What Is Silver Diamine Fluoride (SDF)?

Silver Diamine Fluoride, or SDF, is a colorless liquid that dentists apply to the teeth using a small brush to prevent, slow down, or stop tooth decay. The use of SDF prevents the need for extensive dental treatments like root canals, dental fillings, and tooth extraction.

What Is the Silver Diamine Fluoride Process?

Examination and Preparation

The dentist first checks the condition of the teeth to determine whether SDF is an appropriate treatment. If so, they’ll clean the teeth thoroughly with a brush and scraping tools to remove plaque and bacteria from the teeth. Doing so gives them a clean slate for applying the liquid solution.

The next step involves applying the Silver Diamine Fluoride liquid using an applicator or small soft brush. Our pediatric dentist carefully applies the liquid on the surface of the teeth with decay or signs of dental decay. This only takes a minute or two to complete.


The dentist will leave the tooth to dry for a couple of minutes. This drying allows the silver ions in the liquid solution to penetrate the infected area of the teeth and kill cavity-causing bacteria. This stops and prevents further dental decay for three to twelve months before you can get a follow-up application.

Rinsing and Applying Varnish

The dentist will rinse the teeth to remove any excess SDF. Some patients may require the application of fluoride varnish to strengthen the teeth and increase the effectiveness of SDF against dental decay.  The dentist might also apply a glass ionomer or resin-based coating for further protection.

What Are the Benefits of SDF?

SDF is immensely beneficial for patients of all ages. First, the liquid is highly effective against cavities, helping stop the spread and preventing further SDF. SDF is also a non-invasive method for treating dental decay that doesn’t require the removal of the decayed portion of the teeth. It’s also an inexpensive treatment option for dental decay and prevents the need for more expensive treatments like root canals and tooth extractions.

How Long Does SDF Last on Teeth?

SDF will last for between 3 to 12 months before it requires re-application. However, dentists typically schedule re-application four weeks after the first application. This enhances the effectiveness of the SDF and extends its longevity.

Can I Get SDF Treatment with Braces?

Yes, you can get SDF treatment with braces, regardless of how long you’ve had them. Most dentists recommend SDF treatment with braces because having braces makes it more difficult to maintain proper oral hygiene.
