Acidity of White Wine Can Erode Tooth Enamel

Posted on October 21, 2009

BBC reports that researchers have found drinking white wine can be bad for your teeth. They found that the high acidity levels in white wine erode tooth enamel more quickly than red wine. They also say brushing your teeth afterwards can just make things worse. However, if you eat cheese or creamy desserts with the white wine it can reduce the acid from the white wine.
In the lab, adult teeth soaked in white wine for a day suffered a loss of both calcium and a mineral called phosphorus to depths of up to 60 micrometers in the enamel surface, which the researchers say is significant.

And the matter isn't helped by brushing your teeth soon after drinking, as excessive brushing action can lead to further loss of enamel. Also the effects can be made worse by how frequently you sip your wine.

But the study wasn't all bad news for wine lovers. By having cheese or creamy desserts, the acid attacks can be reduced.

"The tradition of enjoying different cheeses for dessert, or in combination with drinking wine, might have a beneficial effect on preventing dental erosion since cheeses contain calcium in a high concentration," the scientists added.
The Telegraph says the study involved soaking teeth in wine for 24 hours. If you are going to drink white wine it might be wise to also eat some delicious cheese along with it.
