What is Oral-B iO Series 9?
The Oral-B iO Series 9 pairs a magnetic, micro-vibrating brush head with linear magnetic drive technology for a smoother, gentler brushing motion compared to traditional oscillating-rotating brushes, while still delivering thorough plaque removal. A color-coded smart pressure sensor lights up green, yellow, or red on the handle to indicate ideal, acceptable, or excessive brushing pressure, helping prevent gum damage from brushing too hard. The companion app uses the phone camera during brushing to provide an AI-powered 3D mouth map showing which areas were missed or need more attention, turning brushing into a more guided, data-driven routine.
