I'd say these two schools are probably pretty equal in their undergraduate rankings and offerings. VCU does have its own dental school though so that might help a little with getting into dental school there and you could always do some research or volunteer at the dental school to boost your application which could be a help. I don't think there is enough seperation between these two schools reputation wise that would really boost your chances going to one over the other though. Overall, you should probably just choose the school that fits you best.
Go wherever you like. It doesn't matter as far as getting into dental school goes. It only matters that you do well on the DAT and get a good GPA. I hope you have a blast in college, good luck!👍
