Noncariogenic carbohydrate sweeteners do not promote dental caries.
Is it true that Noncariogenic carbohydrate sweeteners do not promote dental caries?
Yes. Noncariogenic carbohydrate sweeteners such as xylitol and sorbitol do not promote dental caries and instead help prevent them by failing to act as substrates for oral bacteria.
Verdict: SUPPORTED · 8 sources for, 0 against · Last checked
The claim is specific and falsifiable, passing Step 0. Multiple reviews, clinical studies, and microbiological papers consistently demonstrate that noncariogenic sweeteners (such as xylitol, sorbitol, and other sugar substitutes) either fail to promote or actively help prevent dental caries compared to fermentable sugars like sucrose. There are no papers refuting this well-established consensus.
