Abstract of the Disclosure A flat flexible strip has a length by means of which it can be reciprocated longitudinally in rubbing engagement with tooth surfaces. The strip is constructed of crossed strands forming cross ridges in surfaces of the strip that produce a frictional scrubbing engagement against teeth surfaces when the strip is reciprocated longitudinally. Strands can be arranged in a woven pattern or a haphazard pressed pattern. The edges of the strip are reinforced in a non-raveling structure. The strip may be of a width up to about 1/2 inch and a thickness up to about 4 mls.
