iO Series 9 Electric Toothbrush

The Oral-B iO Series 9 uses a linear magnetic drive for micro-vibrations that deliver a dentist-clean feeling at home. What makes it BIFL is the user-replaceable battery, a rarity in electric toothbrushes that typically become e-waste when the battery dies. The 3D tracking and AI-powered app ensure every tooth gets proper attention.
