The Philips Sonicare DiamondClean 9000 is an innovative sonic toothbrush that removes up to 10 times more plaque than a manual toothbrush for naturally white teeth. It is suitable for braces, fillings, crowns and veneers, so you can brush your teeth without worry.
There are 4 cleaning modes: Clean mode for daily cleaning, White+ mode for removing discolouration, Gum Health mode for gentle but effective cleaning of the gums and Deep Clean+ mode for a refreshing, thorough clean. There are 3 intensity levels available.
The integrated Philips Sonicare pressure sensor informs you when you press too hard – the handpiece pulses slightly and reminds you to brush gently. Advanced sonic technology provides gentle yet effective cleaning by flushing liquid into the interdental spaces and along the gum line and providing a cleaning performance of 62,000 bristle movements per minute.
The innovative BrushSync technology informs you when it’s time to change the brush head. To help you get used to the Sonicare, EasyStart adjusts the power level during the first 14 applications. Improve your brushing technique with the 4-quadrant timer. In addition, you can reach the recommended cleaning time of 2 minutes with the 2-minute timer.
The Philips Sonicare DiamondClean 9000 is perfect as a toothbrush on the go thanks to the slim and elegant travel case. With regular use, the battery lasts up to two weeks on a single charge (based on two cleaning cycles of two minutes per day in standard mode).
