Not for the ticklish. A new toothbrush of sorts, call the Blizzident, is shaped exactly like your teeth and claims to clean every last tooth in only six seconds. To get one, you go to a dentist and have an impression made of your teeth. The impression is then sent to a lab where the results are digitized using 3-D scanning and 3-D printing technologies and then transformed into your own personal Blizzident. As of now, the furry tool costs $300—perhaps worth the price tag to ensure your roommate isn't borrowing your toothbrush on the sly.
