Product details

The most advanced technology from Oral-B removes 100% more plaque in just one week and even 300% more along the gum line compared to a manual toothbrush - well tested by Stiftung Warentest.

For whiter teeth from day one, the dentist-inspired round iO brush head removes surface stains.

100% brushing coverage thanks to our most innovative AI position detection with 3D tracking of brushing movements in 16 zones.

Longer good oral health - 8 out of 10 people were able to brush better after just one week thanks to personalized iO brushing guidance.

The smart toothbrush from Oral-B features an interactive color display for selecting the 7 brushing programs, tracking brushing time, reminding you to replace the brush head, and showing battery status.

Enjoy relaxed brushing at home and on the go with the quick charging station and travel case - with a battery level indicator on the display.

Protects the gums with the iO pressure control - lights up red with too much pressure, white with too little pressure, and shows green light for the perfect pressure for effective and gentle cleaning.

Easily switch to Oral-B and test the electric toothbrush risk-free with a 30-day money-back guarantee. Terms and conditions apply on the Oral-B website.

Instead of a classic vibration motor, the Oral-B brand relies on an innovative magnetic drive for the toothbrush. The difference: the vibrations are much gentler than those of conventional competitor models. However, the iO-Series 9 has much more to offer: For example, the smart brush recognises which areas have already been brushed and shows this on the built-in colour display...

Rank 3 out of 11Stiftung WarentestElektrische Zahnbürsten ab 2021 - AkkuzahnbürstenReleaseDecember 2021

Lavishly equipped. The high-priced round-head brush cleans the teeth well and uses oscillating-rotating and vibrating movements. If you press down too hard while brushing, a light signal warns you. Seven cleaning settings and a charging travel case are also part of the equipment. The brush can be connected via Bluetooth to the Oral-B app, which is designed to support tooth brushing.
