What is missing from child molars at night?

Children molars at night are mostly lack of vitamin D. If the child lacks vitamin D, it will cause trace element metabolism disorder in the body, causing bone decalcification, muscle soreness and vegetative nerve disorder, thus causing sleep molars at night. In addition to this reason, molars will also be caused by the following reasons: 1. The existence of parasites in the body will absorb nutrients from children, stimulate intestinal wall, cause indigestion, and thus cause molars at night. 2. Mental stress or excitement. If the child's nervous system is too excited before going to bed, it is also easy to grind teeth at night. 3. If the baby often sleeps on one side of the head, it will cause the masticatory muscles to be uncoordinated and thus cause molars. 4. Over-eating dinner increases the burden on the gastrointestinal tract and thus causes sleep molars.
