Abstract
Abstract A sanitary, hygienic dental/oral appliance synergistically combining six functions in one device to conveniently and even disposably provide for complete dental/oral hygiene in a portable package. A complete dental/oral hygiene device comprising a hypotraumatic (non-abrasive), large working/brushing-surface headpiece mounted upon a shaft. The shaft proximal end is adapted for scraping and stain removing. A flexible toothpick mounted upon the shaft as well as a measure of dental floss with a cover to hold the floss in place. Also described as a fibro-cellular (spongy), bristle-free, first absorbent toothbrush, preimpregnated with fluoride gel/toothpaste, combined with a novel "winged toothpick", dental floss, stain scraper & gum/teeth stimulator/vibrator tips, for easy-to-use, economically very pleasant, pain-free, comprehensive & complete dental/oral hygiene program.
