In the US you need an undergrad plus 4 years of dental school. Most dentists then start practice immediately, although some go on to do a residency in Orthodontics or other area. Oral surgeons do a 5 year residency after dental school, and are usually awarded an MD as well as the DDS from dental school. Physicians do undergrad + 4 year med school + 3-9 years of residency / fellowship.
