Can red wine help prevent cavities?
For anyone searching for another reason to enjoy a glass of red wine with dinner, here’s a good one: A new study has found that red wine, as well as grape seed extract, could potentially help prevent cavities. They say that their report, which appears in ACS’ Journal of Agricultural and Food Chemistry, could lead to the development of natural products that ward off dental diseases with fewer side effects.
M. Victoria Moreno-Arribas and colleagues explain that dental diseases are extremely common throughout the world. Cavities, periodontal disease and tooth loss affect an estimated 60 to 90 percent of the global population. The problems start when certain bacteria in the mouth get together and form biofilms, which are communities of bacteria that are difficult to kill. They form plaque and produce acid, which starts damaging teeth. Brushing, fluoride in toothpaste and water and other methods can help get rid of bacterial plaques, but the effects are limited. In addition, currently used antimicrobial rinses can change the color of the gums and alter taste, so people are less likely to use them for as long as they should. Some research has suggested that polyphenols, grape seed extract and wine can slow bacterial growth, so Moreno-Arribas’ team decided to test them under realistic conditions for the first time.
