Guides you to brush with the right pressure

Guides you to brush with the right pressure

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.

Brushing insights in the palm of your hand

Brushing insights in the palm of your hand

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.

Excellent cleaning performance with smart features that make brushing effortless

The Philips Sonicare 8500 is a fantastic toothbrush. This is the first time I’ve used a sonic toothbrush, and I’ve been really impressed with how well it cleans. It leaves my teeth feeling noticeably clean and fresh after every use. One of my favourite features is the visual pressure indicator. It makes it very easy to see whether you’re applying the optimal amount of pressure while brushing. This is particularly useful when you’re new to using an electric or sonic toothbrush, as it helps you develop the right brushing technique without having to guess how much pressure to use. The charging system is another great feature. The included glass can simply be left in the bathroom, and when the toothbrush needs charging, you just place it in the glass and put the glass onto the wireless charging pad. It’s a really convenient and tidy setup, and there are no cables or connectors to worry about in the bathroom. The travel case is also well designed. It feels sturdy and provides good protection for the toothbrush, while still being reasonably compact. I particularly like that the brush head can be stored underneath the toothbrush, which keeps the overall case size down. It should be ideal for taking the toothbrush on holidays or business trips. It will definitely be durable. The brush-head replacement reminder is another feature I really appreciate. Rather than simply reminding you after a certain amount of time, the toothbrush keeps track of your usage and displays a countdown showing how many brushing sessions you have left before the brush head needs to be replaced. It takes the guesswork out of knowing when it’s time for a new one. The Sonicare app is excellent and adds a lot of extra functionality. The guided brushing mode helps you make sure you haven’t missed any areas of your mouth, which is particularly useful for improving your brushing habits. The app also offers smart ordering, meaning you can arrange for replacement brush heads to be ordered before your current one needs replacing. It’s a thoughtful feature that means you’re less likely to find yourself without a replacement when you need one. The battery life has also been excellent. It lasts long enough that I don’t have to think about charging it regularly, and the wireless charging glass makes topping it up really convenient. The toothbrush also feels powerful without being uncomfortable. The sonic vibration is noticeably different from a traditional electric toothbrush at first, but I quickly got used to it. It feels fast and thorough, and you can really feel the brush working across your teeth, while the pressure indicator helps prevent you from pressing too hard. Overall, I’ve been extremely impressed with the Philips Sonicare 8500. The combination of excellent cleaning performance, pressure guidance, convenient wireless charging, a well-designed travel case, brush-head reminders and the accompanying app makes it feel like a very well thought-out toothbrush. As this is my first sonic toothbrush, I wasn’t sure how much difference it would make compared with a traditional electric toothbrush, but I’ve been genuinely impressed with the results. It’s easy to use, packed with useful features and, most importantly, leaves my teeth feeling exceptionally clean. I would definitely recommend it to anyone looking to upgrade their toothbrush.

Gentle and powerful. Properly cleans the teeth.

I wasn’t sure how different this would feel from my previous electric toothbrush, but I noticed the improvement straight away. My teeth feel properly clean and smooth after brushing, while the A3 head is still gentle on my gums. The pressure light is probably my favourite feature because I sometimes press harder than I realise. The different modes and intensity levels are useful, although I mainly use Clean mode. The handle feels comfortable and secure in my hand, the controls are simple, and the black finish looks very smart. Battery life has been reliable so far, with no charging or performance issues. I also like the charging pad and travel case, as they make the whole set feel practical as well as premium. It is more expensive than a basic electric toothbrush, but the cleaning performance and useful features make it worth the money for me. Very pleased with it. The vibration intensity is perfect as well.
