Both red and white wines fight germs that cause sore throats and dental plaque.  In an article posted by Dr. Todd Welch in “Current Culture”, he pointed out that it is because of a mix of compounds that offer a persistent antibacterial effect. It’s not so much the alcohol and the acidity, but the combination of carbon containing compounds found in wine. Red wine has a more powerful combination than white, but not by much.  Now don’t start gargling with wine because the downside is the acids in the wine will soften your protective tooth enamel. It is suggested that you wait at least an hour before brushing after eating acidic foods and drinking wine. Same goes for brushing your teeth before drinking wine or any other acid product because it is the abrasion effect from the brushing which leaves the teeth unprotected. Let your saliva go to work for a while which can re-mineralize your teeth and prevent damage.

Don’t think that sipping white wine instead of red is going to help the look of your teeth because you can still get dark dental stains. The tannins present in wine, when combined with the acidity, hold compounds that saturate and weaken your teeth’s enamel. So when you have that cup of tea or coffee after dinner and that last glass of wine, you are helping to stain your teeth. A good thing for the cheese industry is that foods like cheese offset these compounds when they are served with wine, eliminating their staining effect.
