Hey freddy,
Sam Spade is right on about my school and our research opportunities and he makes some very good points about finances as well. And no matter where you go, you will be so busy in dental school that which city you are in isn't as big a deal as you might think, as long as you have some cool friends in dental school to enjoy your time with.
I'm not hurt if you don't choose my school or feel it's not a good fit for you (although I have been very happy with UB). However, you also got into UConn. UConn has a big focus on dental research and has lots of active research going on. And if you ultimately want to specialize, they have good placement rates for that too, especially with their P/F system and consistently fantastic board scores. And it's a state school, so it'll still be cheaper than Penn or Columbia. Yeah, it's in Farmington, but like I said, you will meet people who make dental school fun. Every UConn dental student I've met through ASDA & research have always been real awesome and happy with their school.
Disclaimer: If your family is loaded and can foot the bill for a private school without thinking twice, then ignore everything Sam & I have posted and pick the Ivy $chool that suits you.
However, if you are borrowing your way through school, go where the debt will be less. This is the advice I was given by many dentists (mostly recent graduates) when I debated between UB & Penn. Even a Penn grad (my first orthodontist) told me to go to UB b/c of the debt factor. Now, as a senior dental student, I am very glad I listened to them. They really did know what they were talking about. Not having the extra debt from attending Penn has made my decision to specialize easier, b/c I am free to apply to any school I want and not have to agonize over going into even more debt with specialty training.
Unless you specialize in Pedo or a 4-year Oral Surgery program, chances are you will be borrowing more money if you go through with specialty plans. All the other specialty programs now have to charge students tuition to attend with GME funding gone. Even many 6-year Oral Surgery programs charge for the 2 years of med school you have to attend. Attending somewhere like NYU or Pacific for 2 years of Ortho will easily run you $100,000 in tuition (for two years) and that's not even including what you'll need to borrow to live in NYC or SF.
For all the pre-dents: No matter where you go, you can always enter school with aims to specialize. However, you have to remember you are going to dental school and will graduate as a dentist. Something can happen on the path to specializing and you might end up working as a general dentist for a while before getting to specialty school (family, relationships, $$$, applications, grades, anything). You have to enter dental school knowing that you can be happy working as a general dentist or else you will be miserable through your four years in dental school and in your career as a dentist.
