Oral-B iO Series 9 Electric Toothbrush
Oral-B's flagship — AI-powered position tracking, 7 cleaning modes, and an interactive display make this the most advanced rotating brush money can buy.
Our Review
The iO Series 9 is the top of Oral-B's lineup and it shows. The interactive color display lets you select modes, track brushing time, and see battery level at a glance. The AI-powered Oral-B app tracks exactly where you brush across all 3 tooth surfaces in real-time, ensuring you never miss a spot. With 7 cleaning modes, a 3-zone smart pressure sensor (red/white/green), magnetic charging, and a premium travel case, this is the brush for people who want the absolute best oscillating-rotating experience. The price is steep, but the technology is unmatched in this category.
