Let’s Talk Silver Diamine Fluoride or SDF

October 10, 2019
Posted By: Kaitlin Haag

Silver diamine fluoride (SDF) is a minimally invasive way to treat cavities and is easily the biggest innovation for pediatric dentistry in the US in decades. It’s been used in other countries in Europe, Japan, Australia, etc., for a long time. The FDA approved it for use in 2014, and it became commercially available in 2015. SDF is a new treatment option for the medical management of cavities.

Cavities are caused by bacteria (S. mutans) in the mouth. The bacteria feed on simple carbohydrates and release acids that eat away at teeth. Brushing and flossing help clean away the bacteria and prevent them from causing decay to your teeth. Silver diamine fluoride can stop current decay, harden the soft areas of the tooth, desensitize the tooth, and help prevent further decay.

Traditionally, when a dentist finds a cavity, they treat it surgically by placing a filling. SDF is a new way of treating these cavities medicinally AND in a minimally invasive way. The American Dental Association now says that non-restorative treatment options for cavities are the standard of care.




Pros of SDF:

Easy, painless, and fast
No need for local anesthetic (shots)
Very safe→ very low toxicity
Desensitizes teeth
Stops cavities from progressing and prevents future cavities from forming
Alternative to sedations or general anesthesia


Metallic taste
May require multiple applications
Permanently stains the decayed part of the tooth black
May require a traditional filling or a SMART filling to restore the form and function of a tooth or to cover the black staining
Cannot be used if there is an infection in the nerve of the tooth


While I love using SDF, it is not a “silver bullet” for every cavity and every tooth. Please call me and ask for a consultation. I would love to evaluate your child and see if he/she is a good candidate for this exciting and innovative alternative to traditional dental treatment.
