American biochemist Dean Burk, after his retirement, devoted himself to his opposition to water fluoridation. According to Burk "fluoridation is a form of public mass murder."
A 2001 study found that "fluoride, particularly in toothpastes, is a very important preventive agent against dental caries," but added that "additional fluoride to that currently available in toothpaste does not appear to be benefiting the teeth of the majority of people."
The International Chiropractor's Association opposes mass water fluoridation, considering it "possibly harmful and deprivation of the rights of citizens to be free from unwelcome mass medication."
Countless studies have proven fluoridation´s harmful effects are: damaging the IQ, skeletal fluorosis, bone fractures, and, potentially, even cancer.
