Silver Diamine Fluoride (SDF)

What Is Silver Diamine Fluoride?

Silver diamine fluoride (SDF) is a liquid medication that’s applied topically to the teeth with a small brush or a special type of floss.

SDF has been used extensively around the world for decades, although it only received approval from the Food and Drug Administration (FDA) in 2014.

The uses of silver fluoride include stopping tooth decay from progressing and keeping the affected teeth stable until a dentist determines if further action is necessary to preserve the health of the teeth. SDF helps harden the tooth structure softened by decay.

SDF works as an alternative cavity treatment by stopping tooth decay from getting worse.
