most used power toothbrush brand by dental professionals
Sonicare Prestige with SenseIQ technology is our most advanced power toothbrush. It enhances our proven sonic technology with intelligence, sensing and adapting to your needs for holistic care, so you always get it right. Removes up to 20 x more plaque.1
20 x more effective on plaque*, gentle on gums
Everyone cleans differently, so we designed this brush head with multi-angle bristles to keep plaque removal on course no matter your technique. Our All-in-One A3 brush head delivers our best cleaning and removes up to 20 x more plaque, 15 x healthier gums in six weeks and up to 100% more stain removal in less than two days versus a manual toothbrush.
SenseIQ Technology for your personalised experience
SenseIQ Technology helps balance your brushing style and senses your pressure, motion and coverage up to 100 times per second while you brush. If you apply too much pressure, the toothbrush will step in and automatically adjust the intensity level, helping to protect your teeth and gums.
Sonicare Fluid Action
Philips Sonicare toothbrushes clean gently yet effectively and care for your teeth and gums with 62,000 bristle movements per minute. Sonicare Fluid Action supports the bristles to clean by driving fluid deep between teeth and along the gumline.
Help protect your gums with our pressure sensor
This Sonicare electric toothbrush has a light ring at its base that gently lets you know if you're overdoing the pressure. Simply ease off when it lights up to help your gums stay protected.
Choose your ideal cleaning experience
Enhance your oral care routine with 15 brushing settings. Whether you're looking for a deep clean or a specific focus, you can have it with this electric toothbrush. Select from five modes—Clean, White+, Gum Health, Deep Clean and Sensitive—and adjust to one of three intensity levels for a personalised clean. Simply open the app, select your preferences and let your toothbrush do the rest.
Personalised guidance and real-time feedback
Achieve your oral health goals with your Sonicare toothbrush and app. The two pair seamlessly to provide real-time coaching, personalised guidance and tailored insights to improve your brushing routine. Track your progress, refine your technique and receive continuous feedback to make the most out of each brushing session. Together, you are unstoppable. Meanwhile, auto-syncing keeps brushing data up to date in the app, even when you don't brush with the app by your side.

HX9992 diamond clean sonic brush totally awesome
The philips HX9992 diamond clean toothbrush is awesome, although a bit expensive , however i waited for a black friday deal and it was still expensive but far cheaper than before. But what can I say it is great and that good i purchased another for my partner and she couldn't believe how well it cleaned her teeth. And the travel case is great too. Product support is awesome, as mine after about a year started to be a bit noisy with a common fault in which the screw holding the metal head plug worked loose. This was quickly swapped out by their support which was awesome as the brush was expensive in the first place. Overall wow it great and worth it.

Best toothbrush you can buy!
This is the best toothbrush I have used. It does everything it says on the box. My teeth are cleaner and gums feel better. A lot better than my Oral b IO toothbrush. Worth the extra expense!
