The Sweet Spot for Smart Features
The iO Series 7 represents a significant step up from the Series 5 and 6 because it introduces two features that genuinely enhance the brushing experience: an OLED display and AI-powered brushing recognition. While the Series 5 is our value pick, the Series 7 is where the iO lineup starts to feel truly premium.
The black-and-white OLED display replaces the basic LED indicators found on the Series 5 and 6. Instead of small light-up icons, you get a crisp screen that clearly shows your selected mode, a real-time timer countdown, battery level, and pressure feedback. When you finish a two-minute session, a smiley face animation appears. It is a small touch, but it transforms the brush from a tool into an engaging experience.
AI-Powered Brushing Recognition
The headline feature of the Series 7 is AI tracking. When connected to the Oral-B app, the toothbrush's motion sensors work with AI algorithms to detect which areas of your mouth you are brushing. The app displays a real-time map showing covered and missed zones, giving you immediate feedback on your technique.
In practice, this means you can open the app, start brushing, and watch as the diagram fills in. If you tend to neglect your lower right molars (a common habit), the AI tracking will highlight it. Over time, this feedback helps you develop more thorough habits. The Series 7's AI tracking is zone-based rather than the full 3D mapping available on the Series 9, but it is still a meaningful improvement over no tracking at all.
You do not have to use the app every time — the toothbrush works perfectly on its own with the built-in timer and pressure sensor. But the AI tracking is there when you want it, making it a valuable optional feature rather than a requirement.
Design and Build Quality
The Series 7 shares the sleek iO design language: a matte-finish handle with a comfortable grip, a single power button for mode cycling, and the prominent OLED display window on the front face. The handle is available in multiple colors depending on the retailer. Build quality is premium — the brush feels solid and well-engineered in the hand.
The included travel case is a hard-shell protector that fits the handle and a spare brush head. It is functional and well-made, offering good protection for travel. This is the same quality level as the Series 6 case.
Brushing Experience
The five cleaning modes on the Series 7 are identical to the Series 5 and 6: Daily Clean, Intense, Whiten, Sensitive, and Super Sensitive. The magnetic drive feels the same across all iO models — smooth, quiet, and powerful. What makes the Series 7 experience better is the OLED feedback. Seeing your mode name clearly displayed, watching the timer count down, and getting visual pressure warnings on the screen is more intuitive than reading LED indicators.
The pressure sensor integrates beautifully with the OLED. The display shows a colored ring that changes from green (ideal) to red (too hard) as you brush, giving you constant visual feedback. This is more effective than the simple LED light on cheaper models because it is harder to miss — the display is right in front of you as you look in the mirror.
