Vaping and the oral microbiome: changes observed, but no clear evidence of harm
The debate on e-cigarette use and oral health continues, with a recent CoEHAR review focusing on vaping's impact on oral microbiota. While e-cigarette users show varying oral microbiota compared to non-smokers and smokers, the changes lack consistency, making it hard to pinpoint a definitive vaping-related bacterial profile. Changes in the oral microbiome don't necessarily indicate disease, and definitive conclusions on vaping's oral health effects are limited by small, cross-sectional studies. More extensive, longitudinal research is needed to understand the long-term risks associated with vaping on oral health. Prof. Polosa emphasizes the preliminary nature of claims linking vaping to oral harm, indicating a need for stronger evidence.
