One or more pediatric dentists are available in Portland. A pediatric dentist is one who is specialized in the dental care of children, from birth through adolescence. This requires special emphasis on common childhood teeth problems, along with a thorough understanding of child psychology to make a dentist appointment an interesting, enjoyable affair. The pediatric dentist also tries to inculcate in the children the need for comprehensive dental care. The American Board of Pediatric Dentistry, Diplomate ABPD, certifies a pediatric dentist after two or three years of further studies after obtaining the dentistry degree.
