> Most dentists spend three years in school

Where can you get a dentistry degree with just three years of university? I thought in the US you needed an undergraduate degree of four years just to get into the postgraduate dentistry degree, so at least seven years in total, which seems like a long time to me! In the UK it's at least five years.

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.
