Silver Diamine Fluoride (SDF) is an FDA-approved topical solution that treats and prevents dental caries and reduces tooth sensitivity. It is made with two acting ingredients: the silver component is an anti-microbial agent that kills bacteria and prevents the formation of new biofilm, and the fluoride prevents further demineralization (softening) of the tooth structure.
Treatment with SDF does not eliminate the need for restorative dentistry (fillings, crowns, etc.) to repair function or aesthetics, but it can be effective at preventing the growth of the cavity. Dr. Greenhill and Dr. Jennison use SDF as a tool to help defer care until your child is older and more cooperative for treatment, or until the tooth falls out.
SDF-treated lesions with temporary gingival staining
Primary teeth with carious lesions
SDF is a simple and noninvasive way to treat carious lesions (cavities), and it can be done from the comfort of our dental office.
- The teeth are brushed without paste and rinsed.
- The carious teeth are isolated, kept dry, and all excess debris is removed.
- A microbrush is dipped in a drop of SDF and placed on the lesion(s) for two minutes.
- Any decayed areas will stain black. Healthy tooth structure will not stain.
- Excess SDF is removed and patients are instructed to not eat or drink for one hour.
Why use SDF?
We recommend using SDF in several situations, including:
- Children who have extreme decay (severe early childhood caries)
- Young children who have difficulty sitting still for treatment
- Special needs patients
- Children with carious lesions (cavities) that need to be treated over several visits
The Advantages of SDF:
- Provides immediate relief from tooth hypersensitivity
- Kills the organisms that cause cavities
- Hardens softened dentin making it more acid- and abrasion-resistant
- Does not stain healthy dentin or enamel
