The Sonicare app shows whether the cleaning was thorough. With the all-in-one premium brush head, the bristles achieve up to four times more surface contact. The four modes and three intensity levels cover the high care requirements of teeth.
Experience the deepest clean with the Philips Sonicare DiamondClean Smart Series 9400. The All-in-OnePremium brush head adapts perfectly to the teeth and removes up to 20 times more plaque from hard-to-reach areas compared to a manual toothbrush. The three intensity levels and four cleaning programmes - "Clean", "White+", "Deep Clean+" and "Gum Health" - cover all dental care needs. The Philips Sonicare app shows how thoroughly you are brushing and provides personalised tips, such as the TouchUp function, which helps to brush over missed areas. The Smart Brush Head Detection automatically reminds you to change the brush head based on usage time and pressure. The pressure sensor warns you as soon as you brush too hard, and seven out of ten people improved their brushing behaviour thanks to this function. An integrated scrub sensor ensures that no harmful movements are made, improving the technique. Optimise your oral care with Philips Sonicare DiamondClean Smart and the latest technology.
Advanced sonic toothbrush for improved oral health: up to 20 times more plaque removal compared to a manual toothbrush, up to 15 times healthier gums and up to 100 per cent less stains.

Real-time feedback: The light ring at the end of your handle flashes when too much pressure is applied and the vibration of your handpiece decreases. This keeps your teeth and gums protected.
