I took all of my pre-reqs at my community college before I transferred, and in my 4 dental school interviews, at 3 it didn't come up at all (Columbia, Howard, Pittsburgh), and at 1 (Loma Linda), my interviewer mentioned that they somewhat look down on taking too many pre-reqs at the CC. So, I'd suggest probably not taking all Ochem, Gchem, and Physics like I did before you transfer, maybe just 2 out of the 3 - but if you find that it will be much more convenient for you to take all 3 at the CC, then sure, go for it, but know that there will be a slight stigma.
In the long run, going to a CC will affect you slightly to none as far as your chances for dental school. What WILL affect you is if you do awesome at the CC and then start doing really badly once you transfer, they'll look badly at that. So, as long as you can prove to them that you can hold your own in higher division classes you're fine.
I got into 3 dental schools from the CC (Just interviewed at Loma Linda last week, so I'm still waiting on that), so you can too, just keep up the hard work.
