** vs. a manual toothbrush in Gum Health mode.
***vs. a manual toothbrush in White+ mode.
Healthy habits are a breeze with real-time feedback
Our smart sensors take the guesswork out of brushing, giving you personalized coaching and feedback. The location sensor shows you where you’ve brushed, and more importantly, where you’ve missed. 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.
Via the free Philips Sonicare app, experience 100% visibility of your trouble. Track your progress and improve technique with your personalized 3D mouth map. Allow our Touch-Up feature to help deliver a successful clean in every session, with no missed spots.
Track your Brush Head’s Effectiveness
Over months of normal use, brush heads gradually wear down and become less effective. The smart brush head performance monitor tracks the brush head’s effectiveness based on your actual brushing time and pressure. Replace your brush head when the icon on the handle lights up.
Smart mode pairing, and brush head recognition
Wondering which mode and intensity you should use? Wonder no longer. 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 for that brush head. All you need to do is to press the power button.
Pressure Sensor
You might not notice when you brush too hard, but your DiamondClean Smart will. If you use too much pressure, the light ring on the end of your handle will flash. This is a gentle reminder to ease off the pressure, and let your brush head do the work.
14 day Li-on battery
Enjoy up to two weeks of regular use from a single full charge.
This product has a 90-day money-back guarantee and 2 year warranty.
Function & style in a handy glass, deluxe case for on the go
Charging your toothbrush has never been easier. 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
Our premium travel case lets you store your toothbrush hygienically when you're on the go.

- Reviewed in Canada on February 1, 2019Verified PurchaseAfter my last electric toothbrush died I did some research to find the 'best' electric toothbrush out there and stumbled across the Philips DiamondClean. This toothbrush is amazing! Out of all the previous electric toothbrushes I've used this one has got a LOT of power and it feels like I just left the dentist after a cleaning! You'll notice that you'll have to clean your mirror more as toothpaste is easily splattered around with the power of the toothbrush (perhaps its a brushing error though).
I tried the bluetooth app on my iPhone for a few brushes but didn't see the benefit for me. The toothbrush comes with 3 separate brush heads depending on the type of clean you're looking for but I have only used the standard 'clean' head so far.
The black color paired with the LED lights, charger, and soft feel of this toothbrush definitely set it apart from the other toothbrushes in our bathroom (and any other toothbrush I've ever used). The charger is amazing too! It comes with a heavy glass that can be used to charge the toothbrush but I preferred the small charger instead...it's great because it takes up very little space compared to other electric toothbrush chargers and can easily be cleaned (unlike other chargers).
This toothbrush was a bit on the pricey side but I think it's worth every penny! I'm looking forward to my next dentist checkup to see if they notice any improvements to my oral health.
- Reviewed in Canada on September 23, 2023Verified PurchaseBrought this 4.5yrs ago. It just quit on me. I called Phillips and after an over the phone question and answer session they deemed I could have a brand new one for free ! They sent it out to me with no charge. Great toothbrush. always reliable. not sure why it died after 4.5yrs but awesome customer service from Phillips !
- Reviewed in Canada on September 7, 2017Verified PurchaseI finally gave it a try from recommendations from my friends and dental hygienist. It's a great brush with multifunctionality. It took about 2 weeks to switch 100% from a traditional toothbrush. Battery lasts about 3 weeks and the charging station is pretty cool. The travel case could be better if it had a latch; the model I have is relying on a magnet.
The app is smart, GUI can be better but I think it needs more love but that may just be me being nit picky.
As this is a pretty hefty ticket item I would have switched earlier had I tried it in the past which is not very easy.
- Reviewed in Canada on May 22, 2019Verified PurchaseNow look, I'm totally with you. This seems expensive. No, it is expensive, not just for a toothbrush, but any personal grooming hardware. I promise I hummed and hawed for months. I was not let down. My teeth and mouth have never felt so clean, save for post dentist. I had the cheap version without the bells and whistles prior to the 9300. This experience is the difference between a regular manual and the entry level phillips. I cant imagine the 9700 version being that much better with a couple extra brush heads... This is a great buy at 200 dollars. Happy brushing!!!
- Reviewed in Canada on March 20, 2018Verified PurchaseHas a lot of settings so that you can deep clean or get a sensitive clean. Have been using it on the Gum Health and my teeth feel way cleaner after every brush compared to my old Oral B electric brush. I think the replacement heads will be a be more costly but so far well worth it.
- Reviewed in Canada on June 17, 2022Verified PurchaseI have this toothbrush for 2 years but don’t get me wrong, I have been having problems since the first few months. They had to replaced it 4 months in because it got loose the connector and started making weird noises. Then battery issues where doesn’t last at all, not it stopped even charging so I basically lost the toothbrush now. Very disappointed
- Reviewed in Canada on February 21, 2021Verified PurchaseI decided to switch to an electric tooth brush following a dentist appointment where I was told my gums weren't happy with my brushing pressure. This brush cleans my teeth 200x better without stressing my gums! Thr battery life is surprisingly long (survives a week long vacation). The application can be handy to make sure you go around evenly, but the brush tells you when to move nonetheless.
- Reviewed in Canada on August 21, 2018Verified PurchaseHad this brush for a few days now, my teeth have never felt cleaner! The app tells you if you're moving to fast, and if you're applying to much pressure. The brush is very nice, quieter than expected, and cleans very well! Would recommend to everyone!
