Oral-B is a Procter and Gamble oral care brand. Its iO electric toothbrushes combine powered cleaning, pressure feedback and app coaching. Advanced models track brushing coverage.

How it works
A magnetic drive moves the round brush head while a pressure sensor detects force against the teeth. Coloured lights show when pressure is high, low or appropriate. Motion sensing software estimates which areas of the mouth have been covered. Bluetooth sends this information to the Oral-B app for guidance and tracking.

Key considerations
Tracking accuracy depends on brushing technique, phone position and the toothbrush model. The app may misidentify areas, so users need a complete routine and regular brush head replacement. Smart coaching supports oral hygiene but cannot detect cavities, gum disease or other dental problems. Professional dental checks remain necessary.
