Which of the following is an advantage of using SDF?

• A. It requires lengthy anesthesia.
• B. It is noninvasive and reduces pain.
• C. It is extremely expensive per application.
• D. It does not restore function.

Answer: (B)

Silver diamine fluoride is valuable because it offers a noninvasive, painless way to halt dental decay without drilling or anesthesia. This makes it especially suitable for kids, patients with limited cooperation, or lesions in hard-to-reach areas where conventional drilling would be difficult or uncomfortable. The application is quick and straightforward, and it can be more cost-effective per visit than performing operative restorations. While it doesn’t restore tooth structure by itself, it stops progression and preserves the tooth so it can remain functional until a definitive restoration is planned.
