busupshot83, consider that there are more spots for D1 than for the advanced 2 years program.
A friend of mine after doing all the research and after having gone to dental school abroad, decided to apply for dental school again in the US. Reason: money and chances of getting a spot. It's easier for her to go to dental school all over again, than to go to an advanced program. at least in her view, I don't neccesarily agree. Of course schools will take her previous dental degree as her undergraduate studies, because she didn't major in anything previously.
