In communities with a population of over 50,000 people, fluoridation costs were estimated at 31 cents per person per year. The estimated cost rises to $2.12 per person in areas with a population below 10,000.
Fluoridated water creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes, and increases the rate at which it remineralizes in the early stages of cavities. [3] Typically, a fluoridated compound is added to drinking water, a process that in the U.S. costs an average of about $1.32 per person-year.
By comparison, fluoride toothpaste costs an estimated $11–$22 per person-year, with the incremental cost being zero for people who already brush their teeth for other reasons; and dental cleaning and application of fluoride varnish or gel costs an estimated $121 per person-year.

Water fluoridation is the most cost-effective way to induce fluoride, with an estimated cost between US$0.50 and $3.00 per person per year, depending on the size of the community involved. [33] A dollar spent on fluoridating water is estimated to save $7–42 on dental treatment.
Some 53% of these water systems have fluoride concentration within recommended levels - between 0.7mg per liter and 1.2mg per liter. Just under half of them (47%) have fluoride concentration under ...
