Going to the almost dentist

As a dental student, I get free cleanings at school. And my roommate, who is a 3rd year dental student, is in need of patients. So it was a win-win situation today when I went in to get my teeth cleaned by my roommate. I've never been personal friends with my previous dentists, so it was an interesting experience having a buddy get all up in my grill like that. I apparently have some weird, but "beautiful" (says the attending dr, who was overseeing everything) teeth. A couple of my teeth are rotated, I have something in one of my sinuses (the attending is making my roomie look this up and talk to some pathologist about this... sorry, J), I have an extra bone in my palate, and an unexplained indentation on one of my molars. And I have 2 caries/cavities. :( So I have to go back for another appointment. This is by far the most comprehensive check up I've had but in all honesty, it was fun! What's a better way to learn about teeth but to look at your own?
