Silver Diamine Fluoride (also known as SDF) is the newest form of fluoride variation. SDF is approved by the FDA for use by pediatric dentists for a kids cavity. It is specifically approved for use by a pediatric dentist as a desensitizer. But that is not what has many dental professionals excited about Silver Diamine Fluoride. Many dentists are using SDF “off-label” to arrest tooth decay and delay treatment for a child’s cavity.
Like other fluorides that have been around longer, Silver Diamine Fluoride will embed its mineral content into the outer layer of enamel. That makes it harder for acid (from foods or bacteria) to dissolve away and weaken the tooth's structure. What makes Silver Diamine Fluoride unique, is that the silver that it contains also has an antibacterial property. In other words, when enamel has been invaded by bacteria, and your pediatric dentist applies SDF, it will “freeze” or “kill” the bacteria. Hence, slowing down (or maybe even arresting) the progression of your child’s cavity.
So once Silver Diamine Fluoride is placed over my child’s cavity, does the cavity have to be fixed?
Yes. The Silver Diamine Fluoride will often (at best) arrest the activity of the bacteria that it comes into contact with. Most children’s cavities can advance well beyond the surface of the tooth. Which means the SDF cannot penetrate deep enough to fully halt the process of the kids cavity.
Also, the Silver makes the cavity dark grey or even black. Most parents will want the unsightly cavity restored esthetically. Last but not least, a cavity by definition is a hole in the tooth. So, even if all the bacteria in that hole can be killed by the silver, food particles and plaque will easily accumulate in the kid's cavity. Restoring the form and function of a SDF treated tooth most often means having your pediatric dentist fill the tooth.
In Short, Silver Diamine Fluoride is a great way to slow down the progression of a child’s early cavities. Although, there will still be the need to restore form and function to the tooth by your pediatric dentist in due time.
Applying SDF is a pretty quick and painless procedure. The majority of dentists follow the recommended steps outlined in the Chairside Guide by the AAPD.
