Which fluoride compound is typically not used in water fluoridation due to its high cost?

In the context of water fluoridation, stannous fluoride is generally considered to have higher production and handling costs compared to other fluoride compounds. It is a form of fluoride that has the added benefit of providing anti-cavity protection while also possessing antibacterial properties. However, these benefits come at a price, which makes it less commonly used for large-scale water fluoridation programs that require cost-effective solutions.

In contrast, other compounds like sodium fluoride or calcium fluoride are typically favored due to their availability and lower costs, making them more practical for widespread use in drinking water systems. Amine fluoride, while also effective, has specific applications and is not as widely used as the more economical alternatives. Therefore, the decision to avoid stannous fluoride in water fluoridation is primarily based on the economic aspect relative to its cost-effectiveness compared to other fluoride options.
