Important info


What is Philips Sonicare?
Our sonic technology supported by contact of the specially designed soft bristles creates fluid action that gently reaches deep between teeth for a superior clean you can see and feel.
Smart Brush Head Recognition
Smart Brush Head Recognition ensures you are getting the best performance with your brush head. When placed on the handle the microchip in the brush head will automatically select the optimal mode and intensity that is best for that brush head.

3 in built Smart Sensors
The pressure sensor ensures that you are not damaging your teeth and gums by brushing with too much pressure, the location sensor enables you whilst connected to our Sonicare App to see the areas that you have and have not brushed to ensure that you cover your whole mouth and the motion sensor alerts you when you are not using the correct brushing technique.

Smart App for Real-time Feedback
Connect via Bluetooth to our free Philips Sonicare App to get real-time feedback on your brushing, track where you have/haven’t brushed, highlight your trouble/focus areas and improve your brushing technique. The App highlights trouble areas on your 3D mouth map, and reminds you to pay extra attention to these areas.

Never miss a spot
Thanks to our smart location sensor, you'll always know where you've brushed, and where you haven't. Real-time tracking on the Philips Sonicare App that lets you know when you've achieved a thorough clean, and coaches you to be a better, more mindful brusher.
