What is the role of silver diamine fluoride in managing dental caries?

• A. Stains teeth
• B. Has no effect
• C. It is an antiseptic that can be used as substitute for mechanical cleaning
• D. Arrests lesions

Answer: (D)

The main idea is that silver diamine fluoride arrests caries by stopping progression through both antimicrobial action and remineralization support. Silver ions disrupt the bacteria in the carious lesion, reducing progression, while fluoride helps remineralize demineralized dentin. This combination allows an active lesion to become arrested, meaning further decay slows or stops. It’s especially useful when a quick, minimally invasive approach is needed or when conventional drilling isn’t feasible. Aesthetic trade-off is that the treated carious tissue often stains darkly, which is a consideration for planning. It’s not a substitute for mechanical cleaning when that is possible, but it provides a practical means to halt lesions and stabilize the situation.
