Abstract
A toothpick has an elongated body portion having an upwardly extending ridge and a pair of angulated legs defining a longitudinal groove, a tooth gap traversing tip which is substantially flat relatively long and tapers to a point for substantially traversing the gap between adjacent teeth, and a tooth scraping tip which is substantially flat relatively short and tapers to a point for scraping adjacent tooth surfaces in an upward movement. The tips are substantially flexible perpendicular to the flat surfaces for adjusting to the curved surfaces which are encountered in the spaced between teeth. The tips are highly effective in removing food debris from the gap between tooth surfaces yet can be produced at relatively low cost from plastic.
