Q: What is the recommended level of community water fluoridation?

(A). 0.1 ppm
(B). 0.2 ppm
(C). 0.7 ppm
(D). 2 ppm

Community water fluoridation is the single most effective public health measure for preventing tooth decay. It is very inexpensive ($0.12 to $1.16 per individual/year) and cost-effective. A lifetime of fluoridated water for an individual is less than the cost of one dental filling.

The source of information regarding the level of water fluoridation is the CDC. According to the CDC website and guidelines, the newly recommended level of fluoride is 0.7 ppm.

Answer: B. 0.7 ppm

But wait one second … what about the guidelines that state, “depending on the climate, the recommended fluoride concentration is 0.7-1.2 ppm”? Well, that is the previous guideline, NOT the newest one. If you have read an older edition of the textbook or paper, make sure you tell your friends and faculties about the newest guidelines.

Where can I find the information

If you are in doubt, go to the CDC website, and search “water fluoridation”. You will the most recently updated answer. You can also see the recommendations made by the U.S. Public Health Services about fluoride concentration in drinking water. To add a little more information on this topic, water that has fluoride levels over 2 ppm undergoes defluoridation.
