An orthodontic flossing implement for facilitating positioning and manipulating of a portion of a length of dental floss into the interdental space between adjacent teeth and proximate to and beneath an orthodontic wire which defines an arch extending between adjacent orthodontic brackets on the teeth. An elongated handle dependently supports an elongated, slender shaft formed as a unit with, and extending from a proximal end of the handle. The shaft is dimensionally smaller in thickness than that of said handle and preferably oriented at an acute angle to the handle. A tip, formed as a unit with, and extending from a second end of the shaft, is oriented at an acute angle to the handle, the tip having an aperture formed therethrough sized to just receive a length of dental floss. The tip with the dental floss positioned through said aperture, is manipulable by said handle to pass beneath an arch of the orthodontic wire and to floss the interdental tissue.

Individually packaged coils of dental floss are packed in a succession of separable. The package can be a tubular sheet structure with segments formed between transverse lines of attachment at which the floss is cut and the segments are separable by a lateral perforation. Tearing a separated single segment in half allows the floss to be extended between the free ends of the floss, each captured in the remaining portions of the weld lines at opposite ends of the segment. The segments can be formed from two facing sheets with welds along both lateral edges and across the transverse lines between segments. Alternatively, an integral sheet can be folded to form one lateral edge and attached at the other edge. The sheet material can be polymer coated paper or a transparent plastic.

The invention relates to a toothbrush head having a bristle carrier on which tufts of bristles are arranged, the bristle tufts having a plurality of filaments, wherein at least one of the filaments has a tapering portion towards its free end; the present invention The invention also relates to a toothbrush with such a toothbrush head. It is disclosed that at the tip of at least one filament, the tapered portion is given a profile deviating from a rotationally symmetrical shape in order to maintain a high bending stiffness of the filament in one direction. According to the invention, the constriction is formed in the form of a coined sharpening, so that the filaments in the region of the constriction relative to the first transverse axis are more rigid than in the region of the constriction relative to the second transverse axis perpendicular thereto. Has greater bending stiffness. The cross-section of the filament in the region of the coining sharpening has a longitudinal axis or major axis and a shorter transverse axis or minor axis, so that the filament obtains different planes in the region of the sharpening with respect to the two said axes moment of inertia. The coined sharpening at the tip of the filament facilitates the insertion into the interdental gap, and here the high areal moment of inertia of the broad sides prevents bending.
