The Gum Health Benefit of the iO Pressure Sensor Explained
The iO Pressure Sensor signals whether pressure is too hard, too soft or just right, delivering immediate feedback via the light ring. Direct feedback prevents aggressive strokes and preserves gum tissue over time.
Immediate corrections from the sensor produce gentler technique and healthier gum margins after regular use. The handle sits in the palm like a bar of soap, offering a secure grip for every cleaning session.
Oral-B App Guided Brushing: The Professional's Verdict
App connectivity records performance reports, journeys and goals to track progress across weeks, turning each session into measurable improvement. A connected routine encourages consistency and clearer focus on missed zones.
If you have rushed two-minute sessions before, the app keeps timing and technique honest and builds better habits over time. Guided feedback and progress charts deliver visible improvement in daily care.
