Davids Expanding Dental Floss with Hydroxyapatite is 66 yards of vegan, woven-strand floss in a refillable metal dispenser. The expanding fiber catches in tight spaces and broadens to clean wider gaps in a single pass — no shredding, no breaking mid-tooth, no stringy single strands stuck in molars.
It’s the right floss for users who’ve broken cheap drugstore floss in tight tooth gaps or who want a cleaner ingredient list — waxed in cocoa butter and natural mint, with hydroxyapatite (the same enamel-rebuilding compound as Davids’ toothpaste) embedded in the fiber. The refillable dispenser cuts plastic waste compared to single-use floss containers.
Davids Premium Oral Care is an American natural oral-care brand. The expanding floss is part of the broader Hydroxi line — fluoride-free, SLS-free, made in the USA, with refillable packaging that matches the brand’s reduced-waste positioning.
