Get pigs feet and practice sutures techniques!! We did it and it was a blast. It was part of an event we did that involved other little things but we had a dentist present to bring supplies and showed us techniques
I would also look at raising money for a free dental clinic nearby if you can.
Maybe a field trip to a dental lab?
Or to a dental school for a tour if there is one within a reasonable distance.
See if you can get an adcom out there? I know pre-med people would like that (Actually what got me to switch!)
