Teeth cleaned of tartar (calculus) . Close-up of the lower teeth of a 30-year-old man, that have been cleaned of tartar. Tartar is a form of hardened dental plaque that builds up on and between teeth. It is caused by the precipitation of minerals from saliva and gingival crevicular fluid (GCF) from plaque. For the teeth before cleaning see C036/9112.
