Cariology And Prevention 1 Practice Test

The key idea is the duration of exposure—the actual time sugar stays in contact with the tooth surfaces and plaque. When sugar is present in the mouth for a longer period, bacteria have more time to metabolize it and produce acid, increasing the risk of demineralization. Sticky or adhesive forms prolong this residence time, making the exposure last longer and enhancing cariogenic potential. Other factors influence how quickly sugar is cleared or how harsh the oral environment is, but they don’t determine how long the sugar itself remains in the mouth. Frequency affects how much sugar is delivered over time, but not the duration of each exposure. Saliva quality and flow help clear sugar and buffer acids, and pH affects the likelihood of demineralization, but the duration of the sugar’s presence in the mouth is what directly sets how long the teeth are exposed to cariogenic conditions.
