The causes of horse teeth are germ keratin, pathological factors, and normal physiological factors. Newborn babies are toothless, and by rubbing the gums against each other, keratin is produced. If there is too much keratin, it is easy to form a fleshy lump of the same size as a grain of rice, and thus horse teeth appear. Whether eating formula or drinking breast milk, it is necessary to clean the baby’s mouth, otherwise a large number of bacteria can easily breed in the baby’s mouth and induce the differentiation of oral tissues causing cell accumulation, and this pathological factor can also lead to the appearance of horse teeth. Horsetooth will appear six months after the baby is born, when there will be a fleshy lump on the baby’s milk tooth germ, usually due to normal physiological factors that cause horsetooth. Under normal circumstances horse teeth will not affect the health of infants, so do not use sharp objects to pick horse teeth, otherwise it may induce oral diseases in infants, but if there is crying, not eating and other phenomena, you should promptly take the baby to the doctor.
