Abstract
Silver diamine fluoride (SDF) is a colourless and odourless combination of silver and fluoride solution with caries arresting properties. Clinical and in-vitro trials have proven its preventive efficacy for caries in high-risk individuals, which is considered a minimally invasive approach for arresting caries progression in cavitated teeth. This chapter gives an overview of the rationale of caries management by SDF, the mechanism of action, and the current evidence for its effectiveness as an anti-caries agent. The safety of SDF use in humans and its various limitations are also explained in the chapter.
