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.

Questions about Smart Series compatibility

Will these fit my Smart Series?

Yes — the Smart Series uses Oral-B's standard round fitting, which our heads are made for. Check the model name or D-code on the base of your handle against the list above. The one exception across the Oral-B range is the iO series, which takes only iO heads.

Will these fit my Oral-B iO?

No, and we would rather say so before you order. The iO range uses a magnetic drive that only iO heads connect to, so no standard round head fits it — ours included. If your handle is a Pro, Vitality, Smart or Genius, you are in the right place.

What are booheads Oral-B compatible heads made of?

A wheat straw body blended with plant-based PLA, and castor-oil plant bristles. No virgin plastic handle, and nothing exotic — just the two materials.

Will my pressure sensor still work?

Yes. The sensor lives in the handle and reads how hard the motor is working, not what head is fitted, so it behaves exactly as it does now. The same goes for the timer, the modes and the app if your handle has one.

How often should I replace my head?

Every three months, or sooner if the bristles start to splay. Worn bristles clean less well and are harder on your gums.

How many heads come in a pack?

Four, which is about a year of brushing if you change every three months.

Can I subscribe?

Yes. Choose a delivery frequency and save 15% on every order. Skip, pause or cancel whenever you like.

Are these official Oral-B heads?

No. booheads is an independent brand with no affiliation to Oral-B or Procter & Gamble. Our heads are designed to fit compatible Oral-B handles that use the standard round fitting, and we name the models so you can check yours before you buy.
