Did you know that a pediatric dentist completes an additional two to three years of medical school than an ordinary dentist does?  The dental anatomy of a young child is very different compared to that of an adult.  A pediatric dentist also has valuable experience on the behavioral needs of kids that are restless and afraid.  A Pediatric dentist usually deals with cavities and the need for braces and some crowns while an adult dentists works a lot with crowns, root canals, and dental implants and other adult mouth problems.
