Silver Diamine Fluoride (SDF)

Finally an Alternative to Drilling and Filling

What is SDF?

Silver Diamine Fluoride (SDF) is a clear, odorless, non-toxic liquid that is used to arrest tooth decay in children and adults. It is the only treatment in the history of oral health to be granted the "Breakthrough Therapy Designation" by the U.S. Food and Drug Administration (FDA), and contains a water-based solution composed of silver, fluoride and ammonia.

How is it used?

SDF can help stop cavities from getting worse, which will delay or prevent the need for more invasive treatments such as fillings, crowns, or extractions. It is also used to treat tooth sensitivity, especially in areas with gum recession.

What is the procedure?

SDF is applied to a clean, dry tooth by using either a small brush or using special woven floss. The liquid is allowed to dry for 1 minute. There are no postoperative limitations. You may eat, drink, and resume normal dental care immediately.

What are the benefits?

SDF is a fast, low-cost, no-needle, no-drill alternative to treating cavities. SDF can also be used to treat sensitivity.

What are the drawbacks?

SDF permanently stains tooth cavities black, however, the dark spots can eventually be covered with tooth-colored material. SDF does not stain sound tooth enamel or sound dentin. SDF can also temporarily stain skin or gums that come in contact with SDF during the procedure; this temporary staining can last anywhere from 3 days to 3 weeks. Also, SDF will need to be reapplied periodically to keep the cavity arrested.

Is it safe?

There are no known side-effects other than cavity staining. SDF has been used in other countries for more than 80 years without a single adverse event reported. It was approved for use in the U.S. in 2014.

How does it work?

SDF penetrates cavities and both kills pathogenic organisms and hardens softer dentin, making it more acid- and abrasion-resistant.

More about Silver Diamine Fluoride (SDF)
From the American Dental Association:

"Silver diamine fluoride (SDF) may be used in some cases to stop decay when a cavity has formed. With SDF, the dentist applies it directly to the area of decay without first having to drill the tooth.

SDF Application SDF Treatment over time

SDF is an inexpensive option that is simple to apply; however, although it stops the decay from progressing, it does not fill the cavity, and the tooth structure will remain weak if not restored with a filling or crown. Another drawback of SDF is that the color of the treated area will become black. This may be less of a problem in primary teeth, which will be lost as the child ages, than for permanent teeth. Even so, because applying SDF is quick, it may be especially helpful for patients who have trouble sitting still during dental treatments. SDF needs to be reapplied twice a year."

From PBS News Hour:

"There's long been a big push to promote better dental health through fluoridation and telling people to eat less sugary foods.

PBS News Hour

Despite those efforts, tooth decay remains a major public health issue. In fact, it's the most common chronic childhood disease, and 90 percent of all adults have cavities.

As many of us know, traditional treatments can often be painful, but a new pain-free, low-cost dental treatment could help all that."
