Can't tell you much without a DAT score unfortunately. Also, average won't leave you being very competitive, and it's harder than it seems to get an above average score. Your GPAs are on the lower side, and you don't really have an "upward trend" so to say....I'd try to take more classes to bump them up, and make sure they're not easy As - take upper divs to show you can handle dental school. It's definitely not easy.
Focus on doing well on the DAT, creating a smart/strategic school list, and bumping your GPAs up a little and you should be good.
