Abstract
An elongated handle with an internal supply of fresh dental floss and a flossing head including a fork provides oral hygiene. A fresh section of floss is advanced by a one-touch arrangement which concurrently relegates spent floss to a separate take-up reel. The fresh floss spanning the tines of the fork is kept taut at all times as a result of various special expedients including a differential spool and drum and a rack and pinion floss locking arrangement. When the supply of fresh floss on the bobbin is exhausted, the device is discarded.
