Question
My child is nine months old and has not grown any teeth yet. Is this a normal phenomenon? Additionally, the child’s hair is also rather sparse.
Answer
A nine-month-old baby not having grown any teeth falls within the category of delayed teething. Generally, babies may start growing teeth around the age of one. Since the baby is only nine months old, it can be observed continuously. Full-term babies should start supplementing with 400 units of vitamin D daily from 15 days after birth to promote calcium absorption. If supplementation is not timely, it may lead to calcium deficiency, which can in turn affect tooth growth.
