You may be told that having red wine during dinner is good for your health, in fact, the polyphenois it contained was believed to increase HDL cholesterol and strengthen artery linings. These findings were derived from studies viewed through the perspective of the lipid hypothesis, which is now under contention by the medical community.
A particular polyphenol known as resveratrol helped reduce inflammation and diabetes risk in mice. However, research by the Mayo Clinic indicated that people would have to drink more than 1,000 liters of red wine per day to match the amount provided to mice.
So is red wine bad for your teeth? The answer is yes and the main reason is acid. The PH of red wine is positioned between 3.0 and 3.5. When the level is this low, it means the beverage is highly acidic. The corrosive effect of wine encourages bacterial growth, increasing the risks of cavities and bad breath. Drinking sugar or carbonated beverages makes matters worse. In more austere cases, the chronic erosion will lead to the exposure of underlying dentin in the teeth, which will be highly sensitive and require root canals.
With proper oral hygiene, you can alleviate many of the negative effects of red wine. Brush your teeth 2-3 times per day. You can also try drinking with a straw. Ask your dentist as well about how to maintain healthy teeth after drinking wine.
