Which statement best describes the effect of silver diamine fluoride on caries?

• A. Arrests the caries process.
• B. Completely eradicates all bacteria.
• C. Heals nerve tissue instantly.
• D. Remineralizes all enamel instantly

Answer: (A)

The effect of silver diamine fluoride on caries is to arrest the caries process. When applied, silver ions act as strong antimicrobials, disrupting the bacteria in the decayed dentin and reducing acid production, while fluoride supports remineralization of demineralized tissue. This combination helps form a hard, sclerotic layer that stops further progression of the lesion. It does not instantly heal nerve tissue, and it does not instantly remineralize enamel or completely eradicate all bacteria; the primary clinical outcome is halted decay with a darkened, arrested lesion rather than a return to sound tissue.
