Which of the following is NOT an advantage of SDF?

• A. It is noninvasive and reduces pain.
• B. It is easy to use.
• C. It is inexpensive per application.
• D. Leaves a dark color on treated carious areas.

Answer: (D)

Silver diamine fluoride arrests caries without removing tooth structure, often with little or no discomfort, which makes it noninvasive and painless. It’s quick to apply, so it’s easy to use, and the material itself is inexpensive per application, making it a practical option in many settings. The statement about leaving a dark color on treated carious areas highlights a cosmetic drawback rather than an advantage. That staining can be permanent and esthetically unfavorable, especially on anterior teeth, so it’s not considered an advantage of SDF.
