Tin(II) fluoride is widely used in dental care products, especially in toothpaste and mouth rinses, due to its ability to prevent tooth decay. It strengthens tooth enamel by forming a more acid-resistant layer on the surface of teeth, helping to reduce cavities. It also has antibacterial properties that inhibit the growth of plaque-causing bacteria in the mouth. Unlike some other fluoride compounds, tin(II) fluoride provides both anti-caries and anti-sensitivity benefits, making it effective for people with sensitive teeth. It is particularly valued in formulations designed for long-term oral health protection and is often included in products aimed at reducing gingivitis and bad breath.
