Welcome to the forums.
You have a better chance getting into another medical school than getting into dental school (see the new schools that have opened on the MD and DO front), and that is even a little challenging. The two are not the same, and dental curricula are not easier than medical curricula. You like hands-on work? Maybe you've seen the movie Whiplash?
Okay, maybe it won't be like that with your dental preceptor. Not exactly.
