I know here at UCLA spring-ish there was flyers up for free dental work, essentially the people who were graduating needed patients for their final exam, now you had to go and be pre-screened (whatever that entailed) to get the free dental work, but it was from people who were about to graduate. So it also too a little longer (you had to go in, be screened, go home, be accepted, come back at a later time). YMMV. Personally I would had taken them up on the offer, if I wasn't still under my parents health insurance.
