LAS VEGAS — Want to avoid gingivitis and tooth decay? There’s an app for that. More than one, actually, and they work with Bluetooth-equipped toothbrushes to help ensure you’re properly cleaning your choppers.

The app for Oral-B’s electric Bluetooth toothbrushes is designed to develop good brushing habits and keep your teeth healthy.

“We have a product that will work — if you use it,” Oral-B rep Kris Parlett told Cult of Mac during International CES.

Last year we featured the Bluetooth fork that vibrates when it thinks you’re overating — and this year’s wackiest CES unveiling so far goes to the Bluetooth toothbrush (Bluetoothbrush?).

Shown off for the first time at a preview event on Sunday, the toothbrush (made by French startup Kolibree) aims “to reinvent oral care” — according to company co-founder Loic Cessot.
