According to a Spanish research, led by Dr. Victoria Moreno-Arribas from the Spanish National Research Council in Madrid, drinking red wine may protect teeth by destroying bacteria causing cavities and gum disease.
The researchers completed an experiment where they tested concentrations in the range normally found in wine – 50 and 10 µg/ml. While working with cells that modeled gum tissue, the researchers have found the two wine polyphenols, caffeic and p-coumaric acids, were generally better than the total wine extracts at cutting back on the bacteria’s ability to stick to the cells.
Results of the study also suggest that antioxidants in red wine are more efficient than grape-seed and red-wine extracts at preventing plaque-causing bacteria from sticking to lab-grown cells in modeled gum tissue.
According to a recent study, published in the journal Pediatrics, children who are breastfed for 2 years or more are at higher risk of having dental cavities later.
For the research, a team of scientists analyzed breastfeeding habits and sugar consumption for 1,129 children in a city of Pelotas, Brazil. Having analyzed the given data, the researchers concluded that children who were breastfed for 2 years or longer were 2.4 times more likely to have severe cavities than children who were breastfed for less than a year.
Dr. Karen Peres, a lead author of the study and an associate professor at the University of Adelaide in Australia, explains: “There are some reasons to explain such an association. First, children who are exposed to breastfeeding beyond 24 months are usually those breastfed on demand and at night. Second, higher frequency of breastfeeding and nocturnal breastfeeding on demand makes it very difficult to clean teeth in this specific period.”
