I spy with my little eye-tooth: The Oral B smart toothbrush

Joining our list of "things that shouldn't connect to your iPhone, but for some reason can," we bring you the Oral B smart toothbrush. This new device enables your dentist to spy on your mouth for the greater good. Oral B's new iOS-compatible Bluetooth-linked toothbrush tracks your brushing habits and collects data on every brush stroke.

A free companion app for iOS and Android will offer step-by-step guidance on brushing -- and possibly on how to breathe in and out, how to brush your hair, and how to walk across a room.

In related news, the NSA has issued a public statement that they will only monitor brushing metadata and will not seek specific toothbrush habit information without a warrant.
