Normally, the content of fluoride in surface and ground water is lower than 1 mg/L. Permanent consumption of water containing more than 2 mg/L fluoride can cause a drinking water fluorese (a stained discolouration of the tooth enamel). On the other hand a content of fluoride lower than 0,5 mg/L could lead to an increasing risk of caries. The optimal content of fluoride in drinking water is about 1 mg/L. To avoid problems with caries in some countries the content of fluoride in drinking water is artificially increased. However, WHO and EC drinking water regulations recommend a threshold value of 1,5 mg/L F⁻.

In some European countries, the threshold value for mineral water is also 1,5 mg/L F⁻. For the suitability of water for the preparation of baby food a threshold value of 0,7 mg/L F⁻ is recommended. Natural mineral waters with a fluoride content of more than 5 mg/L must be labelled with a warning.
