Abstract
The floss is comprised of a texturized yarn that has been coated and impregnated with a water-soluble polymer and the water-soluble polymer coating cured and set while the yarn is stretched and is under tension. The yarn while stretched and tensioned is at a reduced width, which allows for easier insertion of the yarn floss between teeth. The yarn floss is wound onto a spool in the decreased width condition. For use, a length of floss is removed from the spool and placed between teeth. The saliva in the mouth dissolves the cured and set water-soluble polymer with the floss expanding to fill the space between the teeth. The floss is optionally coated with flavors, medicants and other substances. These can be synthetic or naturally occurring substances such as herbal substances.
