Smart Floss
Dr. Tung's Smart Floss is the gold standard for 'expanding' floss, which stretches to fit tight gaps and expands in wider spaces to maximize surface contact. It is clinically proven to remove up to 55% more plaque than standard flosses.
Ingredients & Purity
Simple polyester fiber coated with a blend of vegetable and bees wax. It is gluten-free, PTFE-free, and BPA-free. Uses natural cardamom oil for flavor.
Scientific Evidence
Clinical trials specific to this product demonstrate a 55% increase in plaque removal compared to traditional floss. It is highly recommended by periodontists for patients with varying interproximal gap sizes.
Brand Transparency
While they don't publish full COAs, they are highly transparent about the absence of PFAS and the move toward eco-friendly cardboard packaging.
Value Assessment
Excellent value; usually priced around $5-6 for 30 yards, making it the most cost-effective high-performance floss on the market.
Why Not Alternatives?
Unlike competitors that use synthetic glides or rigid plastics, Smart Floss uses a proprietary polyester string that is softer on gums while providing a larger cleaning surface area. It avoids the chemical coatings found in major 'Reach' or 'Oral-B' products.
