Pediatric dentists have an additional two to three years of training at university pediatric facilities in addition to four year of dental school and four years of college study. Some pediatric dentists, like Dr. Kim, practice general dentistry before specializing, giving them a unique perspective.

Also, they are trained and qualified to treat special needs patients.
