Abstract
Abstract An oral hygienic device comprising an elongated member having a tapered rounded end capable of being inserted within the spaces between a user''s teeth, with a hook at the opposite end thereof having sufficient space for receiving a length of dental floss. The tapered end has a blade or reduced edge for scraping food debris, bacterial plaque and residue from a user''s teeth. The intermediate section of the device is relieved with stippling or cross-hatching on either or both sides to provide a roughened portion capable of gently abrading extraneous material on and between a user''s teeth. A second embodiment comprises an elongated device having a pointed end and a tapered portion internally bevelled or curved to provide a hollow terminating in an edge, with a handle at the distal end thereof having a relieved portion for gripping ease. The second embodiment also has stippling along the blade which serves to remove food debris, bacterial plaque and residue from a user''s teeth.
