Tin(II) fluoride is widely used in dental care products, especially in toothpastes and mouth rinses, due to its ability to prevent tooth decay and strengthen enamel. It works by promoting the remineralization of early dental caries and reducing the solubility of tooth enamel in acidic environments. It also exhibits antibacterial properties that help control plaque-forming bacteria in the mouth. In addition to its role in oral hygiene, tin(II) fluoride has been used in industrial applications such as a catalyst in certain chemical reactions and as a stabilizer in some polymer systems. Its reducing properties make it useful in specific electroplating and metallurgical processes where controlled reduction is required.
