Philips Sonicare DiamondClean Smart 9000 HX9917/89

With the Philips Sonicare DiamondClean Smart 9000 HX9917/88, you're sure of good oral hygiene. You can choose from 4 different brushing modes, like the mode for whiter teeth or for sensitive teeth. You can also choose from 3 intensities, so you adjust the brushing movements to your teeth. Not sure what to choose? Thanks to the microchip in the brush attachment, the toothbrush can also choose the best settings for you. The accompanying smartphone app will coach you when you brush. This way, you see when you skip a spot, or if you press too hard, or if you need to brush some problem areas better. You'll also see when you need to replace your brush attachments. It's possible to charge the toothbrush in the travel pouch or with the charging glass.
