For example, enamel forms on the first permanent molars between birth and 2.5 years of age. The teeth affected can give us some clues.

Well, the team at Bitesize Pediatric Dentistry in Brooklyn is here to put your mind at ease by taking an in-depth look at what hypoplastic teeth are and how we can help manage this type of enamel defect.
