IO is Oral-B's advanced cleaning technology that combines a unique round brush head with gentle micro-vibrations. An innovative linear magnetic drive focuses energy precisely where it's needed most - at the tips of the bristles. Experience a refreshing feeling of cleanliness and 100% healthier gums in just one week. Enjoy surprisingly gentle cleaning and quiet operation to achieve the best Oral-B results from the start. It removes up to 100% more plaque compared to a regular toothbrush, resulting in healthier gums in one week.

Inspired by dentists, the unique round brush head effectively cleans using micro-vibrations as well as rotating and oscillating movements. The cross-shaped bristles are arranged at a 16° angle to wrap around each tooth, ensuring maximum cleaning and effective plaque removal along the gum line. The AI recognizes your brushing style and provides guidance in the Oral-B app to ensure no areas remain unclean. The smart pressure sensor lights up red when you brush too hard and green when you brush correctly. An interactive black-and-white display informs you about five cleaning modes, charging times, and more. The magnetic charger is stable and offers a quick charge in about three hours.
