PRIMALS Gum Guard Silk Floss - Midnight Mint (82 ft)

Gum Guard is 100% mulberry silk with a hydroxyapatite coating. It cleans between your teeth and along the gumline, the two surfaces your brush can’t reach, without dragging nylon, Teflon or PFAS across your gums. Silk grips and lifts plaque, and the mineral coating helps it glide into tight gaps without snapping or shredding.

Most floss is nylon or PTFE (Teflon) string, and many popular brands are coated in PFAS “forever chemicals” for their slick glide. A 2019 study of 178 women found those who used a PTFE floss tended to have higher PFAS levels in their blood. Many are also finished with petroleum wax, and the plastic never breaks down.

Silk was the original floss. Dentists recommended silk thread in the early 1800s, long before nylon replaced it in the 1940s. It’s a natural fiber that’s soft on the gums and breaks down naturally instead of sitting in a landfill.

It’s the same mineral your tooth enamel is made of. We coat each strand with it so the silk glides smoothly between even the tightest teeth. Most floss skips it.

In it: mulberry silk, coconut oil, carnauba wax, hydroxyapatite, charcoal powder, propolis extract, black seed oil, erythritol, peppermint oil and vanilla.

Not in it: no nylon, PTFE, PFAS, plastic, petroleum wax, synthetic dyes, artificial flavors, parabens or phthalates.

Pull out about 45 cm and wind it around your middle fingers. Guide it gently between your teeth, never snap it, and curve it into a C-shape against each tooth, sliding just under the gumline. Use a fresh section for each gap.

It contains silk and propolis (bee resin). If you’re allergic or sensitive to either, don’t use it, and stop if any irritation occurs. Because of the silk and propolis, it’s not vegan.

Keep it away from children under 6. Older kids can use it with an adult supervising until they’ve learned to floss gently. For oral use only. Don’t swallow the floss.

One glass jar with a steel lid holding 25 m (82 ft) of Midnight Mint silk floss. At about 45 cm a day, that’s roughly 55 uses, or close to two months of daily flossing. Keep the lid closed so the silk stays clean and dry.
