    Fluoridated water is said to contain fluoride at a level at which it is effective for preventing cavities. This can at times occur naturally and (most commonly) when it is added by an outside source. Generally, a fluoridated compound is added to public drinking water and costs America around 95 cents per-person year.

    The recommended level is 0.5 to 1.0 mg/L. but at times bottled water has fluoride added that is not labeled so it is difficult to speak for everyone distributing the product.
