💡 Shared High-End Features of iO Series 7 and 9

✅ Revolutionary iO Technology

Both models use Oral-B’s iO magnetic drive, combining oscillating-rotating motion with gentle micro-vibrations. This tech delivers an ultra-smooth brushing experience that’s clinically proven to remove more plaque and improve gum health.

✅ AI-Driven App with Bluetooth Connectivity

We can synchronize both brushes with the Oral-B app, which uses artificial intelligence to track brushing habits and offer personalized coaching. The app highlights missed areas and provides real-time visual feedback.

✅ Smart Pressure Sensor

Both models include a 360° smart pressure sensor that glows red when brushing too hard, green when brushing just right, and white when there’s no pressure. This helps protect enamel and gums from aggressive brushing.

✅ Sleek and Ergonomic Design

Each toothbrush features a sleek, modern design with a non-slip handle and minimalist buttons. The magnetic charger delivers a full charge in ~3 hours.
