OPPS!   In a 1972,  report by the  "ADA" 
American Dental Association, it is stated that dentists make 17% more profit in fluoridated areas
as opposed to non-fluoridated areas.  (Douglas et al., "Impact of water fluoridation on dental practices and dental manpower", Journal of the American Dental Association; 84:355-67, 1972) JADA

This was again demonstrated in a 1994/1995 survey by the California Department of Health Services, Medical Statistics, who found a 5% increase.

And then A Dentist discovered this:

DENTAL ASSOCIATION PR LIE REVEALED BY A DENTIST

THE LIE: August 1, 1979: A letter from the Secretary of the Victorian Branch of the Australian Dental Association stated, "In a community with a fluoridated water supply, the dental manpower required to maintain a good standard of dental health in a community is always halved."

 

THE TRUTH: The 1976 edition of the C.B.S. News Almanac published figures showing the number of dentists per 100,000 population in 30 "Representative American Cities."
 
Of these 30 cities, 16 were artificially fluoridated.

 A simple comparison of the fluoridated vs. non-fluoridated cities shows that there were an average of 76.7 dentists per 100,000 population in the fluoridated cities, vs. 59.2 dentists per 100,000 in the non-fluoridated cities.

Furthermore, data from the 1971 American Dental Directory,

 the 1971 U.S. Statistical Abstracts

and the 1973 World Almanac

Reveals that the three American cities which have been fluoridated the longest

(Grand Rapids, Newburgh, and Evanston) averaged 121 dentists

 per 100,000 population, or over twice the national average, after

 approximately 25 years on fluoridated water.
