Page "Water fluoridation controversy" Paragraph 13

In 1986 fluoridation opponent Mark Diesendorf pointed out the substantial declines in tooth decay in nonfluoridated European countries.

This failed to account for the fluoride added to table salt in continental Europe.

Although fluoridation may still be a relevant public health measure among the poor and disadvantaged, it may be unnecessary for preventing tooth decay, particularly in industrialized countries where tooth decay is rare.
