Infants generally begin to erupt their milk teeth 6 to 8 months after birth. In general, the middle incisor erupts at 6 to 8 months after birth, then the lateral incisor, first molar, cuspid and second molar erupt sequentially, and all the milk teeth erupt at about 2 and a half years old. The time and order of eruption of milk teeth have obvious individual differences, related to genetics, endocrine and so on, and the health of teeth is related to protein, trace elements, vitamins and other nutrients. During the period of eruption, pay attention to good oral hygiene for infants, and you can use teething sticks appropriately to assist the growth of baby’s teeth. If there is a delay in the eruption of baby teeth, it is recommended to go to the stomatology department of the hospital to find out the cause in detail before treatment.
