Skin and soft tissue will discolor within minutes to hours after contact and fade away (via surface shedding) within a few days. Dentin and enamel with no demineralization present will receive surface (pellicle) stains that can be removed with pumice, while demineralized tooth structure will stain more permanently black. A mild but transient increase in erythema in the gingiva near the tooth treated by silver diamine may occur[17].
