Water-Expanding Tech: Engineered to expand instantly upon contact with moisture, growing in volume to fill the gaps between your teeth for a gentler and more complete clean.
Soft & Spongy Texture: Once expanded, the fibers transform into a soft, cushion-like texture that is incredibly gentle on sensitive gums while still being tough on plaque.
288 Micro-Fibers: Designed with a dense network of 288 textured nylon fibers that sweep away debris more effectively than traditional thin flosses.
Natural Beeswax Glide: Coated in a natural beeswax blend, it slides easily into tight spaces before expanding to do its best work.

Why flossing is essential

Brushing only cleans the surface. But plaque builds up between your teeth, where your toothbrush can’t reach .

Flossing removes it, helping prevent cavities, bad breath, and gum problems for a healthier mouth overall.

Commonly Asked Questions

1) How does the expanding fiber work?

PuffClean goes in thin and dry, then its fibers bloom with moisture into a soft, cushiony texture that sweeps a wider surface for a gentler, more thorough clean than standard floss.

2) Is it good for sensitive gums?

Yes. It’s our gentlest floss. The cushioned fibers wrap softly around each tooth instead of scraping, which makes it ideal for tender or easily-irritated gums.

3) Will it fit tight teeth?

Because it enters thin before it expands, it works for most gaps. For very tight contacts, our flat SlimWeave ribbon slides in more easily.

4) Is it PFAS-free?

Yes. PuffClean is made from nylon fibers with no PTFE or fluorinated coatings, finished with a natural beeswax blend.

5) Does it have a flavor?

Yes. Infused with natural mint and xylitol for a fresh finish.

6) How long does a 3-pack last?

Three spools of 55 yd each, so with daily use roughly six months for one person.
