I hate to be negative, but I feel I need to share some information I have regarding Tufts since you're asking for advice. There are always pros and cons to decisions, so let me share what I've heard with you and you can use it/ditch it as you wish.
My Father is a dentist and has several good dentist friends whose children went to Tufts Dental School (at least three separate cases) where they had to do an extra year at Tufts because there were not enough patients in the clinic for them to get enough credits to graduate. Thus, they had to do 5 years in dental school, not just the regular 4 (ie. more time, maybe more money- not sure about that part). I did not apply to Tufts as a result, but have been offered an interview at BU. Just wanted to share with you what I know of the school, as if I were in your shoes, I'd want to know all I could before making this important decision.
