My gpa is almost identical to that, and I got to nyu and temple in with a lat application. If I were you I'd focus on bringing the gpa up above 3.4 and doing as well as possible on the DAT's (I did Kaplan and that made all the difference, though many on this forum recommend topscore and achiever). You have two years to show the admissions committees that you can handle a tough science curriculum, so remember that when you take all your BCP (biology/chemistry/physics) exams, and you'll do fine. Also, start doing dental shadowing as soon as possible, it makes the interviews soooooo much smoother.
my two cents anyway,
