Davids Hydroxi™ expanding floss is meticulously designed for high performance. It’s woven 250+ strands of soft (yet gently scrubby) threads....and coated in smooth wax infused with cocoa butter and nano hydroxyapatite. The wax and cocoa butter allows the floss to glide smoothly between your teeth, and nano hydroxyapatite works to remineralize enamel in those hard-to-reach crevices. Davids floss is free of harmful teflon or PFAS, making it a safe dental floss for your whole family. Refill and reuse your floss dispenser with this 2 pack of floss refills.
