Not Just Wrists: The New Look of Fitness Gadgets

Kolibree claims that this is the world's first connected electric toothbrush. Whether or not the Bluetooth-enabled brush and app companion can replace your dentist remains to be seen.

Kolibree offers dental-health-conscious users feedback on their brushing habits. The app, which will launch July 2014, rates the effectiveness of each brush and tells you stats about brushing time and teeth coverage. Kids get awards and badges as they improve.

The electric toothbrush will ship later this year for about $100 to $200.
