What role do sugar alcohols play in dental health?

Sugar alcohols, such as xylitol, sorbitol, and erythritol, play a beneficial role in dental health primarily by inhibiting the growth of bacteria that cause tooth decay. These sugars are not fully metabolized by oral bacteria, which means they do not produce the acids that lead to enamel erosion. In fact, some sugar alcohols, particularly xylitol, have been shown to disrupt the metabolic processes of cavity-causing bacteria, making them less harmful to dental health.

Unlike traditional sugars that can promote dental plaque formation and fuel harmful bacteria, sugar alcohols can actively contribute to maintaining oral hygiene. They may even promote the remineralization of tooth enamel, providing an additional protective effect against cavities. Therefore, the role sugar alcohols play in dental health is significant in preventing decay and supporting overall oral health.
