The Daily Mail claims:
believe it or not sparkling water is almost as damaging to your teeth as flavoured fizzy drinks. This is because your teeth are constantly being bathed in a weak acid solution containing carbon dioxide - thought to wear away our teeth. After repeated attacks over several years, this acid can erode the enamel - the hard part of our teeth made from calcium salts.
Is there any evidence that this is a significant cause of tooth damage, in the dosages one might expect to drink?
I know there are other questions asking about flavoured sodas (e.g. Does (diet) soda cause tooth decay?), however, my question is about unsweetened and unflavoured tap water, that has been carbonated with CO2.
