We have all heard for many years that one small glass of red wine (3-4 ounces) each day may enhance your heart health, lower your cholesterol levels and may be associated with longevity.  Now we have see that red wine, as well as foods like grapes, apples and dark chocolate,  may have added benefit in keeping your mouth, teeth and gums healthy too.  Red wine appears to inhibit tooth decay and reduce the risk of gum disease by helping to counteract  the effect of Streptoccus mutans (S. mutans), a bacterial infection linked to tooth loss. 

Antioxidant chemicals called proanthocyanidins are found in red wine and other foods such as dark chocolate. These phytonutrients prevent S. mutans from sticking to saliva and teeth.  Italian researchers removed the alcohol from a high-quality Italian red wine. They added the nonalcoholic red wine to cultures of S. mutans in saliva, saliva-coated extracted teeth and saliva-coated calcium ceramic beads.  They found that the addition of the non-alcoholic wine prevented the bacteria from clinging to the saliva and to the teeth.  These investigators plan to extend their study to the effects of grape juice on S. mutans in the future.

Research from Cornell University and Université Laval in Quebec, Canada studied polyphenols, the chemicals in grape seeds and red wine that help neutralize the damaging effect of free radicals in the body.  Free radicals can damage our cells’ DNA.  Polyphenols from red wine also help control inflammation caused by gingivitis, or bacterial infections of the gums. Limiting inflammation may also protect against periodontal disease, a more serious form of gum disease that can lead to tooth decay or tooth loss, and has been linked to heart disease and stroke.

Unfortunately, the news is not as convincing when it comes to white wines.  White wines have lower concentrations of phytonutrients and polyphenols, and some researchers fear that the high acid content of white wine might help erode tooth enamel.

So smile tonight, when you have a small glass of red wine with your dinner and a half ounce of dark chocolate for dessert, knowing that your teeth and gums will be a little healthier. (don’t forget to brush and floss afterwards). Here’s a toast to staying healthy!
