Next-Gen Sonicare Technology
20 x more plaque removal*, gentle on gums
Feel our best clean with the A3 All-in-One brush head. Remove 20 x more plaque, enjoy up to 15 x healthier gums in six weeks and see 100% more stain removal in less than two days versus a manual toothbrush. Enjoy a gentle yet effective clean for your teeth and gums with 62,000 bristle movements per minute.
No missed areas with instant coverage feedback
The toothbrush closely follows your progress to help you clean thoroughly. The light ring at the base of the handle glows yellow when a segment of your mouth still needs attention. When it glows blue, the area is clean and you can move on to the next segment. Finished cleaning? A glance at the mouth map on the handle's display will show you any areas that need a touch-up.
Automatically adjusts based on your brushing behaviour
SenseIQ Adaptive Intensity helps protect your teeth and gums by automatically adjusting to your brushing style. When Pressure + SenseIQ is activated, the toothbrush senses pressure, motion and coverage up to 100 times a second and reduces the intensity if you brush too hard.
