Brushing manually with the wrong technique and not for long enough does not remove plaque effectively. This allows harmful bacteria in the plaque to damage teeth and irritate gums.

At night, our mouths are vulnerable. While we sleep, saliva flow slows down, allowing bacteria left behind to multiply more easily.

Brushing properly before bed keeps harmful bacteria under control and helps good bacteria maintain a healthy mouth while you sleep. Philips Sonicare is the #1 dental professional recommended sonic toothbrush brand worldwide.
Sonicare Fluid Action supports the bristles to clean by driving fluid between teeth & along the gumline.
Up until now brushing has been guesswork. But our NEW Next-Generation DiamondClean’s real-time coaching and smart display shows areas you’ve missed, meaning complete care is now 100% visible.
