About the ProtectiveClean 5100
The 5100 adds a gum-care mode and three intensity settings to the ProtectiveClean formula, with the same pressure sensor as the rest of the range. It sits in the middle of the three ProtectiveClean tiers and is the one most people step up to from the 4300.
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.
Never think about it again
Set your replacements to arrive every two, four or six months and save 15% on every order. Skip, pause or cancel whenever you like.
