Silver diammine fluoride, (SDF) is a topical medicament used to treat and prevent dental caries  and relieve dentinal hypersensitivity. It is a colorless or blue-tinted, odourless liquid composed of silver, ammonium and fluoride ions at a pH of 10.4 . Ammonia compounds reduce the oxidative potential of SDF, increase its stability and helps to maintain a constant concentration over a period of time, rendering it safe for use in the mouth.Silver  and Flouride ions possess antimicrobial properties and are used in the remineralization of enamel  and dentin on teeth for preventing and arresting dental caries.
