Patient's question:
15 daysMy baby's teeth came out when they were 4 months old, and now they already have 8 teeth. Yesterday, I noticed a problem: it seems like his teeth aren't growing properly and are a bit short. Is it possible that he has poor dental development? Can anyone help me with this?
Doctor's answer:
When a child is born, there are no teeth in their mouth. At about 6 months after birth, the central incisors of the lower jaw begin to erupt, and by the age of 2 and a half, all deciduous teeth have fully erupted. Within the first year of a baby's life (1.5 months to 11 months), the mineralization of all deciduous teeth is completed, and within the first two years of life (6 months to 24 months), all deciduous teeth have erupted. Therefore, if a child develops systemic or localized disorders within the first year of life, it will affect the development of deciduous tooth enamel, leading to dental developmental defects and an increased risk of caries.There is a significant individual variation in the timing of tooth eruption. This is very important because the presence of individual variation means that some children's teeth erupt earlier, while others erupt later. However, as long as it falls within the range of individual variation, it is considered normal.
