These refill heads push onto any Oral-B iO handle and bring back the round head shape, so bristles cup each tooth rather than sweeping flat across it. The layout is dense and set up for cleaning around sensitive teeth and gum lines, with an outer ring of finer filaments cushioning the edge where the head meets your gums.
There are eight heads in the pack, and the coloured bristles fade to white as they wear, so there is no guessing when one is spent. Pull the used head off, click a fresh one on, and the bristles are back to full shape against every tooth.
How to Use:
- Pull the used brush head off the Oral-B iO handle.
- Push a fresh head on until it clicks into place.
- Swap to a new head every three months, or sooner once the bristles have faded to white.
What's Included:
- 8 x Oral-B iO Clean & Gum Protect brush heads in White
