Description

Product Description The Philips Sonicare DiamondClean Smart 9400 electric toothbrush provides complete and efficient oral care, removing up to 20 x more plaque than a manual toothbrush and providing up to 15 x healthier gums². It's safe to use with braces, fillings, crowns and veneers. There are 4 brushing modes: Clean mode for daily cleaning, White+ for stain removal, Gum Health for gentle but effective cleaning of the gums and Deep Clean+ for a refreshing, thorough clean. There are also 3 intensity levels to choose from. The built-in Philips Sonicare light ring pressure sensor lets you know if you're pressing too hard. The Advanced Sonic Technology provides gentle yet effective cleaning, pulsing fluid between teeth and along the gumline with a cleaning power of 62,000 bristle movements per minute. The innovative BrushSync™ technology will let you know when it's time to change your brush head. Improve your brushing technique with QuadPacer and reach your recommended brushing time of 2 minutes with SmarTimer. The Philips Sonicare DiamondClean Smart 9400 works perfectly as a travel toothbrush thanks to the premium travel case with an integrated USB. You can also top up the power at home with the iconic charging glass. With regular use, the battery will last up to two weeks on a single charge (based on two periods of two-minute brushings per day on standard mode). ¹ vs. a manual toothbrush ² in Clean mode vs. a manual toothbrush ³ based on a study of over 2600 dental professionals (dentists and hygienists) conducted in the United States, Canada, Japan, China, Korea, Thailand, Germany, the United Kingdom, Switzerland, France, Belgium, Austria, Italy, Spain, Sweden in 2022-2023 ⁴ after 3 days of use in White+ Mode vs a manual toothbrush using a leading whitening toothpaste.
