The brush is connected by Bluetooth to your smartphone, and thus to the network.
It sends your brushing activity to an application on the smartphone, tracking whether you follow the 2-minute rule and if you brush hard, but not too hard.
If your results are good, a message pops up on your smartphone: "Congratulations: your teeth are shining."
The information is also shared on social networks or directly with your dentist.
It will be sold for $300, coming this June.
