Did you know that not only does conventional nylon dental floss take 50-80 years to decompose? Conventional dental floss is made from what's most commonly known as Teflon. Teflon is basically a synthetic chemical known as Polytetrafluoroethylene (PTFE) commonly used in non-stick cookware. Teflon has been linked to a number of health problems including the common flu (otherwise known as the 'teflon' flu). Moreover, as a component of dental floss, Teflon can be absorbed into your bloodstream while flossing.
