Will taking all the science prereqs at a CC hurt my chances of getting into dental school?

So I just graduated from a 4-year university with a 3.75 GPA and a B.S. in psychology. I have recently found an interest in dentistry and was looking to take all the science prerequisite classes at a community college. That being said, will taking those classes at a community college be frowned upon by dental schools? Also, if I apply to dental schools before I finish my prerequisites (but have them completed before dental school starts) would that also be something that is negatively viewed?
