I have been told that Carbon Dioxide (CO<sub>2</sub>) dissolved in [carbonated water](http://en.wikipedia.org/wiki/Carbonated_water) produces [carbonic acid](http://en.wikipedia.org/wiki/Carbonic_acid), that can attack your teeth enamel.

The [Daily Mail](http://www.dailymail.co.uk/health/article-113900/The-snacks-harm-teeth.html) 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. http://skeptics.stackexchange.com/questions/6191/does-diet-soda-cause-tooth-decay), however, my question is about unsweetened and unflavoured tap water, that has been carbonated with CO<sub>2</sub>.
