Where Gum Health Begins
~40% of each tooth's surface is missed by brushing alone.
The areas most vulnerable to gum disease sit between teeth and along the gumline.
Flossing supports teeth, but it's essential for gums.
Our floss is designed to care for both.
Innovation In Every Strand
Clinically demonstrated to outperform smooth, single-strand floss.
Widens during use to reach more of the tooth surface and gumline.
Textured strands create light friction to lift plaque linked to gum inflammation.
Gentle fibers protect delicate tissue without sacrificing performance.
Plant-based wax helps slide through tight spaces for a more comfortable experience.
Helps inhibit microbial buildup, keeping the strand fresher during use.
Naturally flavored and thoughtfully chosen.
Free of PFAS — the synthetic "forever chemicals" found in many conventional flosses.
Made with post-consumer recycled yarn from plastic bottles collected in northern Italy — turning waste into something that works harder.
