Heard About SDF? Now Here’s the Truth

Silver diamine fluoride (abbreviated as “SDF”) has, for a little over the past year, been touted as a miracle cure for cavities.

But is it, though?

Benefits of Silver Diamine Fluoride

SDF has been approved by the FDA for use in treating extremely sensitive teeth. It’s also shown to have properties that stop bacteria in cavities, so some dentists use it off-label as an early treatment for tooth decay.

A Few Disclaimers

There are a few downsides/precautions to using SDF:

  • Although a clear fluid, SDF can stain clothes and skin
  • It takes at least two applications (a week apart) to get the anti-cavity effect
  • It tastes terrible (we’re just being honest!)
  • It will stain the decay black, not turn it white like the rest of tooth
  • Other teeth may get stained in the process
  • You can’t use SDF if you’re allergic to silver

SDF or a Filling?

At this point, not even SDF can completely replace the role that today’s fillings play.

If you have just a spot of decay, treating it a couple times with SDF may stop the infection from progressing. To restore lost tooth structure, however, you’d still have to get a dental filling.

Baby teeth should not be allowed to decay away, since cavities cause pain and even damage to adult teeth. But some children don’t handle major dental treatment very well. The same can be said of some elderly individuals with cavities on tooth roots.

SDF can make it easier to stop dangerous cavities in their tracks and prevent certain individuals from needing fillings.

To find out more about SDF and its dental applications in your area, contact your local family dentist.
