Whitens teeth in just one week
Click on the W2 Optimal White brush head to remove surface stains and reveal a whiter smile. With its densely packed central stain-removal bristles, it's clinically proven to whiten teeth in just one week.
Up to 7x more plaque removal than a manual toothbrush
Densely-packed, high-quality bristles remove up to 7x more plaque than a manual toothbrush.
Lets you know if you're pressing too hard
You might not notice if you're brushing too hard, but your ExpertClean will. If you need to ease up, this intelligent toothbrush will make a pulsing sound. It's a heads-up to let your brush head do the work. 7 out of 10 people found this feature helped them become a better brusher.
BrushSync automatically selects the best mode for you
Smart brush heads ensure that you're using the right mode and intensity for the best possible clean. For example, if you're using the G3 Premium Gum Care brush head, your Series 7900's BrushSync technology will automatically sync your brush head with the Gum Health mode to help give your gums a clean bill of health.
Always know when to replace your brush heads
All brush heads wear out over time, so you'll want to keep an eye on yours to make sure you're still getting a great clean. Our BrushSync technology tracks how long you've been using your brush head for and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep remind you when it's time to replace it.
Personalised brushing experience
Series 7900 comes with Clean, White+, Gum Health and Deep Clean+ to take care of your brushing needs. Clean mode is for exceptional everyday cleaning, White+ is for removing stains, Gum Health provides a gentle yet effective clean for gums and Deep Clean+ gives you an invigorating deep clean. Three intensities allow you to choose between a higher setting to boost your clean and a lower one for more sensitive mouths.
Lets you know if you're pressing too hard
You might not notice if you're brushing too hard, but your Series 7900 will. If you need to ease off, the toothbrush will make a pulsing sound. It's a reminder to let your brush head do the work. 7 out of 10 people found that this feature helped them become a better brusher.
Guidance to start and keep up healthy habits
Series 7900 gives you the guidance that you need to improve and maintain healthy brushing habits in between dentist check-ups. Built-in smart sensors let you know when you're using too much pressure, and by connecting your brushing experience to the Sonicare app, a personalised Progress Report helps you stay on track and see how much you've improved over time.
Simple to charge and style to boot
Your Series 7900 will last for up to two weeks on a single charge with regular use.
USB charging travel case charges your handle anywhere
