Oral-B iO Series 9
Best Overall — AI Pressure Sensing, Full Mouth Coverage Map
The Oral-B iO Series 9 is the most technologically advanced consumer toothbrush available. Its round oscillating head combined with micro-vibration linear magnetic drive system produces the highest plaque removal efficiency in our testing — outperforming all sonic competitors in the critical gumline zone. The AI-powered pressure sensor stops the brush and alerts you before gum recession-causing over-pressure occurs. The companion app maps your entire mouth in real-time, showing exactly which areas you've missed. Seven brushing modes cover all conditions from sensitive gums to whitening to periodontal care.
