You also forgot carbolic acid. I don't think it reacts well with teeth in the long run. With regular sodas, and in particular 'Mountain Dew', you have a problem with the sugars that end up hanging around the base of your teeth. People who drink large quantities have what dentists call 'Mountain Dew Mouth'. The teeth are rotted around the base. The next thing you might want to look at is 'acid reflux disease'. This is hearsay from a dentist, but he said 'look at the increase in soda consumtion and the increase in acid reflux.' Apparantly, they follow the same path on a chart. Bottoms up, DL
