Dental and Dental hygiene clipart?

[speedmedia]

Hey all,
I am working on a little project for a friend of mine to teach the importance of dental hygiene to some k-5 students. Wants something cartoony and fun but has very small budget. Would like to find something decent and fun, need a lot of different images. Don't have budget to draw everything from scratch and many of the clipart sites I am finding either they are terrible images or they are very expensive..

Anyone know of anything out there that is simple, cheap and easy? lol

I know do you want fries with that? I do it fo da kids!

Thanks,
Kurt
