In the study, scientists used Pinot Noir red wine, both with and without alcohol, to assess its impact on biofilms of disease-causing oral bacteria collected from five volunteers. Biofilms are sticky layers of bacteria that play a major role in tooth decay and gum disease.

The researchers immersed these bacterial biofilms in different solutions and observed how the bacteria survived and grew. The results were interesting:
Red wine—both alcoholic and alcohol-free—as well as wine combined with grape seed extract, significantly reduced decay-causing bacteria.

What Does This Mean for Oral Health?

These findings suggest that certain natural compounds found in red wine and grape seeds may help limit the growth of harmful oral bacteria. This adds to existing research highlighting red wine’s potential health benefits, which are already known to include cardiovascular support when consumed in moderation.

However, it’s important to remember that red wine is not a substitute for good oral hygiene. Wine is acidic and can still stain teeth or contribute to enamel wear if consumed excessively.
