Silver Diamine Fluoride (SDF) is an antimicrobial liquid that is used to treat cavities in a non-invasive, fast, affordable, and painless manner.
What is Silver Diamine Fluoride?
Silver Diamine Fluoride, or SDF, is an FDA-approved antibiotic liquid that, when applied topically, can stop cavities from progressing. While this treatment won’t always prevent the need to fix the cavity in the future, it has been proven effective in stopping further decay until either the baby tooth is lost, or a more permanent means of repair, like a filling or crown, can be performed.
This technique is vey useful in young, fearful or pre-cooperative children and those with special healthcare needs who may otherwise require sedation or general anesthesia for cavity repair.
SDF cannot restore tooth form or function, so it is most beneficial for smaller cavities or as a method to “buy time” until a child can tolerate traditional cavity repair or a baby tooth is lost naturally.
After the treatment area is isolated and dried, the Silver Diamine Fluoride is applied to the cavity using a small brush or special dental floss. Then a fluoride varnish is placed over the Silver Diamine Fluoride so it can work its magic undisturbed.
A follow-up appointment for a second application is needed, preferably within 3-6 weeks. After your child’s procedure, daily home treatment with a fluoride rinse (like ACT) is recommended, as is twice daily brushing with a fluoridated toothpaste.
What to Expect After Treatment
After your child’s appointment, you may notice some discoloration where the SDF made contact with the surrounding tissue of the gum, skin or an existing restoration. The decayed area where the Silver Diamine Fluoride was applied will also turn dark. This is an indication that the SDF is working and is perfectly natural.
Silver Diamine Fluoride is a safe, FDA-approved, effective way to stop decay. However, if your child has a silver sensitivity, please let us know before their appointment.
