What Is Silver Diamine Fluoride (SDF) for Dental Care?

SDF is a liquid that dentists use to help prevent cavities from growing and spreading. 

This dental treatment can be used on people who don't want to or can’t get traditional restorative treatment, such as children and people with special needs. Typically, it’s used on children aged two to eight. 

SDF is a popular method of treating children’s cavities because:

  • It is inexpensive.
  • It doesn’t require the dentist to actually remove cavities.
  • It can be reapplied after two to four weeks at the back of the mouth
  • It's easy to apply.
