Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Polyalditol is a term often used to refer to sugar alcohols such as xylitol, sorbitol, and maltitol. Among these, xylitol is particularly well-studied for its dental benefits. The scientific validation for the use of xylitol in supporting oral health, especially teeth, is robust. Multiple clinical trials and systematic reviews have demonstrated that xylitol helps reduce dental caries (tooth decay) by inhibiting the growth of Streptococcus mutans, the primary bacteria responsible for cavities. Xylitol is non-fermentable by oral bacteria, which means it does not contribute to acid production that erodes tooth enamel. Moreover, regular use of xylitol-containing products like chewing gum or toothpaste has been shown to lower the levels of harmful bacteria in the mouth and promote remineralization of enamel.

The American Dental Association and several international dental organizations recognize xylitol's role in caries prevention. However, not all polyalditols have the same level of evidence; xylitol's benefits are most substantiated, while others like sorbitol are considered less effective and may even be fermentable by some oral bacteria. In summary, the use of polyalditol—particularly xylitol—is scientifically validated for supporting the teeth body system, primarily by reducing caries risk and supporting overall oral health.
