Silver Diamine Fluoride (SDF) is an FDA-approved topical solution that treats and prevents dental caries and reduces tooth sensitivity. It is made with two acting ingredients: the silver component is an anti-microbial agent that kills bacteria and prevents the formation of new biofilm, and the fluoride prevents further demineralization (softening) of the tooth structure while also helping to remineralize affected tooth structure.
As us about different ways we can use SDF to help prevent the growth of small (incipient) cavities!
