Final answer:
The ability of germs to produce dental caries is dependent on their ability to convert sucrose to lactic acid. Streptococcus mutans plays a significant role in this process, which leads to the degradation of tooth enamel and dentin.
Step-by-step explanation:
Part of the ability of germs to produce dental caries depends on their ability to convert sucrose to lactic acid. Dental caries, also known as cavities, occur when oral bacteria, most notably Streptococcus mutans, metabolize sugars such as sucrose. When sucrose is broken down by these bacteria, fructose is fermented, producing organic acids like lactic acid. These acids then dissolve the minerals in the tooth enamel and dentin, leading to tooth decay. It's important to reduce sugar consumption and maintain good oral hygiene to prevent the formation of dental caries and plaque, which can eventually harden into tartar.
Regular dental cleanings and treatments like fluoride can help strengthen tooth minerals and reduce the incidence of decay. Additionally, the use of sugarless candies or gum with sugar alcohols can reduce acid production, as these substances are fermented into nonacidic compounds.
