Why does removal of plaque reduce the chance of forming cavities?
A) Plaque is a biofilm; it contains cariogenic bacteria, the metabolic byproducts of which facilitate tooth decay.
B) Plague causes a significant drop in oral pH. The more acidic condition causes tooth decay.
C) Plaque is a polysaccharide covering on tooth enamel. It contains tiny acid-soaked sponges that decay teeth.
D) Removing plaque involves brushing. A coincidental side benefit of brushing is removal all oral bacteria.
E) Removing plaque actually does not impact the development of cavities. Cavities have a genetic component and cannot be prevented.

Question

Quizplus · Accepted Answer

Plaque is a biofilm that contains cariogenic bacteria. These bacteria produce metabolic byproducts such as lactic acid which can dissolve the mineralized tooth structure and lead to tooth decay. Removing plaque reduces the amount of bacteria and their byproducts, thus reducing the chance of forming cavities.
