You will need to retake the DATs.
It's alright, lots of people retake. I did. In fact, after my retake I was almost instantly invited to another interview.
Looking at your scores, there is no doubt that you are able to do well in your sciences at dental school. The issue lies with your RC of 15. You're going to have to get that higher. As a dentist, effective communication, both written and verbal is paramount. I don't think too much weight is placed on QR, but it affects your AA.
Study, retake your DATs, make sure someone goes over your personal statement, and prepare for interviews. I'm sure there are lots of resources for effective communication. Then apply early!! Once you do that I'm sure you will score some interviews.
Good luck!!
