So what are you doing to my gums?

Matt and I have volunteered to help the acquaintance of a friend with her last semester in dental hygiene. We're her guinea pigs and final exam, which is really interesting. We qualified because Matt has never been to the dentist and I've only ever been once. She needed some volunteers that needed work done, heh.
