If all this is true, how can all this be possible, sanctioned by government?
In 1939 a dentist named H. Trendley Dean, DDS, examined water from 345 communities in Texas. Dr. Dean worked for the U.S Public Health Service (PHS). He determined that high concentrations of fluoride in the water corresponded to a high incidence in mottled teeth. To many dentists this provided an answer to the problem of mottled teeth they saw in some of their patients. Dr. Dean also unexpectedly found a lower incidence of dental cavities in communities having about 1 ppm fluoride in the water supply. Among the native residents of these areas about ten percent developed the very mildest forms of mottled enamel, usually described as "beautiful white teeth". However, Dean used a technique known as "selective use of data", using data from 21 cities while completely disregarding data from 272 other locations, which show an almost complete lack of correlation when plotted.

Meanwhile, a number of court cases were being launched due to fluoride contamination, mainly by the aluminum industry. In addition the Manhattan Project, the secret atomic bomb project, was in a big race to build the world's first A-bomb. A pollution incident of great magnitude occurred at a factory in New Jersey (DuPont) producing millions of tons of fluoride for the project. A major "negative PR" problem was emerging, threatening the Manhattan Project and the secrecy around it.
In 1945, supposedly as a result of Dr. Dean's discovery, the PHS planned to conduct a 10-year study of fluoridation in two cities. Grand Rapids, Michigan was chosen as the city for artificial fluoridation and Muskegon, Michigan was the non-fluoridated city for comparison and cavity rates were to be compared. In 1950, after only five years into the project, due again to pressure exerted from the atomic bomb program, public health officials started to campaign for fluoridation. The campaign was based on the fact that fluoridated Grand Rapids had shown some decrease in cavity rate. Meanwhile there was also a decrease in cavity rate shown in non-fluoridated Muskegon. However, Muskegon was dropped from the study for unknown reasons. After the project was completed, only the Grand Rapids result was released and a major PR campaign promoting fluoride use started.
