Dental Floss (Oral Care)

Floss is a thin strand drawn between two teeth to scrape the walls where they touch, and no bristle reaches those two faces. Tight contacts are its territory. Where two teeth press together with no visible gap, string is the only thing that fits at all.

Two filament types split the shelf. Multifilament nylon twists many fine strands together, usually waxed, and it grips plaque well while shredding on a rough filling edge. Monofilament PTFE is a single flat ribbon of the material used in nonstick coatings. It slides through a tight point without fraying and scrubs slightly less. Tape is simply a wider, flatter version for people with roomier gaps. Wax is a coating that eases the strand past a tight contact and takes a little grip away in exchange.

Break off about 18 inches, wind most of it onto one middle finger and the rest onto the other, then steer with thumbs and index fingers. Ease it through the contact rather than snapping it, because snapping cuts the gum. Curve it into a C against one tooth, slide two to three millimeters under the gum edge, work it up and down that wall, then move the C onto the neighbor. Both walls, every gap, a clean inch each time.

Where a gap has opened enough to admit an Interdental Brush, that brush cleans both walls faster and more completely. This makes floss the fallback there rather than the standard. A Water Flosser rinses debris out and does not scrape a film off a flat contact point, so the two never substitute for each other. Floss picks fix a short span in a plastic Y, which prevents a proper C shape and reuses one segment across every gap, though a pick used nightly beats floss left in a drawer.

Bleeding through the first week of daily flossing is common as inflamed gums firm up, and bleeding that continues past two weeks of consistent cleaning is a reason to see a dentist rather than to stop. Floss shredding in the same spot every night is reporting a rough filling or a broken edge, not a fault in the floss. Keep the container out of the shower, since steam softens the wax coating, and treat flavor as taste alone.
