Advertising campaigns may have some limited utility, but more directly, there are many locations where the positive aspects of fluoridation are accepted, but rather than medicating the entire water supply for the benefit of a trivial fraction of consumers, fluoride compounds can be added to consumables such as salt (the same way they offer iodized salt for health reasons.)
This way, families with children prone to dental caries can purchase and consume a known dosage of the compound, while not mandating the spending of millions of dollars of the community’s limited resources to dump fluoride onto the lawns, into the sewers, and make one more “contaminant” that industrial consumers must pay to remove in their production processes.
This is not an “Anti-Fluoridation” screed, but a sober, thoughtful response to many in the industry who firmly believe that there are other, more practical ways to provide this benefit to those members of the community who will see an advantage from fluoride compounds, while not forcing everyone to ingest it, whether they want to or not, and to waste a majority of the fluoride added to the water supply which is never consumed by any of the utility’s customers.
