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 gumline. 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. Directions: 1.) Take an 18-inch piece of floss and tightly hold 1-2 inches between your thumbs and index fingers. 2.) Gently guide the floss between your teeth with a back and forth motion. When the floss reaches the gum line, curve it into a C shape against one tooth. 3.) Gently rub the side of the tooth, moving the floss away from the gum with up and down motions until clean. Then do the opposite tooth. Repeat for all teeth.
