oral b smart series

iO series brushes offer a range of smart/cleaning modes, typically from 3 up to 7 different modes depending on the model.

Most iO packages include at least one replacement brush head plus a charger base, and many also include a travel case; some packages include multiple heads (for example, four).

iO brushes include a visible/smart pressure sensor that indicates optimal brushing pressure and warns when you brush too hard to help protect gums.

iO models use timers, interactive color displays, and AI/3D teeth tracking or recognition together with app coaching to map coverage and guide brushing across mouth zones.

iO brushes include a built‑in 2‑minute timer with quadrant pacing that pulses every 30 seconds to guide even coverage of all mouth areas.

The iO series uses magnetic iO technology and gentle micro‑vibrations combined with a dentist‑inspired round brush head and a magnetic drive system to power the bristle tips.

Reviews commonly praise the app and tracking/pressure‑monitoring features and describe the brushes as easy to use once adjusted to the coaching; reviewers also note helpful timers and pressure alerts.
