I was in your shoes a few weeks ago trying to decide between Temple and Tufts. Luckily, I got into VCU which was my top choice so I had no further decisions to make. However, I had it down to just Temple seeming a bit more comfortable to me then Tufts. I was afraid of Tufts because (1) I didn't want to take a course on how to commute in Boston, (2) Preclinical experience would have been jeopardized due to the vertical expansion, (3) Taking an elevator 8-10 times daily seemed like a ride I wasn't willing to take for 4 years, (4) Crowded hallways exacerbated my claustraphobia, (5) Curriculum didn't attract me as an effective way to study for the boards. In other words, I study better by myself with less classes rather then a heavier courseload with less private time to study for the boards. I know they rank higher then the national average but I just clash with that board-prep style,, (6) General feel of the area was that everyone was worried about themselves (i.e. profile, image, social status) then they were about others.
I liked Temple for all the same reasons but on the other side of the coin. I really liked how the courseload was formatted to help students learn the important things about dentistry without trying to bedazzle students with regards to the academic reputation of the school; I want to learn, not be bedazzled. I don't know, I guess I just felt more comfortable at Temple then I did at Tufts and had I not been accepted to VCU I would have gone there in a heartbeat. Good luck in your decision.
