The drink has a component that attacks the DNA of bacteria that cause cavities and gingivitis
We’ve already talked about it: drinking wine can make your life happier (even with that talk that “drinking a glass a day is good for the heart” is not true ). Now, a new study is indicating yet another benefit of the drink: wine can do good to the teeth.
The statement comes from a survey conducted by the American Chemical Society (an NGO founded by the American Congress in 1876, with the proposal to promote scientific studies) in partnership with the University of Madrid. According to the results of the study, polyphenols (components present in wine) help keep bacteria harmful to oral health away from your mouth. The idea is that these substances make the bacteria lose their ability to stick to mouth surfaces, such as the gums and their teeth.
Adherence in the mouth is essential for the survival of harmful bacteria. In general, the bacteria cling to the teeth and from there they begin to multiply and colonize an increasing area. Eliminating their ability to cling to their teeth, then, ends the problem.
The researchers removed polyphenol molecules from red wine samples and put them in contact with bacteria S. mutans and S. dentisani , responsible for the development of gingivitis and caries. It was then observed that the polyphenols, in contact with the microorganisms, reacted chemically by producing hydrogen peroxide molecules – damaging the DNA of the bacteria. More specifically, it harmed the bacterial genetics just responsible for the adherence in the mouth.
The results, however, are not definitive. The researchers themselves understand that the sample of conclusions is limited because the study was not tested effectively in a mouth, but in controlled environments. And, of course, scientists do not recommend switching toothpaste for wine – on the contrary, too much alcohol can harm dental health. But at least you already have an excuse for the next time someone else will make fun of you for the good purple coming from a glass of wine. Cheers.
