The quick answer is yes, that is enough for dental school. But there is a lot more that goes into it. If you get a 16 on your dat then no, your 3.25 gpa isn't very good. If you get a 24 though, then yes, your gpa is 100% fine. With that GPA I would shoot for at least a 19 on the DAT to be competitive though. Also, EC's have a lot to do with it.
