What is Silver Diamine Fluoride?
Silver diamine fluoride (SDF) is a clear blue liquid that is brushed on decayed teeth to stop cavities and decrease sensitivity. We do not need to numb teeth to use SDF. Using SDF can sometimes allow us to delay drilling or extracting teeth if the teeth are not hurting or abscessed.
This treatment is often the best option for very young patients who cannot cooperate yet, patients with intellectual or developmental disabilities or even elderly patients. In most cases, these types of patients would have needed to be placed under general anesthesia in order to gain cooperation.
After SDF treatment, we often can fill the areas where the decay has been stopped using a white filling material to cover up the dark SDF stain.
SDF stains decay black and temporarily stains gums and lips a dark brown. It does not stain healthy enamel. It also stains clothing, floors and furniture. Patients report that it sometimes has a metallic taste.
