CES 2015: Toothbrushes get smarter

Oral-B toothbrush is Bluetooth-enabled

Remember when electric toothbrushes were cool? Well, they've become even more technologically advanced, with several exhibitors at the Consumer Electronics Show showing off smart toothbrushes that monitor how well you're brushing and log your data for you.

The Oral-B SmartSeries toothbrush is Bluetooth-enabled and works in tandem with an app on your smartphone.

A pressure sensor stops pulsations when you brush too hard, and offers tips on your phone once you're done brushing.

The app also shows you news articles at the bottom of the screen to keep you entertained during your recommended two minutes of brushing.

Price: $159.
