Title: hard on fillings!
Review: I drank from klean cantine for about a month. In the first week my fillings started getting sensitive. I didn't connect the two, however, it was quite immediate. I even went to the dentist who said he saw nothing and thought I may need a root canal! Then I thought about the water, stopped drinking from it, and my teeth are just returning to normal over a month later.In short, buy at your own risk.Me, I went SIGG.
Is the review positive or negative?
