Silver Diamine Fluoride (SDF) Treatment
What Is SDF?
Silver Diamine Fluoride (SDF) is a safe, topical liquid used to slow or stop the progression of tooth decay. It combines the antibacterial power of silver with the remineralizing benefits of fluoride, making it a helpful option for managing cavities, especially in very young children or patients who are not yet ready for dental fillings.
A gentle, non-invasive way to slow down tooth decay.
When Is SDF Recommended?
SDF may be recommended for children who:
- Have small cavities in baby teeth
- Are not yet able to tolerate dental drilling or restorative procedures
- Have special healthcare needs
- Need a temporary cavity management option before further treatment
It is often used to buy time until a child is ready for more comprehensive dental care or when we want to avoid sedation or local anesthesia.
How Does the Process Work?
The SDF treatment is quick, painless, and non-invasive:
The entire process takes only a few minutes and does not require numbing.
What Are the Benefits of SDF?
- Non-invasive and needle-free
- Quick and easy to apply
- Helps prevent decay from progressing
- Can delay or reduce the need for sedation or restorations
- Well tolerated even by very young or anxious children
Things Parents Should Know
- SDF will turn the decayed area of the tooth dark brown or black. This staining is a sign that the decay has been stopped, but it is permanent on the treated area.
- Healthy parts of the tooth remain unchanged in color.
- SDF does not restore the shape or function of the tooth like a filling would; it is meant for cavity control, not cosmetic repair.
- We may recommend monitoring the tooth or following up with a full restoration later.
Frequently Asked Questions
Is SDF safe for my child?
Yes. SDF is approved by the FDA and has been used worldwide for many years. It is especially helpful for young children or those with special needs who may not tolerate traditional treatment.
Will it hurt?
Not at all. The procedure is painless and doesn’t require shots, drilling, or sedation.
Why does the tooth turn black?
This is a normal and expected effect of SDF. The dark staining shows where decay has been arrested. We will discuss the esthetic outcome with you in advance.
Can SDF be used on permanent teeth?
In some cases, yes—such as to manage early decay or when traditional care is not yet possible. However, it is more commonly used for baby teeth.
Is this a permanent solution?
SDF is a great tool for slowing down decay, but it is not always a final treatment. We may recommend follow-up care such as a filling or crown when your child is ready.
