If there's one thing we're lax on besides alimony payments, it's flossing. Though we are made well aware of the benefits every time we step into the dentist's chair, it is just such a pain. Maybe if you hit your wallet hard enough, you'll find the motivation you need to clean beneath your teeth. That's where the Phillips Air Floss comes in. As an alternative to cleaning between your teeth with white string, the AirFloss sends air and water between your teeth knock out the dirt that creeps between the crevices. Even the most generous reviews maintain that this device is no better than flossing, but since you don't floss anyway, just focus on the fact that this machine beats brushing alone.
