I'm applying to dental school now and I know this residency is a long time away, but I have this one concern. Is it easier/necessary to go to dental school in the same state as where you do residency/where you want to live? Is it easy to move? Do you have to retake any exams or get new licenses when you move to a new state? Finally, in terms of residency admissions, do they mostly take dental students who are in their own state?
