Definition of 'tartar'. tartar. Tartar is a hard yellowish substance that forms on your teeth and causes them to decay if it is not removed. If you describe someone, especially a woman in a position of authority, as a tartar, you mean that they are fierce, bad-tempered, and strict. She can be quite a tartar.
In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth. This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for further plaque formation. This leads to calculus buildup, which compromises the health of the gingiva (gums).
