Question
Is it normal for a baby to start teething at four months old?
Answer
Babies typically begin to grow primary teeth between 4 and 10 months after birth. If no teeth have emerged by 12 months, it is considered a delay in primary tooth eruption. The order of tooth eruption usually follows from the bottom up, from front to back, and the teeth are generally all in place by around 2 and a half years old. The timing and order can vary due to factors such as genetics, endocrine function, and the nature of food.
