About the Smart Series
The Smart range added Bluetooth and app coaching on top of Oral-B's standard round-head platform. Worth knowing that the app's replacement reminder is a timer you reset yourself rather than something that reads the head, so it keeps working exactly the same whichever head you fit.
Why people switch to booheads
Same fit, better head. Here's what you actually get.
Plant-based bristles
Castor-oil based bristles instead of standard nylon — soft on gums, firm enough to clean properly.
A bamboo body
The part you hold is bamboo, not plastic. It's the reason these feel different in the hand.
Clicks straight on
No adapter, no fiddling. It seats on your existing handle exactly the way the original does.
Four to a pack
Change every three months and one pack covers your year. Subscribe and they simply turn up.
