What effect do sugar alcohols have on bacteria growth in the mouth?

Sugar alcohols inhibit the growth of bacteria in the mouth. Unlike traditional sugars, which can be fermented by oral bacteria to produce acids that contribute to tooth decay and cavities, sugar alcohols, such as xylitol and sorbitol, are not readily fermented by these bacteria. When sugar alcohols are consumed, they tend to disrupt the metabolic processes of harmful oral bacteria.

Xylitol, in particular, is of interest because it has been shown not only to inhibit the growth of certain bacteria but also to reduce the adherence of bacteria to tooth surfaces. This mechanism helps in reducing the incidence of dental caries and promoting oral health. Thus, incorporating sugar alcohols into the diet can be beneficial for maintaining a healthier oral environment compared to traditional sweeteners.
