Abstract: A dental floss applicator is composed of a U-shaped frame of resilient material having a plurality of parallel slits in each one of the pair of holding arms. A plurality of unit lengths of dental floss are fastened in the slits of the arms thereby forming a dental floss curtain. The unit lengths ae provided with caps or beads at their ends and are of equal length. The interspace between a pair of caps or beads of each dental floss unit has an over-dimension with respect to the space between the arms of the frame. The unit is fastened at the frame by turning the unit at least partly around the base of each arm not containing the slit of slits thereby forming a 180.degree.-half-loop or a 360.degree.-whole-loop of the unit. The dental floss curtain provides for a better cleaning operation between the teeth and the new fastening mode guarantees a secure arrangement of the unit at the frame even when the unit is in a slack condition.

Abstract: A combined tooth brush and gum massaging device comprising a bristle head which includes an intermediate bristle portion and at both sides adjoining massaging portions, whereby the width of the bristle head is enlarged up to a value that the bristle portion can overlap teeth of the upper tooth row and teeth of the lower tooth row simultaneously when both tooth rows are in contact with one another. Therefore both tooth rows and adjoining gums can be treated simultaneously.
