摘要:
To properly remove food deposits, dental plaque and calculusaway from the very narrow gaps between adjacent teeth, a tooth pickis provided, which is thin and rigid enough, so that it can be pushedthrough these very narrow gaps between the teeth. In its basic form,the tooth pick is a strip of hard metal and at least one of its endsis formed in such a way that it is able to push and/or scrape awaythe food deposits, dental plaque and calculus from these gaps betweenthe teeth. Additionally, at least one of the longitudinal sides ofthe strip can be formed in such a way it has at least one tooth-typeprotrusion feature, which also have shapes and edge qualities, whichwill make it possible for the tooth pick to remove food deposits,dental plaque and calculus both in push and pull directions.
