Have you noticed? When your child sleeps at night, he or she often makes a “gurgling” sound and grits his or her teeth, which is a symptom of teeth grinding. Many parents think that their children grind their teeth because they have worms in their stomachs, and will go to the drugstore to buy deworming medication to give their children worms, but the actual effect is very little. Because children grind their teeth, tummy worms are only one of the reasons, there are other reasons, such as the child is too excited, too full and so on. It is important to understand the real reasons why babies grind their teeth so that we can help our children to change the problem of teeth grinding. Reason 1: Too excited before bedtime? Some babies play outside to their heart’s content all day long, and before they go to bed at night, their minds keep thinking back to what happened during the day, which is brain excitement. Children who fall asleep in an excited state are prone to teething, and the main way to control the child’s entertainment program for these kinds of children is to let the child relax a little bit before going to bed, and listen to some calming light music, which can make the child fall asleep in a soothing state. Reason 2: Too full dinner? Overfilling dinner is also the main reason why your child will grind his teeth. As the child eats too much dinner, there is still a lot of undigested food in the stomach when the child goes to sleep, so the stomach and intestines will continue to work after the child goes to sleep to digest the food, and at this time, the chewing muscles will also work with the digestive system to participate in the work, which will lead to the child’s sleep grinding teeth. For children who grind their teeth for this reason, parents should be careful to avoid letting their children eat too much at dinner, and try not to eat again before going to bed, to eat a reasonable diet. Cause 3: Calcium deficiency? A child’s lack of calcium can make the child’s mood irritable, leading to the child’s restless sleep at night, thus grinding his or her teeth while sleeping. Some children are picky eaters and usually take less calcium, plus they like to stay at home and seldom participate in outdoor interactions, resulting in lower calcium levels in the body. To face this situation, on the one hand, parents should take their children to participate in more outdoor activities and sunshine to promote the absorption of calcium; on the other hand, they can take calcium tablets or cod liver oil and other external ways to increase the calcium content in the body. Cause 4: Intestinal parasites? Due to the incomplete development of the gastrointestinal tract, there are some parasites in the intestines, such as common roundworms, which plunder nutritious food, stimulate the intestinal wall, and secrete poisonous substances in the intestines, which lead to teeth grinding in the child’s sleep. In the face of this situation, parents can go to the pharmacy to buy some anthelmintic drugs, pay attention to the usual dietary hygiene, to help children develop good dietary hygiene habits. Reason 5: bad sleeping position? Poor sleeping posture can also lead to teeth grinding, because the child sleeps sideways for a long time, which will cause the chewing muscles to be uncoordinated, thus leading to teeth grinding. In addition, children sleeping with their heads covered can also lead to teeth grinding in their sleep. Parents should pay more attention to their children’s sleeping posture, and help them to correct it once they find that their children’s sleeping posture is uncoordinated. Especially in winter, don’t let your child sleep with his head covered.
