What’s the difference between plaque and tartar?

PLAQUE AND TARTAR CONTROL
We often confuse plaque and tartar and how they are related to eachother.
Plaque is a sticky, colorless deposit of bacteria that is constantly forming on the tooth surface. Saliva, food, and fluids combine to produce these deposits that collect on teeth and where teeth and gums meet.
The buildup of plaque can trap stains on the teeth, and it is also the primary factor in gum disease. Fighting plaque is a life-long part of good oral care.

Tartar, also called calculus, is a crusty deposit that can trap stains on the teeth and cause discoloration. Tartar formation may also make it more difficult to remove new plaque and bacteria.
