Silk Dental Floss Refills

Silk floss is a fine, silk-textured thread coated in wax to help it glide between teeth. Traditional floss is nylon coated in a synthetic PTFE plastic — this floss is coated in plant-based candelilla wax instead, with no synthetic plastic coating.

Candelilla wax is a natural wax harvested from the candelilla shrub, used as a plant-based coating that helps floss glide smoothly between teeth. It replaces the synthetic PTFE coating found on most plastic floss — the typical source of PFAS chemicals in conventional floss.
