jojo,
Yes, Tufts has a rigid screening process prior to interviewing so if you get an interview they are pretty serious about you. Also, Tufts is one of the best dental schools in the country. I did not interview at Tufts since my interview letter came after Dec. 2 and I already got accepted to PENN. However, I've only heard good things about it except (money and location, blah blah). Everyone of my friends was very impressed, and I think you will be too.
Good Luck,
