SDF is a liquid we paint onto a cavity that stops the decay from growing. No drilling. No numbing. No shots. For some kids, it’s the right tool. For others, a traditional filling is the better call. Here’s how to think about it.
Two ingredients. Silver kills the bacteria that cause cavities. Fluoride helps remineralize the tooth surface. Together they stop the cavity from getting bigger. Application takes about a minute per tooth.
Here’s the catch. SDF turns the cavity area dark gray or black. That’s the silver doing its job, but it stays. Some parents are fine with this on a back tooth. Some aren’t, especially on front teeth. We talk through the tradeoff with you before we apply anything.
AAPD recognizes SDF as a non-restorative caries-arrest treatment. It’s been used safely for years across pediatric focused practices in the U.S. and longer than that internationally.
SDF stops the decay. It doesn’t fill the hole. If a tooth has structural damage that needs a filling or crown, SDF isn’t a substitute. We’ll be straight about which situation you’re in.
