Why do children grind their teeth at night?

Children may have many abnormal reactions when sleeping at night, and teeth grinding is a relatively normal one. Many parents must have noticed this problem at ordinary times, but they don’t know the specific cause, so they will put it aside for the time being. Today, the editor mainly wants to explain the reasons for teeth grinding. If you need to know, please read the following article together.

1. Intestinal parasites. Your baby has parasites in his intestines, such as roundworms and pinworms. Ascaris parasitizes in the small intestine of children, robbing them of nutritious food, irritating the intestinal wall, and secreting toxic substances. This causes dull stomach pain in children, affects their sleep, and causes them to grind their teeth while sleeping. In addition, pinworms parasitize in the large intestine of children. After the child falls asleep, the pinworms will quietly crawl to the anus to lay eggs, causing anal itching, making the child sleep uneasily and causing teeth grinding.

2. Bad sleeping posture. If a child sleeps on one side for a long time, it will cause incoordination of the chewing muscles. The chewing muscles on the pressured side will continue to contract abnormally, resulting in bruxism. In addition, it is not good for children to sleep with their heads covered, as this will lead to increased carbon dioxide concentration and lack of oxygen, causing children to grind their teeth while sleeping. Parents should pay more attention to their children's sleeping posture. If they find that their children's sleeping posture is not good, they should correct it in time.

3. The teeth are not aligned properly. If a child's chewing muscles are overexerted or biased to one side, and if the teeth have a bad occlusion, temporomandibular joint dysfunction may occur, which may also cause nocturnal bruxism. If a child's teeth are not aligned properly, the position of his or her masticatory muscles will often be abnormal. When a child sleeps, the masticatory muscles will contract abnormally, leading to teeth grinding at night.

After reading this article, I believe that parents have more or less understood some of the factors that may induce children to grind their teeth. Therefore, they must pay attention to it and promptly find out the specific causes. They can also go to the pediatric clinic for a detailed examination and make corresponding corrective treatments to eliminate this adverse symptom as soon as possible.
