Silver Diamine Fluoride (SDF)

Silver diamine fluoride (SDF) is a liquid substance used to help prevent tooth cavities (or caries) from forming, growing, or spreading to other teeth.

SDF is made of:

  • SILVER – helps kill bacteria
  • WATER – provides a liquid base for the mixture
  • FLUORIDE – helps your teeth rebuild the materials they’re made of (known as remineralization)
  • AMMONIA – helps the solution remain concentrated so that it’s maximally effective against cavity resonance

SDF was first approved for use in Japan more than 80 years ago. SDF was approved by the U.S. Food and Drug Administration (FDA) in 2014 for use in the United States.

How is it used?


A liquid form of SDF is applied topically, meaning that it’s applied directly to the surface of your teeth using the following steps:

  1. Cotton or gauze is placed near the affected teeth to prevent saliva from moistening the teeth.
  2. Moisture is removed from the surface of the teeth using a vacuum suction tool.
  3. SDF is applied to the area affected by a cavity.


SDF is most commonly used on areas affected by cavities. Research shows that SDF can be just as helpful when used as a preventive measure by being applied to healthy tooth surfaces.


Research also suggests that dentists don’t need to treat cavities with fillings or tooth surface modification before using SDF.

Traditionally, many dentists have used a fluoride varnish to help stop cavity development. SDF has proven to be much more successful at reducing cavity growth than varnish. SDF also requires fewer treatments over time.

There’s no set number of applications required for SDF to work. Most dentists only apply SDF once per year. Varnishes often need to be applied four or more times per year.

I had a long overdue deep cleaning, root canal/crown, AND fillings within a month. Dr. Thurman, Morgan, Kathy and staff were very attentive and kind with not ONLY the procedures and explanations but with checking up on me after the root canal. Also great at helping me figure out my insurance coverage and payments. Dental Elements is GREAT.
