· SnF2

Tin(II) fluoride (SnF₂) is an inorganic ceramic compound composed of tin and fluorine, belonging to the halide ceramic family. It is primarily used in dental care formulations as an active anti-caries and anti-bacterial agent, where it strengthens tooth enamel and inhibits plaque formation; it also appears in limited industrial applications including glass manufacturing and as a precursor in tin compound synthesis. SnF₂ is valued in dentistry for its proven efficacy in cavity prevention and gum health, though it has largely been supplemented by sodium fluoride in some markets due to formulation stability and taste considerations—making it a specialized choice for targeted dental therapeutic applications.
