Getting your child to brush for two minutes twice a day can be a disaster. Philips now has an app that will (hopefully) make it easier.
In Brush Busters you can save the teeth of two animated characters. Every time you brush your teeth for two minutes, a tooth comes in and of course there are also instructions on how to brush. You yourself have insight into how often and when your child has brushed.
Download the app for iPhone or Android.
