Q: Is it true that white wine can stain your teeth?
A: Well, it's not just the white wine that can stain your teeth.
But, researchers at the New York University College of Dentistry
found in a study that drinking white wine can leave your teeth
susceptible to stains from drinking tea.
Though the study found that white wine remains preferable to red
wine in terms of the potential staining effect on teeth, it also
found that the acid content in white wine increases the risk of
staining from the chromogens that are in tea and other foods. The
researchers did not specifically test for coffee. They noted, however,
that the intensity of chromogens in coffee is not as strong as
those in tea. The researchers did their experiments on cows' teeth,
which, they said, have a surface similar to that of human teeth.
So, drinking white wine with fruit or cheese is not going to leave
you with stains. Researchers also noted that white wine drinkers
should wait 40 minutes to an hour before brushing their teeth to
give saliva the opportunity to remineralize the surface of the
teeth. Talk with your dentist about ways to avoid tooth staining.
