Bad sleeping posture . If the baby's head often tilts to one side when sleeping, it will cause incoordination of the chewing muscles, causing abnormal contraction of the chewing muscles on the compressed side, resulting in bruxism. When babies sleep with their heads covered at night, excessive accumulation of carbon dioxide and insufficient oxygen supply can also cause teeth grinding.
