Stones (tartar) are hard deposits formed when microbial dental plaque calcifies (calcifies) if not removed from the teeth. When plaque calcifies, the bacteria in it lose their effectiveness and cannot synthesize disease-causing toxins.
However, although this may seem to protect the health of the gums, it is not as it seems. Since tartar has a grooved surface, it creates a suitable environment for newly formed plaque to adhere to. Moreover, since the plaque that accumulates on the tartar can no longer be removed with a toothbrush and dental floss, it calcifies after a while and becomes a part of the stone underneath. Tartar continues to accumulate in this way. The result is that the symptoms of inflammation in that area appear more severely.
