PCT No. PCT/US97/17534 Sec. 371 Date Feb. 3, 1999 Sec. 102(e) Date Feb. 3, 1999 PCT Filed Sep. 30, 1997 PCT Pub. No. WO98/14133 PCT Pub. Date Apr. 9, 1998A novel dental floss and gum massager made in the form of a strand, a tape or a sheet of polymeric material, said sheet having selectively positioned multiple sized holes for inserting though and holding by the fingers of the hands. The floss provides substantially very little constriction of blood flow surrounding the fingers as the floss is held taught and the peripheral edge of the floss is being manipulated and worked by the gripping, pulling, pushing, deforming, and guilding back and forth actions of the fingers during massaging of the gums and flossing of the teeth.
