38% Silver Diamine Fluoride

Silver diamine fluoride (SDF) is a liquid which can be effectively used as a desensitizer. It was cleared as a desensitizing agent by the US Food and Drug Administration in 2014. SDF forms deposits to occlude the dentinal tubules. Fluoride acts as a remineralisation agent to control hypersensitivity by physically sealing exposed dentinal tubules which prevents fluid movement that triggers nerves within the tooth. Fluoride works primarily by precipitating calcium fluoride crystals within the tubules, reducing permeability.
