Do you know when your child’s dental care should begin? The American Academy of Pediatric Dentistry recommends that the appearance of the first baby tooth is a good indicator For most babies, this occurs when they are between six months and one year of age. A simpler way to remember: first dental visit by first birthday. It’s important to remember that baby teeth serve as place-holders for adult teeth. If baby teeth are damaged, permanent teeth can grow in out of position, resulting in crowding and/or crooked teeth.
