Fluoridation of public water supply: bioethical, legal and political approach

Abstract This article aims to analyze the bioethical aspects and legal and political issues of water fluoridation, creating a discussion based on established studies and new research, in order to contribute to an ethical and impartial perspective on the subject. A bibliographic review study was performed, based on a survey of specialized literature on “fluoridation”, “bioethics” and “fluoride poisoning”. Water fluoridation is an important public health measure for the prevention of dental caries, and its efficacy has been demonstrated in several studies. As it is mandatory under Brazilian law, bioethical dilemmas arise due to the absence of individual choice on whether to consume or not consume fluoridated water. There appears to be no solution to this moral dilemma, as even if the measure were free from any risk, its compulsory application would still violate the principle of autonomy.
