“Technical grade fluoridation chemicals are safe and effective”
The level of refinement is also the difference between whether it is pharmaceutical grade or not. In the case of the fluoridation chemicals, they are not as refined as that used in toothpaste, however they have undergone chemical analysis and the amount of impurities are known and listed on the label.
These impurities are in very low quantities and when the fluoridation chemicals are added to water, these impurities dilute to miniscule levels. For instance, many of the impurities will make up less than 10mg of 1kg of the formula. This is diluted down to 1 part per million, meaning that any impurities are diluted down to less than 10 parts per billion.
For more information, look at the page on trace elements.
Have you heard of any other anti-fluoridation arguments that I’ve not covered? Feel free to forward them to me via the post submissions forms here and, time pending, I’ll do what I can to provide a strong counter-argument based upon facts.
