Tartar
sticks to teeth of even healthy people who conscientiously brush their
teeth after every meal. In technical lingo, this is called a calculus
deposit, caused by the interaction of saliva and food debris on the
surface of teeth. The surface of tartar is porous, similar to a pumice
stone, which permits the growth and propagation of bacteria. The bacteria
gradually spreads to the gums, causing them to become inflamed and bleed.
This inflammation of the gums damages the bone which surrounds and supports
the teeth. The bone then recedes, causing pockets between the teeth
and gums, which then causes puss to form, loosening the teeth. This
could lead to the loss of a tooth. A check-up at least once every six
months is recommended to prevent periodontitis.
