FDA Regulations on Fluoride in Bottled Water

Some bottled water contains fluoride and some does not, depending on the source of the water and whether fluoride is added. The Food and Drug Administration (FDA) regulates fluoride in drinking water because it is considered a consumer beverage.

Standards for Domestic Water with No Fluoride Added

The FDA requires that domestic bottled water with no fluoride added contain between 1.4 and 2.4 milligram per liter (mg/L) of fluoride, depending on the average air temperature where the water is sold for retail.

Added Fluoride

For bottled water with added fluoride, the FDA requires that it contain between 0.8 and 1.7 mg/L fluoride, depending on the average air temperature where it is sold.

Imported Bottled Water

Imported bottled water with no added fluoride may not contain more than 1.4 mg/L of fluoride. Imported water with added fluoride may not contain more than 0.8 mg/L fluoride.

Labels

The FDA does not require that fluoride content be listed on the bottle; but if fluoride is added, it must be listed. To find out the amount of fluoride in bottled water, you would have to contact the manufacturer.

Reasons to Regulate Fluoride

According to the Centers for Disease Control, fluoride tends to reduce the incidence of tooth decay; although a number of factors determine a person's proclivity to get cavities. Consumption of fluoride well above drinking water levels may lead to bone disease or mottled teeth.
