Regular dental floss is made from either nylon (petroleum), teflon (the chemical mouthful polytetrafluoroethylene), or synthetic wax (petroleum). These toxins can be absorbed into your bloodstream during those times that you floss a little too hard, or it's been, say, longer than the dentist recommended since your last floss. And discarded dental floss cannot be recycled. In fact, it takes 30-80 years to break down and can be harmful to wildlife. Our corn fiber dental floss is lightly coated with candelilla wax for slide. It is compostable and can be purchased with a reusable glass vial.
