- Expanding floss means the strand widens as you use it. It's made of 250+ individually woven polyester filaments that spread apart between teeth, covering more surface area than a single flat ribbon or monofilament strand would.
- The polyester source material is made from recycled water bottles. Davids chose polyester over non-plastic alternatives (like silk or corn-based fibers) because they found those options didn't hold up to the mechanical demands of flossing.
- Coated in vegan wax and cocoa butter, so it glides rather than catches. The mint flavor comes from a blend of natural essential oils and has a mild, not overpowering, taste.
- Infused with nano hydroxyapatite to support remineralization in the tight spaces between teeth, where toothpaste typically can't reach. That's an unusual addition for a non-toxic dental floss; most flosses focus only on plaque removal.
- Sold as a refillable system: you buy the dispenser once, then swap in refill spools. The dispenser pops open for easy loading.
