oramd pure unwaxed, unscented dental floss-chemical-free, shred resistant(1 pc) oramd oramd dental floss is unscented, unwaxed, chemical-free, and fragrance-free. natural dental floss has a satin-like texture that is shred and break resistant. it effectively removes plaque, food, and foreign materials from between the teeth and just below the gum line. natural dental floss helps to keep teeth and gums healthy. some dental floss manufacturers coat their products in a teflon-like substance that contains highly toxic pfas. one study found that women who flossed with a popular brand of floss had higher levels of a chemical called perfluorohexane sulfonic acid (pfhxs) in their blood than women who didn’t use that type of floss. these chemicals have been linked to liver damage, harm to the immune system, developmental issues, cancer, and can persist in people’s bodies and environment for many years. the wax used in conventional floss is often 20% paraffin wax and 80% microcrystalline which are both derived from petroleum. microcrystalline waxes are derived from the refining of the heavy distillates from lubricant oil production. this by-product must then be de-oiled at a wax-refinery and then hydro-treated to remove odors.
