Patient's question:
Why is it that my baby is almost a week old and still hasn't grown any teeth? Is it because they are missing some trace elements? How should I supplement them?Patient Age: One week
Doctor's answer:
Hello, the embryonic form of deciduous teeth is called the dental germ, which develops during the fetal period. By the time the infant is born, the upper and lower jawbones already contain 20 dental germs of deciduous teeth. At this stage, these dental germs only have the crown and do not have the root; the root gradually develops after the infant is born. Around six months of age, the infant begins to grow deciduous teeth, starting with the lower front teeth, followed by the upper front teeth. By about two and a half years old, all 20 deciduous teeth have fully erupted. Therefore, since your baby is only one week old now, you don't need to worry. Wishing your baby good health.
