Is Dr. Tung's Floss Clean?

The Short Answer

Dr. Tung’s Smart Floss is clean, non-toxic, and highly effective. It completely avoids the forever chemicals and petroleum-based waxes that plague the conventional oral care aisle.

But eco-conscious buyers should know it is made of polyester plastic. While it comes in a zero-waste cardboard dispenser, the floss itself will never biodegrade.

Why This Matters

The dental floss industry has a massive chemical problem. Brands like Oral-B Glide use PTFE (Teflon) to make their floss slip smoothly between teeth, which exposes users to high levels of PFAS "forever chemicals." Is Glide Floss Safe

Consumer testing has found up to 248,900 parts per million of organic fluorine in conventional glide-style flosses. Because floss goes directly into your mouth and micro-cuts your gums, these chemicals have a direct pathway into your bloodstream. Is There Pfas In Floss

Dr. Tung's takes a completely different approach. Their patented design clinically removes up to 55% more plaque than standard floss without relying on toxic lubricants. Which Floss Has Pfas

What's Actually In Dr. Tung's Floss

Instead of chemical coatings and artificial mint flavors, Dr. Tung's keeps their ingredient list short and natural. What Floss Is Pfas Free

• Multifilament Polyester — A durable plastic fiber that expands to grab plaque. It is safe for your body, but it is not biodegradable.
• Vegetable & Beeswax Blend — A natural alternative to the petroleum waxes used by mainstream brands. It combines beeswax with candelilla, carnauba, and castor oil. Waxed Vs Unwaxed Floss
• Cardamom Essential Oil — Provides a naturally fresh flavor. It completely avoids the synthetic artificial flavors found in standard floss.

What to Look For

Green Flags:

• PFAS-Free Testing — Dr. Tung's tests below detectable limits for organic fluorine.
• Natural Waxes — Plant and beeswax blends are significantly cleaner than microcrystalline (petroleum) wax.
• Plastic-Free Packaging — The FSC-certified paperboard dispenser eliminates single-use plastic waste.

Red Flags:

• Polyester Fibers — The actual floss string is plastic and contributes to microplastic pollution in landfills.
• Beeswax (For Vegans) — The standard Smart Floss is not vegan, though they do offer a plant-based alternative.
