Sonic technology
The sonic sweeping motion whips toothpaste into plaque-fighting bubbles and drives them between your teeth and along the gumline. Your teeth will enjoy up to 62,000 gentle yet effective brush strokes at the same time. In just 2 minutes, you'll get the same effect as a month of manual brushing. Gentle sonic technology is suitable for use with braces, fillings, crowns and veneers. It also prevents cavities 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 towards better and more effective tooth brushing! It has built-in smart sensors to help you tell 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.
Tooth brushing 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 the app, the toothbrush will offer you feedback on your brushing and also tips for better cleaning. It guides you towards better brushing habits and lets you 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 press too hard while brushing
If you unknowingly apply too much pressure to your teeth and gums, you may not even notice, yet long-term application of too much pressure can cause a variety of health problems. The Philips Sonicare 9400 DiamondClean toothbrush is therefore equipped with a sensitive pressure sensor that can alert you to the wrong amount of pressure. If the pressure is not optimal, the toothbrush will begin to vibrate gently. 7 out of 10 people say that this feature 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 surface stain removal, Gum Health mode for gentle gum care, and Deep Clean+ mode for a refreshing deep clean. You can also choose from 1 of 3 intensity settings for your maximum comfort.
Position sensor tracks and improves coverage
Thanks to the Philips Sonicare 9400 DiamondClean toothbrush with 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 while you brush. Via the mobile app, you can easily see if you are giving all surfaces the care they need.
Brush head recognition and synchronisation 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 it and automatically suggest the cleaning mode that best suits the attached head. This helps to achieve even better results.
BrushSync brush head replacement reminder
The toothbrush head needs to be changed regularly to keep its performance effective over the long term. The Philips Sonicare 9400 DiamondClean features BrushSync technology, which tracks brush head wear based on the frequency and way you brush your teeth. When it's time to replace the head with a new one, the toothbrush alerts you with a beep and by lighting up an indicator on the handle.
Long battery life
The reliable Philips Sonicare 9400 DiamondClean toothbrush has a very long-life 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.
