Oral-B iO Series 9 vs Philips Sonicare ProtectiveClean 4100
Side-by-side comparison of features, pricing, ratings, and alternatives.
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.
The Philips Sonicare ProtectiveClean 4100 is an electric toothbrush engineered to deliver superior plaque removal while remaining gentle on your gums. Featuring advanced sonic technology, it drives fluid deep between your teeth and along the gumline for an exceptionally clean feel. Designed for everyday use, this toothbrush includes a built-in pressure sensor to protect teeth and gums from excess brushing pressure, along with a smart replacement reminder to ensure optimal brush head performance over time.
Around $299.99 MSRP.

Oral-B iO Series 9 is solid overall, though it's not perfect. On the plus side, genuinely useful real-time pressure feedback. That said, app features require a smartphone, which held us back from rating it higher.
