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 highlights any areas where you need to reduce pressure in the future. It provides you with personalised brushing guidance for ultimate care - all in the palm of your hand.

Premium and lightweight
The Phillips Sonicare Diamond Clean 8500 is AMAZING!! I have used a basic electric toothbrush for years. This… absolutely shines way above and beyond! It was packaged great and felt like the premium product that it is. Everything in individual boxes (It felt like one of the ‘unboxing’ videos my 12 year old watches). The toothbrush itself is very lightweight yet remains premium. It has a touchscreen display to swipe between options, a ‘confirm’ button and of course the on/off switch. You then link the toothbrush via Bluetooth to the app. There are clear instructions within the box to explain how to set this up. The app took a minute to set up. It features different settings for the toothbrush including clean, diamond clean, whitening etc. You select what you want. It gives daily data on how well you’re brushing your teeth. If you press too hard it gives a warning light, if you continue to press too hard, the toothbrush adapts for this. The brush head feels great, not too firm nor soft. The data tracking on the app is great and protective daily brushing align with flossing and other dental hygiene too. I am very impressed with this product and would certainly recommend this as 5* and will be encouraging my husband to purchase one.

Makes your mouth feel extra clean
Really impressed with the Phillips 8500! It has a strong, powerful clean & I love that it guides you where to brush, making it easier to give your entire mouth a thorough clean. After brushing my teeth and mouth feel noticeably fresher and extra clean! The set up was extremely simple! Just had to unpack the items and follow the guide which was included in the unboxing. I also really like the additional accessories that come with it such as a travel charger! It feels like a premium tooth brush. Would highly recommend
