Your child’s primary or baby teeth are just as important as his or her permanent ones. Healthy and strong baby teeth are vital in helping your child chew food and for speech development. A newborn usually has around 20 primary teeth developing inside the gums. Around 6 months old, the child’s first teeth begin to show up. These are usually the front two upper or lower teeth. By the age of 3, all his or her primary 20 teeth usually have erupted.
