iO Series 9 Electric Toothbrush
The iO Series 9 represents the pinnacle of oscillating-rotating technology, which has been clinically proven to remove more plaque than manual and some sonic competitors. Its frictionless magnetic drive system concentrates energy into the bristle tips, and the smart pressure sensor is the most accurate on the market for protecting gum tissue.
Ingredients & Purity
Bristles are made of high-quality, rounded end-polishing synthetic filaments to prevent micro-lesions on enamel. The handle uses medical-grade plastics and a high-resolution color display.
Scientific Evidence
Carries the ADA Seal of Acceptance. Numerous independent clinical trials show oscillating-rotating brushes provide a statistically significant reduction in plaque and gingivitis compared to manual brushing.
Brand Transparency
P&G provides comprehensive technical specifications, clinical trial data summaries, and clear manufacturing origins for their German-engineered iO line.
Value Assessment
At $250, it is a premium investment. However, the reduction in potential dental bills for fillings and deep cleanings justifies the cost for users with high plaque buildup.
Why Not Alternatives?
Unlike the Quip or standard vibrating brushes, the Oral-B iO uses actual mechanical oscillation. It outperforms the cheaper Oral-B Pro series by being significantly quieter and having a more sophisticated pressure sensor that indicates not just 'too hard' but also 'just right' pressure.
