Meet the Philips Sonicare for kids: an app-enabled toothbrush that shows your kids how to brush their teeth properly and independently. It connects to your smartphone via Bluetooth and keeps track of brushing time and frequency. Since it delivers 500 strokes per second, it is much more effective than manual toothbrushes.
With KidTimer and KidPacer, your child is going to have an easier time spending proper time on each quadrant of his/her mouth. Sonicare for kids goes easy on teeth and soft tissue. More information is available here.
