I suggest you to apply for the next cycle instead of this one. If you submit your AADSAS application now, it will probably be end of February before AADSAS is done processing it. They then send it to the dental schools, which will look over the application. If you are fortunate enough to get any sort of interview, it won't be until end of March to April. By then, a good chunk of the class would have already been filled up, leaving you very little chance in getting in. Considering your stats are not particularly impressive, I really doubt your chances. I would, as others have suggested, try to take more classes to bump up your GPA. If you feel you could have done better on the DAT, try taking it again. Make sure you apply when the next cycle starts so you will get sort of an early advantage.
as far as the comment that "it won't hurt you", well, it definitely will. The application process is pretty expensive (a few hundred bucks) and I agree that if your stats don't improve all that much, being a second time applicant actually gives you more disadvantages than advantages.
