100% more stain removal in 3 days*

Deep cleaning needs a special approach and this C3 brush head uses a cluster of dense, stiff bristles at its centre in a pentagonal shape to whiten and polish your teeth, for up to 100% more stain removal in three days. It also removes up to 10 x more plaque than a manual toothbrush.

Sonicare Fluid Action

Sonicare Fluid Action

Philips Sonicare toothbrushes gently yet effectively clean and care for your teeth and gums with up to 62,000 bristle movements. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.

Help protect your gums with our pressure sensor

It's easy to brush too hard, so this Philips Sonicare toothbrush has a smart optic sensor to detect excessive pressure. If you're brushing too hard, it will let you know trough gentle vibrations as a reminder to ease off the pressure to help your gums stay protected.

Did you know brush heads become less effective after three months? Dental professionals recommend changing your brush head regularly, so that's why Philips Sonicare toothbrushes have a brush head replacement reminder. It tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one.
