Product description

The DiamondClean Smart is our best ever toothbrush, for complete care. Four high-performance brush heads let you focus on all areas of your oral health, and our Smart Sensor technology gives you personalised feedback and coaching. The DiamondClean Smart comes with our three best brush heads plus our TongueCare+ tongue brush, so you get exceptional results: our Premium Plaque Control brush head removes up to 10 times more plaque from hard-to-reach areas. Store your spare brush heads hygienically in our handy case. It's the perfect accessory—and available exclusively with this toothbrush. Wondering which mode and intensity you should use? A microchip in your brush head tells your DiamondClean Smart which one you're using. So if you click on a gum-care brush head, for example, your toothbrush knows to select the optimal mode and intensity to provide a gentle yet effective clean for your gums. All you need to do is to press the power button. Our smart sensors take the guesswork out of brushing. The location sensor shows you where you’ve brushed, and more importantly, where you’ve missed. If you brush too hard, the pressure sensor will trigger a light to flash, so you know to ease up on the pressure. And if you start scrubbing, the scrubbing sensor reminds you to let the brush do the work. Perfecting your brushing technique and building healthy habits have never been easier. DiamondClean Smart comes with five modes which cover a range of brushing needs: Clean mode is for exceptional daily cleaning, White+ is for removing stains, Deep Clean+ gives you an invigorating deep clean, Gum Health provides a gentle yet effective clean for gums, and Tongue Care is the perfect mode for cleaning your tongue. It breaks up tongue debris and sweeps away bad-breath bacteria. Three intensities allow you to choose between a higher setting to boost your clean and a lower one for more-sensitive mouths. Set oral-health goals, and we’ll help you reach them with personalised coaching. And if your dentist has pointed out any trouble spots, just put them into your 3D mouth map so we can remind you to give them extra care every time you brush. Our deluxe travel case is also a charger. You get up to two weeks of regular use from a single full charge - Simply put it into the sleek glass charger after brushing, and it instantly starts charging. Your glass charger makes a stylish addition to your bathroom—and it doubles as a rinsing glass.

Amazing! Love it! It arrived earlier than expected The toothbrush brush was greatand the app is the best too, it’s helping me track everything, the sensors told me when I was doing too much pressure, it timed the every section of my mouth and has 3 sessions for tongue washing. I couldn’t be happier. Let’s see how it goes after a week.

It’s tough to justify the cost but this toothbrush has truly change the frequency and duration of my brush time. My mouth feels so much cleaner and the integrated smart functionality for me is a huge plus. I upgraded to this tooth brush from my previous Sonicare toothbrush after 5 years because the motor had started to wear down. I imagine this toothbrush will last just as long! Great buy!

Excellent toothbrush that does a great job thoroughly and accurately cleaning all of my teeth, "leaving no stone unturned" so to speak.

Has a good range of options for the type of Teeth cleaning you want/feel like you need to use that night, and actually achieves noticeable results (whiter, cleaner teeth) the next day, or at the very least over a period of a week.

My primary issue with this product is that the model I was issued broke after 5 months - the tip fell off, which apparently is a common problem. As a result, the toothbrush was almost completely unusable (very annoying as I already have weak enamel), and I am currently involved in getting a replacement. So, I would strongly advise that everyone who buys this product makes sure to activate the warranty and keep their receipt, just in case the same problem arises. Also, before the tip fell off the toothbrush, it started making horrible, loud noises (instead of the quiet, vibrating sound it usually makes), and I had a feeling it wasn't working as effectively, which I should have taken as an early warning sign.

Overall, 5 stars all around, except for the build quality and (apparent) manufacturing standards, which I would rate 2/5

Does this actually clean any better than a manual toothbrush? Probably not, but this electric toothbrush is an experience. This is designed to be coupled with the Sonicare app which tracks your brushing around your mouth. Personally I think this is the best feature; showing you exactly where you need to brush and giving the whole process some order.
There are a bunch of different modes and brush heads; personally I dont notice the difference between the heads themselves, but having a few of them means they will last you ages based on the amount of brush life each head has.

This is very much an indulgence thing at this price point, but if you have the money, this is a great product with great features that help with the management of good dental hygiene.

This was my second Phillips DiamondClean.

The brush makes a noise but doesn't vibrate. Died after 1.5 years.

Had another DiamondClean previously. Just wouldn't turn on. Died in a year. Also, the brushheads are expensive, and the App doesn't track well

Meanwhile, my original oral-B lasted years (and eventually, I only threw it out because the battery totally died). My second one still works (after years), but I wanted something which was better.

Returning my faulty diamondClean, and already ordered a OralB IQ Series 9 (and its already WAY better at tracking, and at brushing)

My expensive toothbrush suffers from the "death rattle", which seems to be a common problem with Sonicare models. It lasted only for 1.5 years.

Best toothbrush I have owned to date. The app is also good and I feel my teeth are much cleaner after I started to use it.

I love everything about this product, from the design and features to the performance. Having previously had another brand's Electric Toothbrush, which i was happy with, I decided to upgrade to this. What i like about this is the traditional brush head design and the easy brushing motion for a natural feel of a traditional brush. The sonic power is amazing! I thought my other brush cleaned better than a normal toothbrush, but this is another level again.
