Complete care for your teeth and gums
Personalised advice for better brushing
Intelligent brush head equipped with sensors
Sonic technology
The sonic sweeping motion whips toothpaste into plaque-fighting bubbles, driving them between teeth and along the gumline. At the same time, your teeth will enjoy up to 62,000 gentle, yet effective brush head movements. In just 2 minutes, you'll get the same effect as a month of manual brushing. This gentle sonic technology is suitable for use with braces, fillings, crowns and veneers. What's more, it prevents tooth decay and improves gum health.
Personalised advice
Are you sure you're brushing your teeth correctly and not missing any spots? The Philips Sonicare 9400 DiamondClean sonic toothbrush will reliably guide you to better and more effective brushing! It has built-in smart sensors to help you know if you're applying too much pressure, and a position sensor reveals which areas need more care. Based on the data collected during brushing, the toothbrush provides you with valuable advice specific to you and your oral health via a smart mobile app.
A toothbrushing app
Get the most out of your Philips Sonicare 9400 DiamondClean toothbrush! The smart Philips Sonicare mobile app is free to download for iOS and Android. Through it, the toothbrush will offer you feedback on your brushing and also tips for better cleaning. This guides you towards better brushing habits and allows you to track your own progress.
Removes up to 10× more plaque than a manual toothbrush
Compared to thorough traditional brushing with a manual toothbrush, the Philips Sonicare 9400 DiamondClean can remove up to 10× more plaque. The package includes the precise universal A3 Premium 'all-in-one' head and the G3 Premium Gum Care brush head for gentle care of sensitive gums.
Pressure sensor alerts you if you're brushing too hard
You might not even notice if you're unconsciously applying too much pressure on your teeth and gums, yet long-term application of excessive pressure can cause a whole range of health problems. That's why the Philips Sonicare 9400 DiamondClean toothbrush is equipped with a sensitive pressure sensor that can alert you to incorrect pressure. If the pressure isn't optimal, the toothbrush will start to vibrate gently. 7 out of 10 people report that this feature has helped them brush their teeth better.
4 modes and 3 intensity settings
The innovative Philips Sonicare 9400 DiamondClean toothbrush cleans your teeth just the way you need and find most comfortable. You can choose from Clean mode for thorough daily cleaning, White+ mode for effective removal of surface stains, Gum Health mode for gentle gum care, and Deep Clean+ mode for a refreshing deep clean. You can also select 1 of 3 intensity settings for your maximum comfort.
Position sensor tracks and improves your coverage
Thanks to the Philips Sonicare 9400 DiamondClean toothbrush with its smart mobile app, you won't miss a single spot in your mouth. The device has a built-in position sensor and records every movement in your mouth during brushing. Through the mobile app, you can easily see if you are giving all surfaces the necessary care.
Brush head recognition and pairing with the optimal mode
The body of the Philips Sonicare 9400 DiamondClean toothbrush can synchronise with the brush head thanks to a built-in chip. It can recognise the head and automatically suggest the cleaning mode best suited to it. This helps to achieve even better results.
BrushSync brush head replacement indicator
Toothbrush heads need to be changed regularly to keep their performance effective over the long term. The Philips Sonicare 9400 DiamondClean is equipped with BrushSync technology, which can track the wear of the brush head based on the frequency and manner of your brushing. When it's time to replace the head with a new one, the toothbrush will alert you with a beep and by illuminating an indicator light on the handle.
Long battery life
The reliable Philips Sonicare 9400 DiamondClean toothbrush has a very long-lasting battery. One full charge provides up to two weeks of regular use.
What can you expect from this toothbrush?
Immediate effect: Plaque removal. A sonic electric toothbrush can remove up to 10× more plaque than a regular manual toothbrush. In one minute, it performs up to 62,000 strokes in the mouth, while a manual toothbrush performs only 300 to 400. Within the first week: visibly whiter teeth. Brushing your teeth twice a day with the correct technique, combined with the use of interdental aids, will lighten stains from coffee, wine, tea and smoking. Long-term: decay prevention and healthy gums.
