Micronutrients & recovery
Non-nutritive sweeteners are less acidogenic than sugar and may increase oral pH, potentially reducing the risk of dental caries.
If you are concerned about tooth decay, switching from sugar-sweetened drinks to those with non-nutritive sweeteners is a beneficial change. The research indicates that NNSs produce less acid in the mouth than sugar, leading to a higher oral pH which is protective against cavities.
GoodSupportsHIGH confidence
all other studies described a less acidogenic (increased) oral pH after the intervention as compared to the sugar-containing control.
Why this rating
Based on 16 intervention studies (14 RCTs, 2 non-RCTs) showing consistent results on pH.
