Philips Sonicare 9900 DiamondClean Prestige HX9992/11

Sense IQ Technology

Meet the first Philips Sonicare brush with SenseIQ technology. You can relax while you brush as SenseIQ technology senses the force of pressure, your motion, area coverage and more up to 100 times per second. Real-time data-evaluation allows the Sonicare brush to adapt cleaning intensity. So, if you are putting too much pressure on your teeth and gums, the brush takes immediate action. Treat yourself to easy and professional care with better brushing over time. With SenseIQ technology, you can rely on the right tooth cleaning technique for your needs and achieve a unique personalised cleaning experience.

Philips Sonicare Technology

Remove unwanted dental plaque with sonic technology. Sonic movements create a wave that gently removes plaque from interdental spaces and along your gum line. While you brush, up to 62,000 dynamic and fluid bristle movements get into hard-to-reach places to leave your mouth feeling exceptionally fresh and clean. Gentle sonic technology is suitable for cleaning around braces, fillings, crowns and veneers. Prevent tooth decay and improve gum health with Sonicare technology.

Senses and adapts

The Philips Sonicare 9900 DiamondClean Prestige uses sensors and adaptive SenseIQ technology to synchronise and adjust your tooth-cleaning technique. It evaluates and recommends the best possible way to care for your teeth and gums. The pressure sensor alerts you if you are brushing too hard or start scrubbing, then adjusts the intensity level to suit your needs. A further sensor monitors and reports if you forget to clean an area of your mouth. The sensors scan up to 100 times per second and monitor the time you spend cleaning.

Longer bristles at the edges of the brush head clean deep around gums that are up to 15 times healthier in just two weeks***. Discover a whole new feeling of clean teeth and healthy gums.

Pressure sensor

You might not notice if you put too much pressure on your teeth or if you start scrubbing, but the 9900 DiamondClean Prestige brush will. If you brush too hard, the light ring on the end of the handle turns purple and the body of the brush vibrates to gently remind you to ease the pressure.

Stop scrubbing

If the brush detects a change in cleaning technique, such as when you "scrub" your teeth, the light ring turns amber, and the body vibrates (you can choose to turn this feature off using the application). The brush gives you instant feedback during cleaning to help you improve your technique.

Smart mobile application

The Philips Sonicare mobile app boasts artificial intelligence to provide an unbeatable cleaning experience. Take full advantage of the app and use it for real-time cleaning with personalised instructions based on data collected from your teeth-brushing style. The application informs you about pressure, movement, coverage of cleaned teeth and gums, duration and frequency of cleaning.

Cleaning feedback

Has your dentist or dental hygienist pointed out any problem areas in your mouth? You can use the app to highlight them on the 3D mouth map, which communicates with the 9900 DiamondClean Prestige to remind you to take extra care in the area. Philips Sonicare notifies you when your teeth are completely clean and advises you on how to brush your teeth better and more thoroughly. If you miss an area when brushing your teeth, the TouchUp function will show you where to return to make sure you always achieve completely clean teeth. The app stores cleaning reports and you can view progress reports by day, week, month and even year. The data in the app automatically synchronises and updates, even if you do not have your mobile phone and app during cleaning.

Personalised cleaning

The 9900 DiamondClean Prestige handle has just one button—to turn the brush on or off (it also switches off automatically after two minutes of cleaning). You don't have to think about which cleaning mode is the best for you, which will remove the most stains, get rid of the most plaque, or be the most gentle to your gums, as the 9900 DiamondClean Prestige does everything for you. The sonic toothbrush with SenseIQ technology captures your every move and chooses the most suitable mode based on your needs. The 9900 DiamondClean Prestige automatically selects from five cleaning modes—Clean and DeepClean focus on removing plaque, White+ removes stains, GumHealth does exactly what it says on the tin while Sensitive cleans your teeth gently.

Useful timers

SmarTimer monitors the recommended minimum cleaning time of two minutes and notifies you when this time has elapsed. The BrushPacer lets you know to spend the right amount of cleansing in each of the four quadrants of your mouth. As a result, teeth cleaning is maximally effective and correctly timed.

BrushSync Technology

As the brush head wears, it's plaque removal efficiency gradually decreases. Thanks to the intelligent BrushSync technology, you will never lose track of when to replace the head. The sensors in the toothbrush monitor how long and how hard you have been brushing your teeth and alert you when it's time to replace the head. You can also monitor the life of brush heads with Philips Sonicare. For best results, be sure to replace the head every three months.

Practical charging

Stylish charging is provided by an elegant hockey puck-shaped charging base, which takes up a minimum of space and serves as a design feature in any modern bathroom. One full charge provides you with up to two weeks of use****. A low battery indicator light on the brush body provides a timely reminder when your battery is running low.

Stylish storage and charging

If the brush runs out of power during travel, you can use the stylish compact travel case as a charger. Insert the brush into the USB charging case and plug it into your laptop or an electrical outlet. The simple design of the case is made of vegan leather and provides a secure fit.
