#asktheexpert when does the first tooth erupt ? my baby is 9 months till now he has not erupted any tooth.

A. For most children, baby teeth erupt between 6 and 12 months. A slight delay is fine, but it may be time to see your dentist if your child has no teeth at 18 months. Delayed tooth eruption usually isn't a major cause for concern, but it never hurts to check.
