Abstract
Abstract A dental floss holder having a housing which forms a handle and supports a floss holding head as by a neck cantilever mounted on the housing. A pincer arranged in the housing is spring-biased to normally grip floss extending from a supply spool also arranged in the housing to the head and to retain the floss for being manually tensioned by a ring and clamp arrangement selectively clampable on a free end of the floss. The pincer is selectively releasable from the floss for passing clean floss from the spool to the head. The latter has a pair of spaced, co-directionally extending fingers forming a fork across which a length of floss is arranged for use. Each finger has a pair of floss guides provided thereon and arranged spaced from one another along the extent of the associated finger.
