The DiamondClean 9000 HX9911/27 offers personalized brushing thanks to its smart app. Its 4 modes and 3 intensities effectively remove plaque while protecting your gums. For a dazzling smile, day after day.

Features

Removes up to 100% more stains in 3 days

A thorough clean requires a special approach. This C3 brush head has dense, stiff bristles in the center in a pentagonal shape to whiten and polish your teeth. This allows you to remove up to 100% more stains in three days. It also removes up to 10 times more plaque than a manual toothbrush.

Sonicare fluid flow

Philips Sonicare toothbrushes gently and efficiently clean and care for your teeth and gums with up to 62,000 bristle movements per minute. Sonicare fluid flow supports the bristles in cleaning by flushing fluid deep into the interdental spaces and along the gum line.

Protect your gums with our pressure sensor

It's easy to apply too much pressure when brushing your teeth. That's why this Philips Sonicare toothbrush has a smart optical sensor that detects excessive pressure. If you apply too much pressure while brushing, gentle vibrations will remind you to reduce the pressure to protect your gums.

Choose your ideal brushing experience

Enhance your dental care routine with 12 brushing settings. Whether you're looking for a thorough clean or a specific focus, this electric toothbrush is right for you. Choose from five brushing programs—Clean, White+, Gum Health, and Deep Clean—and set them to one of three intensity levels for a personalized clean.

Brushing insights at the touch of a button

Achieve all your oral care goals with the Sonicare toothbrush and app. Both connect seamlessly to provide you with brushing guidance, tips and tricks, and personalized content. You'll be unstoppable.

Carefully designed for dental care

From its sleek design to its simple charging glass, this electric toothbrush has been developed with attention to detail by our dedicated designers and engineers. What's more, the travel charging case protects your toothbrush wherever you go and keeps it charged.

Continue brushing with optimal performance thanks to the brush head replacement reminder

Did you know that brush heads lose their effectiveness after three months? Dental professionals recommend replacing your brush head regularly. That's why Philips Sonicare toothbrushes feature a brush head replacement reminder. It tracks how often and how hard you brush, then reminds you to replace your brush head when the time comes.

14 days of regular cleaning

A full charge lasts up to 14 days of regular brushing. You'll enjoy a whole new level of comfort in your daily brushing routine.
