ABSTRACT:
An improved dental flossing material and method of making the same is disclosed. The flossing material in the form of a tape is formed of expanded polytetrafluoroethylene (PTFE) folded longitudinally to form a pair of laminae defining a recess therebetween in which an abrasive or non-abrasive cleaning material is disposed. During the cleaning procedure, material flows from the free edges of the tape to become deposited upon the surfaces of the teeth and adjacent gingiva. Due to changes in light transmitting quality of the tape, a visual and reversible indication of prior use becomes apparent. In the manufacture of the tape, the PTFE, which is microporous, is coated on one surface thereof with a moist dentifrice which may be suitably thinned using a volatile vehicle. After folding, the moisture evaporates through the microporous structure to partially dry the dentifrice to a point where the abrasive particles attain a useful degree of shear, following which the finished article is enclosed in an airtight or hermetically sealed envelope to maintain a useful moisture level. Optionally, for greater longevity the dentifrice may contain a humectant.
