There is an essential difference between horse teeth and milk teeth. Horse teeth are epithelial beads, which are not real teeth, but just an accumulation of epithelial cells, while milk teeth are normal teeth. Horse teeth are epithelial beads, which are yellowish-white dots formed by the accumulation of a large number of epithelial cells, and are not real teeth. Most of them appear 4~6 weeks after birth, and gradually fall off with the increase of age in months, and do not affect the normal health. Milk teeth are the first set of teeth erupted by children, most of them start to erupt around 6 months, and come out around 2~3 years old, and at the stage of 6~12 years old, the milk teeth are replaced one by one by the permanent teeth in the same position, so the milk teeth are the real teeth. Horse teeth and milk teeth are different substances of gum growth, appearing at different times and of different natures. Whether it is during the growth of horse teeth or the eruption of milk teeth, it is important to pay attention to good oral hygiene.
