ABSTRACT:
The dental flossing device comprises an elongated cylinder, at least a portion of which is hollow, with an extension having a forked end with curved prongs. A commercially-available spool of floss is located on a spindle in the hollow portion of the cylinder. A first locking mechanism holds the floss in a small space between two surfaces with sufficient friction to firmly retain the floss. When relaxed, the floss can be readily pulled through the first locking mechanism. The floss is fed to the exterior where it is stretched across fork prongs. The floss is threaded through a second locking mechanism similar to the first. The two locking mechanisms are controlled by a single external control and, thus, are both activated or deactivated at the same time. They oppose each other, pulling different points on the floss to create and maintain a strong tension in the floss where it spans the fork, thus facilitating flossing. An alternate embodiment has a removable disposable extension and forks for use by dental professionals. A floss spool is contained within the disposable portion of the device as well as an uptake spool. Floss is advanced by an electrically-powered motor.
