How is a Pediatric Dentist different from a general dentist? Pediatric dentists like other dental specialists (orthodontist, oral surgeons, endodontist, and other) complete dental school with their general dentist colleagues, but then continue on for additional training. Pediatric Dentists spend 2-3 years of focused training on the care of infants, children, and adolescents. This training includes extensive study of growth and development, care of patients with a variety of medical conditions, behavior management, and much more.
