A proportionally wide strip of very thin and flexible material which is specially treated by mechanical, chemical or other means to form a multiplicity of folds, pleats, or channels along it's longitudinal axis and which is further intended to be pulled or drawn between teeth and along the gum line adjoining said teeth as an aid in the removal of trapped food particles and for the daily cleaning and removal of the build-up of plaque from these interdental areas; said device being further intended to spread, to roll-up onto, or to collapse upon itself by the means of increased or decreased pressure from external pulling force or from being drawn through the narrowed spaces between teeth; said ability to collapse and to roll upon itself is at once a better method to displace and/or to trap and contain bacteria, food particles, and other debris to be removed but also as a means to maintain contact with these surfaces while accomodating the variable spacing between teeth and between teeth and gums that is found in a normal mouth.
