Abstract
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.
