If this article is to be believed, then white wines could actually be worse for your teeth than red. Scientists have found that white wines such as Chardonnay and Pinot Grigio wear away tooth enamel more quickly than reds like Merlot and claret. Researchers have found that prolonged contact with white wine can erode the protective layer of enamel making teeth more sensitive to cold, hot and sweet food.
A team looked at the effects of eight red and white wines on the enamel of teeth removed from people between the age of 40 and 65. The teeth were soaked in the wine for up to 24 hours and then analysed to see how much damage had occurred. The teeth that had been soaked in the white wine had more damage than those soaked in the red. White wine has also been found to cause staining to teeth because the acids cause spots and groove in the enamel leaving them vulnerable to stains from tea and coffee. The good news, however, is that calcium rich food can offset some of the damage to teeth helping to prevent dental erosion. Next time I have a glass of wine, I will make sure I have a nice piece of cheese with it.
