Alabama, Mississippi and South Carolina require you to have lived in the area for 1 year prior to admission or enrollment (varies). Also, moving there to take classes isn't what they like to see. Their admission stats are higher than most other schools though.
TN requires you to live there for a year or to pay taxes in TN basically.
Transferring to a school in those areas would work pretty well if you change everything over I guess. You'd pay out of state for the time you're in undergrad and they might take you as an in state student for dental school.
But don't move to MS, it's a pretty hard school to get into.
