Quizplus · Accepted Answer

Dental plaque is a biofilm that consists of bacteria surrounded by a polysaccharide matrix. While sugars contribute to the formation of plaque, they are not the only component. Lactic acid may be produced by the bacteria within the plaque, but is not a component of the plaque itself. Fluoride is not typically a component of plaque. High pH would be unlikely, as acidic conditions are more conducive to plaque formation.
