Silver Diamine Fluoride is composed of two primary components: silver and fluoride. Silver acts as an anti-microbial agent that simultaneously strengthens the underlying protective layer of your teeth called dentin. Fluoride is the active ingredient that puts a stop to tooth decay and helps prevent additional decay from appearing. During your visit, it will be applied with a microbrush after your teeth are cleaned of debris and prepared for the treatment. Once the tooth has been treated, we advise our patients not to eat or drink or at least an hour to allow it to cure.
