What is the difference between a DDS and a DMD? Also do you have to complete a 4 year undergrad program to get into dental school or can you do a 2 year? Also after you complete dental school if you want to stick with the education you have and go no further what exactly do you become, just a plain ole dentist, like the one you go visit at the dentist office? Also I know there are different specialities in dentistry like becoming an orthodontist and endodontist and so on, but how do you get into those field, like do you have to do a residency type program after dental school?
