True or False: Sugar alcohols are cariogenic.

Sugar alcohols, such as xylitol, erythritol, and sorbitol, are not cariogenic, meaning they do not promote tooth decay. This is primarily because sugar alcohols are not fermented by oral bacteria in the same way that traditional sugars are. When bacteria metabolize sugars, they produce acids that can lead to the demineralization of tooth enamel, which is a crucial factor in the development of cavities. Since sugar alcohols do not contribute to acid production in the mouth, they are often used in sugar-free products and are even promoted for their benefits in dental health.

Moreover, xylitol, in particular, is noted for its potential to inhibit the growth of Streptococcus mutans, a primary bacterium associated with tooth decay. This property makes sugar alcohols a favorable alternative to sugar in a diet aimed at reducing the risk of dental caries.

The incorrect options imply either an affirmative stance on sugar alcohols being cariogenic or a conflicting assertion about their nature which doesn't align with established understanding in nutritional science regarding dental health.
