TERRE HAUTE, Ind. (WTWO/WAWV) — The environmentally friendly nonprofit reTHink is not a fan of commercial dental floss, but not because it’s against good hygiene.

Traditional floss is housed in a plastic container that will sit around in landfills for hundreds of years before it degrades into micro-plastics, and the floss itself is made with non-biodegradable nylon, pieces of litter that have a tendency to be swept up in the disposal process and end up in the oceans. Floss can be a danger to marine life as it can strangle the animals or they end up eating it and it stays in their stomachs for years. 

Floss is also made with toxic ingredients like teflon and petroleum. Teflon exposure has been linked to cancers, hormone imbalance, autoimmune disease, neurotoxicity, and Alzheimer’s Disease. 

The reTHink Zero-Waste Shop has biodegradable floss available in reusable containers. One of the options is made of 100% silk that can be used in composts. The group offers a vegan option, as well. One package comes with a refillable container and two floss spools. reTHink sells just the spools as refills.
