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.

A stylish and effective toothbrush loaded with handy tech features!
I absolutely loved using this toothbrush - it’s a huge upgrade on the earlier Sonicare models and the smart features are an absolute joy. It charges quickly and gives a solid indicator of how many uses remain so that you’re not caught out especially when travelling. Though the charging case definitely helps with this! The charging glass design also looks great in the bathroom - just place it somewhere secure so that you don’t knock it over! The fact that you can drop the toothbrush into this anytime also helps with keeping the charge topped up rather than waiting for the battery to run low. The device itself has a stunning matte finish which feels good in the hand, it’s lightweight but sturdy and a perfect size to grip easily and aid with manoeuvring during use. During use the toothbrush is fairly quiet for such a powerful piece of kit which can sometimes be really noisy, and the included brush head was very effective. The device is compatible with the other Sonicare heads in the range meaning you can choose the right replacements to suit your needs without worrying whether they will fit. Onto those smart features, the pressure indicator light at the base of the brush is great for instant feedback with the bright colours easy to identify. I was slightly dubious about the need for a connected app but this is well-designed and gives genuinely useful insight into how effective your brushing technique is over time. This was easy to use and understand, immediately providing benefit so I was quickly converted! The reminders to change your toothbrush head and direct links to order replacements are also very handy. The touch led screen is easy to use and a really nice way to scroll through options and modes in a clear and user-friendly way. Overall this toothbrush was and continues to be a pleasure to use!

Allows you to perfect your cleaning technique and makes brushing effortless !
Best toothbrush I have ever used. It really allowed me to master my brushing technique with its pressure detection and area detection! It has an app so you can see live your brushing technique my teeth have never felt cleaner. The included brush head is ideal! Has a lot of different cleaning options and sensitivity settings. The carry case allows the battery to be charged easily when you travel along with the included glass cup which actually sits on a charging base that is USB powered so when ever you are done your tooth brush is wireless charged ready for the next time. I’ve used this over a period of 3 weeks and can say I’ve been so impressed ! It’s also really durable and light in the hand

A game changer in my oral health routine!
I’ve been using the Philips Sonicare 9000 DiamondClean for a while now, and it has genuinely transformed my daily dental routine. The standout feature for me is the real-time mouth mapping on the handle. It highlights the areas you’ve missed and vibrates when a spot has been properly cleaned, which made me realise I’d been completely neglecting the insides of my teeth until now. The battery life is outstanding. I managed to take it on a two week holiday in its travel case without bringing the charger, and it still had power left when I returned. I also really appreciate the adjustable vibration intensity, as it makes brushing much gentler in sensitive areas. Overall, it’s an excellent electric toothbrush that has changed how I care for my teeth. I’m so impressed that I’m even planning to buy extra brush heads for my children so they can benefit from a better clean as well. Highly recommended!
