Silver diamine fluoride (SDF) is a minimally invasive, low-cost treatment that dentists paint on the teeth to painlessly treat cavities. SDF was approved by the FDA in 2014. Until now, no option for the treatment of cavities besides restorative dentistry (i.e.fillings) has shown substantial efficacy. Silver diamine fluoride (SDF) is a topical medicament that can be used to treat cavities in the least invasive way possible. The silver acts an an antimicrobial and the fluoride promotes remineralization. Although countries around the world have been using SDF for decades, the FDA recently cleared the product for the U.S. market in 2014. Our doctors would be more than happy to discuss the uses and applications of SDF and to find out if it is an appropriate alternative treatment for your child.
