When children grind their teeth at night, parents are very concerned about whether this is a medical condition. The following is a comprehensive analysis for you. 1, intestinal parasites in the stomach roundworms. Ascaris parasites in the child’s small intestine, not only plunder nutrients, but also stimulate the intestinal wall, secrete toxins, causing indigestion. The frequent vague pain in the child’s stomach can cause insomnia, irritability and nighttime teeth grinding. In addition, pinworms can also cause teeth grinding. Pinworms are normally parasitic in the human colon, and after the child goes to sleep, the pinworms will quietly crawl to the anal opening to lay eggs, causing anal itching, making the child sleep restlessly and grinding teeth. Response strategy: Deworm your child. Usually develop good hygiene habits. 2, over-eating dinner dinner over-eating, or extra meals before bedtime, not only affect nutrient absorption, but also increase the burden on the gastrointestinal tract. Because of sleep, the gastrointestinal tract is still a lot of undigested food, the entire digestive system will have to “overtime”, continuous work, even the chewing muscles are mobilized, involuntary contraction, causing teeth grinding. Coping strategies: do not let the child eat too much before bedtime, after eating a little stay a while and then let the child go to bed. 3, lack of vitamin D rickets children, due to the body of calcium, phosphorus metabolism disorders, will cause bone decalcification, muscle pain and plant nerve disorders, often sweating, night terrors, restlessness and grinding teeth at night. Coping strategy: under the guidance of the doctor to the child to supplement vitamin D, calcium tablets, usually more sunshine, night grinding situation will gradually reduce. 4, mental factors there are a few children usually do not grind teeth, but if you listen to a heart-stopping story before going to bed, or just after watching horror, nervous TV or cartoons, due to the nervous system is too excited, there will also be night grinding. Another reason is stress, such as not adapting to kindergarten life, fearing a certain child in the class, arguing with parents or family members, etc., can make the child’s mind tense and lead to grinding teeth at night. In addition, some overly active children can also occur to grind their teeth at night. Coping strategies: Don’t let your child watch TV that is too stimulating before bedtime. Often communicate with teachers and children, if the child has a knot, help him solve it in time to relieve his psychological pressure. 5, the teeth are not aligned chewing muscle force too much or long-term chewing with one side of the teeth, as well as the teeth bite relationship is not good, the occurrence of temporomandibular joint dysfunction, will also cause night grinding teeth. Moreover, children with unevenly aligned teeth, the position of his chewing muscles is often abnormal, and at night during sleep, the chewing muscles often contract unconsciously, causing teeth grinding. Coping strategy: Take your child to the dentist regularly, and do orthodontics and treatment according to the doctor’s recommendations. 6, bad sleep posture if the child sleeps with the head often to one side, it will cause the chewing muscles to be uncoordinated, so that the side of the chewing muscles under pressure to occur abnormal contraction, and thus the appearance of teeth grinding. Children sleep with their heads covered at night, due to the excessive accumulation of carbon dioxide and insufficient oxygen supply, will also cause teeth grinding. Coping strategies: If you find your child sleeping in a bad position, help him to adjust it in time. Usually do not let children develop the habit of sleeping with their heads covered.
