Dental Lace Silk Floss
Silk thread in a refillable glass vial - a natural protein fiber that can't be a fluoropolymer, so it sidesteps the whole PTFE/PFAS question the way no plastic floss can.
The verdict: Plastic-free
This is as plastic-free as floss gets. The thread is 100% silk - a natural protein fiber, which by construction cannot be a PTFE fluoropolymer, so it sidesteps the PFAS question entirely rather than merely testing low. It's coated in candelilla-family plant wax with mint, and the packaging is a refillable soda-lime glass vial with a stainless-steel cutter cap. Nothing in the contact path - or the package - is plastic, and refills arrive in a compostable bag so the vial is reused indefinitely.
What it's made of
| Part | Material | Skin contact |
|---|---|---|
| thread 100% silk | Silk | Yes primary |
| coating plant wax + mint | Candelilla Wax | No |
| vial refillable glass | Soda-Lime Glass | No |
| cutter cap steel cutter/cap | Stainless Steel grade unspecified | No |
A refillable floss dispenser: a small glass vial with a stainless cutter in the cap, filled with waxed silk thread. When it runs out you drop in a paper-wrapped refill spool rather than buying a new dispenser, and the empty refill packaging is compostable. The silk is finer than most plastic floss, so it slides into tight contacts and frays as it wears.
Pros
- Silk thread can't be a fluoropolymer, so PFAS is a non-issue by construction
- Refillable glass vial reused indefinitely; refills ship in a compostable bag
- Plant-wax coating and steel cutter mean the entire package is plastic-free
Cons
- Fine silk can shred or snag on rough fillings and tight crowns
- Costs more per use than a spool of drugstore plastic floss
Notes
- A vegan version made from PLA (corn bioplastic) is also sold for those who avoid silk - it's compostable but still a polymer thread, an honest middle option rather than a plastic-free one
