Everyone cleans differently, so we designed this brush head with multi-angle bristles to keep plaque removal on course no matter your technique. Our All-in-One brush head delivers range-leading cleaning and removes up to 20x more plaque than a manual toothbrush, even in hard-to-reach areas.
Our All-in-One brush head includes triangular bristles to increase surface contact and clean away stains more effectively. The results speak for themselves, with up to 100% more effective stain removal in less than two days.*
The side bristles of this brush head are extra-long to keep your gum line brushed even while you're focusing on your teeth. The result is up to 15x healthier gums in six weeks.*
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.
All Philips Sonicare brush heads are meticulously designed and clinically tested. So you can be sure they meet the highest standard in quality, safety and performance.
Did you know brush heads become less effective after three months? Dental professionals recommend changing your brush head regularly, that's why Philips Sonicare toothbrushes have BrushSync technology. 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.
