It seems most wine makers and tasters know this for a fact. White wine has far more acidity levels than red wine, which creates an acidic punch and attacks the tooth enamel and cause erosion.
It is not the white wine’s alcohol levels, date of manufacture or origin, but its pH level and the overall contact duration with the teeth.
White wine attacks calcium in teeth, therefore, eating cheese at the same time may counter and reduce the damaging effects, because cheese is rich in calcium and is proven to help maintain good oral health.
If you are having white wine, it is recommended you do so with your meal and brush your teeth at least half an hour after the meal, as per another study conducted by Goettingen University in Germany.
Having your white wine together with food, rather than on its own, stimulates the production of saliva which naturally helps tackle the excessive acidity in the mouth and lower its erosive potential.
In the Johannes Gutenberg University laboratory the teeth was soaked in white wine for a day, the experiment showed a considerable lowering in tooth dental enamel surface of 60 micrometers, which researchers concluded to be significant. Riesling showed to be ‘kinder’ tooth option, as it proved to have a minimal impact on pH levels in the mouth.
