How we chose the best Oral-B iO toothbrushes
The best Oral-B iO toothbrush depends on which features you'll use each day, from a pressure sensor to live coaching across 6 brushing zones. We compared the modes, displays, sensors, app features and included travel items.
Our score weighs specs and features against what you're shopping for. A higher score reflects a closer fit for buyers seeking more brushing guidance and settings, while simpler models suit straightforward routines.
We considered the iO9's charger coaching separately from app tracking, since charger and phone feedback can suit different routines. We also noted what comes with each brush, including the number of brush heads and whether a travel case is included.
