All-in-One brush head for complete care

Clean without compromise with the A3 Premium All-in-One brush head. Our all-time best has angled bristles to help remove up to 20x more plaque even in hard-to-reach areas*. Triangular tips work to remove up to 100% more stains in less than two days***. And longer bristles clean deep for gums that are up to 15x healthier in just two weeks**. All that without ever switching brush heads. Did you know: brush heads become less effective after 3 months of use? Our BrushSync feature can remind you when it's almost time for a replacement.

Sonic brushing: the masterclass in effective cleaning

Helps you improve your brushing technique

Helps you improve your brushing technique

With an electric toothbrush, it's best to let the brush do the work. We've built a sensor into the handle that works with our app to help you reduce excess scrubbing. This way, you can improve your technique and get a gentler, more effective clean.

Smart guidance for gentle care

Smart guidance for gentle care

You might not notice when you brush too hard, but your DiamondClean Smart will. If you use too much pressure, the light ring on the end of your handle will flash. This is a gentle reminder to ease off the pressure, and let your brush head do the work. 7 out of 10 people found this feature helped them become a better brusher.

Automatically selects the best mode for you

Automatically selects the best mode for you

You'll always get the best possible clean with our BrushSync mode-pairing feature. Smart brush heads ensure you're using the right mode and intensity for the best possible clean by selecting the optimal brushing mode and intensity level in combination with your brush head.

Make sure you're getting the most from your brush head

Make sure you're getting the most from your brush head

Brush heads wear-out over time and become less effective at removing plaque. With smart brush head recognition you'll never lose track of when to replace your brush head. Your toothbrush tracks how long and hard you've brushed with each brush head, and will alert you when it's time to replace. You can also monitor the lifetime of your brush heads in the Philips Sonicare app, and even order replacements so you're never caught short.

Up to 4x more surface contact**** for an effortless clean

Up to 4x more surface contact**** for an effortless clean

You get a personalized clean every time you brush with our adaptive cleaning technology. Soft rubber sides flex to let C3 Premium Plaque Control adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 4x more surface contact than a regular brush head**** for deeper cleaning in hard-to-reach areas.

Premium charging glass and travel case

Premium charging glass and travel case

Not only does your glass charge fit stylishly into your bathroom, it also doubles as a rinsing glass. Enjoy two weeks of regular use from a single full charge. Our premium travel case lets you store your toothbrush hygienically when you're on the go.
