The World's Only 3-in-1 Floss Head

Every Slate floss head is three tools in one and is designed to be rinsed and reused for up to a week. That means less waste than disposable floss picks and an easier routine to stay stocked on.

Slate 3-in-1 floss head: woven floss, gum brushes, and tongue scraper

1 / 3

CHEMICAL-FREE WOVEN FLOSS

No PFAS, no PTFE, no wax. Just floss that's safe to reuse all week.

2 / 3

Tongue Scraper

Because a cleaner mouth is not just about your teeth. Slate’s built-in triple-row tongue scraper helps remove leftover bacteria and complete your routine in one tool.

3 / 3

Patented Gum Sweeps

The soft silicone gum brushes help massage and stimulate the gumline while sweeping away plaque and buildup. It’s one of the biggest reasons Slate feels different — and cleans more completely.

Three tools. One reusable floss head.
