Silver Diamine Fluoride (SDF)
Silver Diamine Fluoride (SDF) is a painless, non-invasive, and effective alternative for treating cavities and tooth decay in toddlers and children who don’t have their permanent teeth, yet.
What is Silver Diamine Fluoride?
Silver Diamine Fluoride is a liquid substance used to prevent tooth cavities from forming, growing, or spreading to other teeth. It’s made up of silver, water, fluoride, and ammonia. The silver helps kill any bacteria while the fluoride helps your teeth rebuild the materials they are made of naturally.
Silver Diamine Fluoride is applied directly to the surface of your teeth, most commonly those affected by cavities, but also occasionally used as a preventative measure. Because the fluoride is so effective at reducing cavity growth and requires few treatments it can be used as a great alternative to fillings for younger children and youth who are either restless or don’t yet have permanent teeth.

What is Silver Diamine Fluoride (SDF)?
Silver Diamine Fluoride (SDF) is a FDA-approved liquid solution used in pediatric dentistry to stop active tooth decay without drilling. It combines silver — which kills the bacteria causing the cavity — with fluoride, which strengthens and remineralizes the affected tooth structure. When applied to a cavity, SDF halts the decay process and hardens the softened enamel, all in a quick, painless application.

Who is a good candidate for SDF treatment?
SDF is particularly well-suited for young children with early or active cavities who may have difficulty sitting through a traditional filling, children who need multiple cavities treated in one visit, or patients with significant dental anxiety. It’s also a practical option when a cavity is in a baby tooth that will fall out soon, or when scheduling or circumstances make immediate traditional treatment difficult.
-
Does Silver Diamine Fluoride treatment hurt?
No — SDF treatment is completely painless. There are no needles, no drills, and no removal of tooth structure. We simply dry the tooth and paint the solution directly onto the cavity with a small applicator brush. The entire process takes just a minute or two per tooth.
-
What are the side effects or limitations of SDF?
The primary limitation of SDF is cosmetic: the treated cavity area will permanently turn dark brown or black. This discoloration is confined to the decayed portion of the tooth and does not affect healthy enamel. Because of this, SDF is most commonly recommended for baby teeth or back teeth where appearance is less of a concern. Treated areas may still need a conventional filling or crown at a future appointment to fully restore the tooth’s structure and function.
-
Does SDF treatment replace the need for fillings?
SDF stops active decay from progressing, but it does not restore the shape or function of a tooth the way a filling does. For teeth — especially permanent teeth — that need to be fully restored, a filling or crown will eventually be needed. SDF is best understood as an effective first-line treatment that halts decay, manages discomfort, and gives families more flexibility in when and how they pursue definitive restoration.
