Frequently Asked Questions
What is the difference between the Oral-B iO9 and iO3?
The iO9 adds AI Position Detection, a 3-zone pressure sensor (not just over-pressure warning), an interactive display, 7 cleaning modes (vs 3 on the iO3), and a travel case. The core iO brush head technology is shared across the range.
Do I need the app to use the Oral-B iO9?
No — the iO9 works fully as a standalone electric toothbrush without the app. The AI position detection and brushing guidance features are app-dependent, but all 7 cleaning modes and the timer function work independently.
Are Oral-B iO brush heads compatible with the iO9?
Yes — all Oral-B iO Series brush heads (Ultimate Clean, Gentle Care, Whitening, etc.) are compatible with the iO9 handle. Older Oral-B EB-series heads (for Pro and Vitality models) do not fit the iO range.
How often should I replace the brush head?
Oral-B recommends replacing the iO brush head every 3 months, or when the blue indicator bristles fade to white. Using a worn head significantly reduces cleaning effectiveness.
