Unlike standard nylon flosses that can slice into gum tissue, the Smart Floss utilizes a patented expanding technology that cushions the contact while increasing surface area for cleaning. When compared to traditional plastic-bottled floss or synthetic PTFE tapes, this product offers a significantly lower carbon footprint and avoids the 'forever chemicals' often found in glide-style alternatives. It provides a tactile grip that outperforms silk-based options which can often be too slippery or prone to snapping.
"The expansion of the fibers makes a noticeable difference in how clean my mouth feels compared to thin tapes; it is the only biodegradable floss I've found that doesn't shred instantly." — Verified buyer
DrTung's utilizes a proprietary FSC-certified paperboard dispenser that eliminates the need for plastic waste. The floss itself is designed to break down in landfill conditions much faster than synthetic nylon, and the brand ensures that no animal byproducts like beeswax or silk are used in the manufacturing process, opting instead for plant-based waxes and natural cardamom oil for flavor.
To maximize the expansion of the fibers, ensure the floss is slightly damp from saliva or water before reaching the back molars, as the moisture triggers the widening of the weave.
Yes, Smart Floss is worth it because it is clinically proven to remove up to 55% more plaque than standard flosses while being eco-friendly.
No, DrTung's Smart Floss is completely free of PFAS, PTFE, and other harmful synthetic chemicals.
Smart Floss is ideal for tight teeth because the fiber remains thin when stretched but expands once it reaches the wider gaps between teeth.
Unlike silk floss, Smart Floss is 100% vegan and offers an expanding texture that captures more debris without the ethical concerns of animal harvesting.
Packaged in a biodegradable FSC-certified paperboard dispenser to eliminate plastic waste in oceans and landfills.
Contains natural plant wax and cardamom oil; free from beeswax, silk, PTFE, and PFAS chemicals.
