Or you could listen to someone who has only been at the school for a couple of months
Anyways to the OP, do what I did when I was asking myself the same question....talk to people in the dental community within Boston. My family lived in Boston for 5 years, and when talking to people in the dental community, the consensus was unanimous.....Tufts is the WAYYYY better dental school in Boston. To be honest, I dont even think I heard one person tell me to choose Boston over Tufts.
But dont take my word on it....if you are serious about your question, try and talk to grads from both schools who are practicing now....try and go out to the dental community in Boston and ask them yourself....I will bet my right leg that you will get the same consensus....
its a no brainer....Tufts.
