A dental floss holder and applicator having a hollow handle for holding a supply of dental floss and a pair of intermeshing gear wheels mounted within the handle for advancing dental floss through a pathway which includes a dental floss anchoring member, a pair of prongs for holding a section of dental floss in position for use and a pair of intermeshing gears in the handle for pulling the dental floss through the pathway. The intermeshing gears are provided with a pawl for preventing the gears from reversing direction. The intermeshing gears not only advance the dental floss, but, in cooperation with the dental floss anchoring member, maintain it in tension while the floss is in use.
