If you have a child who has fears or behavioral problems, a visit to a regular dentist can be nightmarish for you, your child and everyone at the dentist's office. This is when a pediatric dentist is needed. Pediatric dentistry, also known as pedodontics, is the branch of dentistry dealing specifically with child oral care. This specialist receives additional training in child psychology, growth and development along with his or her regular dental training—providing them with the ability to work well with children.
