Philips Sonicare ProtectiveClean 4300 HX6800/35

With the Philips Sonicare ProtectiveClean 4300 HX6800/35, you and your partner will never brush with a worn brush attachment. This toothbrush measures your brushing behavior and indicates with an indicator light that it's time to replace the brush attachment. That's useful, because you don't have to keep track of whether you've been brushing for 3 months. Switching to an electric toothbrush for the first time? Use the EasyStart program to slowly get used to brushing. To help you stick to the recommended daily brushing time, this toothbrush has an interval timer. This'll automatically signal you when you need to change zones.
