Children’s milk teeth yellow spot is divided into two kinds of cases, one is the tooth itself does not have yellow spot after eruption due to feeding or oral hygiene problems and make the tooth surface demineralization, pigmentation formation, this kind of yellow spot for shallow caries, need to carry out remineralization treatment. A kind of yellow spots on the surface of milk teeth at birth, basically do not need to carry out any treatment, this is mainly because the mothers may be exposed to radiation during pregnancy or take drugs, resulting in the formation of yellow spots in the fetal period of the tooth embryo is not fully grown. If the yellow spots affect the appearance of the baby teeth, filling can be considered, but in most cases it is very difficult to fill these spots by bonding. Of course, yellow spots on milk teeth do not mean that permanent teeth will still grow yellow spots, because the development time is different, permanent teeth usually start to develop after the child is born, and the relationship with the mother is not too big, so parents do not need to worry too much about the yellow spots on milk teeth will affect the child.
