A dental floss device for relieving the fingers from being tightly wound with floss and being in contact with wet and soiled spent floss comprises two sleeves--a take-up sleeve for receiving spent floss and a supply sleeve for containing pre-wound fresh floss and an end plug as a cover for the supply sleeve. The use of the device allows a strand of floss to be wound around the take-up sleeve and the end plug respectively instead of directly around fingers while flossing with the device is much the same as flossing with bare hands--a way of flossing which millions are used to. Further, the device is self-contained and reusable. When the supply of fresh floss on the supply sleeve is exhausted, a new pre-wound supply sleeve can be used to replace the exhausted one.

Dental floss device

A dental floss device comprises an elongated handle with a U-shaped flossing head projecting from one end of the handle. A strand of dental floss originated from a supply spool containing pre-wound fresh floss passes through the flossing head and emerges back to a take-up spool for containing spent floss. Dispensing floss and providing tension on the floss are controlled by the fingers of the holding hand on both supply spool and take-up spool which are rotatably mounted on the handle. The spools are also detachably mounted on the handle so that spent floss can be discarded and the take-up spool can be cleaned at will with ease and exhausted supply spools can easily be replaced with new, pre-wound spools like cartridges thus making the device reusable.
