Thus, it will be necessary to await the result of further research while the reason causing the bacteria to disappear in the face of acids is still unknown.
Naveed Sattar, professor of metabolic medicine at the University of Glasgow, also was skeptical about the study's findings, noting that there was no substantial evidence to prove that drinking wine overall was good for health.
They discovered that the wine polyphenols were generally better than the wine extracts at reducing the bacteria's ability to stick to the cells. "It starts with a white line just below the gum, which if you probe it is soft, and that is the beginning of tooth decay, which can lead to fillings and dental work", said Dr Mervyn Druian of the London Centre for Cosmetic Dentistry.
The high amount of vitamin C found in oranges, berries and lemons can also protect against tooth decay and gums from infections. Thus, the acids have been found to be very effective against the oral problems mentioned above, especially when they have been combined with a probiotic bacterium called Streptococcus dentisani.
Where you find Polyphenols from? . "Therefore, until the benefits of this research are shown clinically, it is best to consume wine in moderation and with a meal to minimize the risk of tooth erosion".
It was this suggestion that led the researchers in Spain to investigate whether wine polyphenols would also protect teeth and gums, because before food reaches the gut, the chemical breakdown begins in the mouth.
"In fact, the acidic nature of wine means that consuming a lot of these drinks will damage the enamel of the teeth", he told the BBC. Red wine, in particular, is abundant in polyphenols, which is why people often choose these varieties for health purposes.
