Streptococcus is one of the most notorious bacteria found in our dental cavity and is known to give diseases like dental plaque. There are several antibiotics that are prescribed by the doctors to stop its growth, but of recently, the researchers have noted that polyphenols from tea and cranberries, and phenolic extracts from wine and grapes have restricted the growth of strains of Streptococcus. The researchers found that alcoholic or non-alcoholic red wine and the combination of wine and grape seed extracts were quite effective at fighting the bacteria.
So now we can say that while red wine was known to prevent heart diseases, it can also prevents dental cavity. Cheers!
