The Tooth Guardian is a concept designed by Yu-Hsin Lin, Chu-Che Chang and Shang-Hsuan Lu, to help cut down on unwanted dentist visits by integrating a camera system into your toothbrush. The camera takes a look at your chompers while you brush, and displays an image of what it sees on your bathroom mirror - the idea is that you would see where you're missing in your daily brushing routine, or be able to catch things like cavities early.
An LED light on the brush illuminates your mouth, a micro CCD captures what's going on inside, and a UV light sterilizes your toothbrush when you're done.
The Tooth Guardian is currently just a concept, but certainly an interesting one. What do you think? Would you want to see your teeth while you brush?
