I'll almost guarentee that if you meet 5 of the academics, especially the faculty that are in the over 50 set that you'll see atleast 1 "dental disaster" amongst them.
For example, the Dean of my dental school when I was there, a periodontist by training, had blatant and obvious perio disease. Don't sweat it, if you are asked you can say something to the extent of "I'm planning on trying out the latest and greatest dental advances on myself before I try them on my future patients! 😀
