Real floss. Held for you.

It holds a taut span of real floss between two prongs, and the handle supplies the motion while you guide it. One hand, no wrapping, nothing to thread.

What we mean by Fifth Surface

Every tooth has five surfaces. Three get brushed.

Brushing is built for the three exposed sides: front, back, and the chewing surface. The other two face the neighbouring teeth, where bristles cannot enter the tight contact.

That overlooked territory is the Fifth Surface. It is what we named the company after, and what the product exists to reach.

What people are saying

Based on verified reviews

The clean feeling surprised me

I brush twice a day, so I assumed my mouth already felt clean. After my first full use there was nothing caught between my teeth, and that feeling made me want to use it again the next night.

Much less awkward than string

I never understood why floss needed both hands inside my mouth. This felt more natural because I hold it like a toothbrush and guide actual floss with one hand.

I was only flossing the easy teeth

With string I rushed the front and quietly skipped the very back, because my hands could not get into a comfortable position. My routine finally feels complete instead of almost complete.

I finally made it past day four

I was always good at starting to floss and terrible at continuing. This feels like one simple step instead of a separate project, so it has been much easier to repeat.

It sits next to my toothbrush

Floss used to be hidden in a drawer, which made it very easy to forget. This stays visible where I already brush, so the reminder is built into the space.

No more hands tangled in my mouth

Reaching my molars with string meant wet fingers, tight cheeks and losing tension halfway through. I can concentrate on where the floss is going instead of controlling both ends of it.
