Using an iPhone to help clean our teeth with Oral-B's new toothbrush (pictures)
Oral-B's new connected Genius 9000 toothbrush uses your phone's camera to monitor how well you're cleaning your teeth.
Not brushing properly? Oral-B's latest smart brush, the Genius 9000, is here to teach you the key to sparkling gnashers.
It ropes in your smartphone to help -- stick your phone on your mirror with the included bracket, and the toothbrush's app uses the front-facing camera to gauge whereabouts in your mouth you're brushing, and for how long.
