A new study in the American Chemical Society’s Journal of Agricultural and Food Chemistry shows that red wine and a grape seed extract would limit the growing of cavities. This can be a natural product that protect teeth against dental disease. Dental caries also known as tooth decay or a cavity, is an infection caused by bacteria. This starts as demineralization and causes destruction of the teeth. The very new research group grew a variety of bacteria, which they are source of tooth decay, and then dipped them in red wine with or without alcohol, and red wine spiked with grape seed extract. The result proved this idea that these two type of wines could thwart cavities, and slow down the bacterial growth for a while. Obviously, the tooth needs more dental care and filling to stop the dental caries permanently.
