Product details

The best Philips Sonicare performance for white teeth with the most stylish electric Sonicare sonic toothbrush. Switch to the Philips Sonicare toothbrush.
With the C3 Premium Plaque Defense brush head, you know you're getting the best possible cleaning. The soft, flexible bristles adapt to the shape of your teeth, providing 4x more surface contact and up to 10x more plaque removal in hard-to-reach areas. With the Premium Plaque Defense brush head, you brush more thoroughly than ever before. Gentle, flexible sides and bristles adapt perfectly to the shape of your teeth, offer 4x more surface contact and clean even hard-to-reach areas. The DiamondClean 9000 gives you the guidance you need to develop and maintain a healthy brushing habit between dental checkups. Integrated intelligent sensors inform you when you apply too much pressure. The DiamondClean 9000 has the Clean, White+, Gum Health and Deep Clean+ cleaning programs to meet your dental care needs: Clean brushing program for exceptional daily cleaning, White+ brushing program to remove stains, Gum Health brushing program for gentle cleaning along the gumline and the Deep Clean+ brushing program for invigorating thorough cleaning. The three intensity levels allow you to choose between a higher intensity for even more thorough cleaning or lower intensity for sensitive teeth. The intelligent brush heads ensure that you use the right brushing program and intensity level for the best possible cleaning. For example, suppose you use the W3 Premium White brush head. The BrushSync technology on your DiamondClean 9000 automatically synchronizes your brush head with the White+ mode for whiter teeth. You may not notice if you clean too hard, but your DiamondClean 9000 will. If you apply too much pressure, the toothbrush handle will vibrate gently. This reminds you to brush softer and let your brush head do the work. 7 out of 10 people used this function for better cleaning. All brush heads wear out over time, so you should always make sure that yours continues to clean perfectly. BrushSync technology remembers how long you've been using your brush head and how hard you clean. The BrushSync reminder function on the handpiece and a short beep alert you when it's time to replace the brush head. Your DiamondClean 9000 will last up to two weeks if used regularly with a single charge.

With charging glass. The rather expensive sonic toothbrush cleans the teeth well. If too much pressure is applied to the teeth and gums, the visual pressure control warns you. Four different cleaning settings, each with three different intensity levels, can be selected. In addition to a conventional charging station, a charging glass and a travel case are also supplied...

The model "IO Series 7N" from Oral-B, at 215 francs one of the most expensive devices tested, scored best. It achieved the second-best score for the main criterion, rounding off the bristles. The device was also convincing in the other criteria. Also good: more than 100 brushing operations can be performed with one battery charge...
