Silver Diamine Fluoride (SDF) for Children
Silver diamine fluoride (SDF) is a minimally invasive treatment that can help slow or stop cavity progression in certain situations. It may be recommended for young children, patients with early cavities, or children who may benefit from delaying more extensive treatment. Our team carefully evaluates whether SDF is an appropriate option for each child's individual needs.
What Is Silver Diamine Fluoride?
Silver diamine fluoride (SDF) is a liquid treatment used to help slow or stop cavity progression in certain situations.
When Is SDF Recommended?
SDF may be considered for young children, early cavities, patients with special healthcare needs, or situations where delaying more extensive treatment may be beneficial. It doesn’t make cavities go away, but it can be a great holdover for children who are otherwise unable to sit comfortably or safely for a filling.
How Does SDF Work?
The silver component helps reduce bacteria, while fluoride strengthens tooth structure. Together, they help slow cavity progression. SDF generally takes about 1 minute per cavity to apply with a small brush. The tooth is kept dry with cotton while applying SDF to prevent dilution, which would reduce the efficacy of the treatment.
Advantages and Limitations of SDF
While SDF can be highly effective in certain situations, it is not appropriate for every cavity. It is most effective on smaller cavities and chewing surface cavities, and less effective as a standalone treatment on larger cavities or on cavities between teeth. It may cause treated decay to appear dark in color, but often this area is already discolored, and even if not, usually a dark healthy spot is preferred over an area of decay and infected tooth structure.
Why Baby Teeth Still Matter
Even though baby teeth eventually fall out, maintaining their health supports proper chewing, speech, and development.
