Some babies at a relatively young age will have slightly convex milky or yellowish-white particles at the edge of the gums, much like the teeth that grow out, commonly known as “horse teeth” or “plate teeth”, medically called epithelial beads. The horse teeth is a common physiological manifestation, not a disease, and does not affect the baby’s milk and the development of milk teeth, often in the weeks after birth gradually fall off naturally, so three months baby teeth generally do not need special treatment. However, if the baby’s teeth cannot fall off or are too big, accompanied by itching and swelling, which affects the baby’s feeding, parents need to pay attention to this time, do not deal with it at home, and should take the baby to the hospital for treatment in time. In daily life, the mother should pay attention to cleaning the nipples of breastfed babies during the period of long horse teeth, and for formula-fed babies, the mother should pay attention to the sterilization of bottles and teats. Do not pick or wipe the horse’s teeth, because after picking the horse’s teeth, it will cause local pain, affect the baby’s milk sucking, and bacteria are easy to invade from the damaged mucosa, and infection occurs. In mild cases, local bleeding or stomatitis may occur, and in severe cases, sepsis may be caused, endangering the baby’s health.
