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.
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.
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.

My teeth have never felt cleaner!
Takes a couple of hours to charge but the toothbrush holds its charge extremely well! It definitely surpasses the 14 days it claims! My teeth/mouth has never felt as clean since using this toothbrush! My teeth visibly appear whiter and brighter. Friends and family have commented on how white my smile looks since using this toothbrush. The coverage detector allows me to clean my teeth more thoroughly than my previous toothbrush, as I’m able to focus on the areas I’d been neglecting prior. The pressure indicator is extremely useful as it allows me gauge the optimal amount of pressure on my teeth, which I assume will help also help protect my enamel. I’d 100% recommend this toothbrush if you really want to upgrade your oral hygiene routine and care for your mouth!

Amazing tooth brush well worth upgrading
A Great upgrade well made and very useful with the screen that shows how your teeth brushing session was on different parts where I need to brush more. The colour at the bottom that prompts for less pressure or more is very helpful. I have the older model and this is a great upgrade. Cleans teeth really well with the ultrasonic technology. Has many options of what pressure you want or what mode of cleaning. The brush head is great also instructions are very clear. Easy to set up and charging is easy put in the cup and it starts charging.

Game changer for that fresh from the dentist feel!
I am SO happy to have this product in my life and I am definitely looking forward to using it for many many years to come! 🙌✨ The brush head surface is noticeably larger than my previous electric toothbrush that I used to use, which makes brushing feel way more effective and effortless. That Sonicare technology is unmatched- my teeth feel insanely clean, literally like I just walked out of professional dental polish! 🦷 The vibration power and features are top notch, plus the built-in pressure sensor keeps you from pressing too hard. Recharging is super easy, and the sleek travel case makes taking it on the go a breeze. A total five star and my absolute new go to! ⭐️⭐️⭐️⭐️⭐️
