Tartar

 

solid deposits on the teeth of organic bases and salts (predominantly calcium phosphate) that have an irritating effect on the gums. Tartar appears on the necks of the teeth, but may also cover a considerable part of the crowns and roots; tartar can be deposited on dental prostheses when they are not cared for properly. Tartar forms when teeth are not cleaned sufficiently, fostering settlement on them of dental plaque (mucus, desquamated epithelium, microbes, food, and so on), which is then permeated with calcium salts that precipitate from the saliva. Tartar should be removed by a dentist to avoid gingivitis. It can be prevented by the normal act of chewing, the conscientious care of the teeth, and periodic examination by a stomatologist.
