Your GPA will raise flags with your DAT scores. There are plenty of applicants that have taken hard classes/majors that do quite well and that is who you will be going up against when you apply. I agree with DATtestTho, there is no "try to get A's", you have to get A's to show you can handle the coursework in Dental school. Your EC's are ok, but they are all dental focused. Not that having some dental focused EC's are bad, but they do want more well rounded candidates at most dental schools, but it is what it is now. What you need to figure out is why you have such a low GPA and fix that.
