Remove 20x more plaque, enjoy up to 15x healthier gums in six weeks, and see 100% more stain removal in less than two days versus a manual toothbrush.

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.
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.
Smart pressure feedback helps you brush with just the right pressure. During brushing, the light ring gives you instant feedback on how much pressure you are using. It glows green when you’re using the right amount of pressure, pulses purple with a gentle vibration if you’re pressing too hard, and slowly fades to purple when you’re not applying enough pressure. As a result, you get the best cleaning results while protecting your teeth and gums. At the end of your session, the handle’s display shows a mouth map highlighting where you may need to adjust pressure in the future.
After brushing, a glance at the handle's display will show you post-brushing feedback. The mouth map indicates any areas that need a retouch as well as areas where you need to reduce pressure. It provides you with personalized brushing guidance for ultimate care - all in the palm of your hand.
This electric toothbrush uses our Next-Generation Sonicare Technology which delivers our most reliable and consistent brushing for excellent results every time. The motor adjusts power automatically so there is zero drop in performance when you reach those harder-to-clean areas. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between the teeth and along the gumline.
Easily swipe to select your ideal mode, intensity and instant feedback directly using the handle's color display. Choose between: Clean, Deep Clean, White, Gum Health, Sensitive, Max Care, Comfort and Polish modes. Plus three different brushing intensities: high, mid, and low.
The Sonicare App, paired with your Sonicare toothbrush, feels like having a personal dental coach by your side. The app provides real-time feedback and coaching with a dynamic visual mouth map, includes tips to improve your brushing technique, and tracks daily oral care routines. See your progress in a personalized dashboard. Celebrate your wins! It’s a daily self-care companion that empowers you to smile with confidence.
The new Sonicare DiamondClean comes with a glass charger, premium finishing and an aesthetic design that elevates your brushing experience. For life on the go, the Prestige travel case doubles as a charger, ensuring your toothbrush stays charged, wherever you go.
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 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.
