Tooth seal
nano Silver Fluoride
In your hands is a year’s worth of dental cavity prophylaxis in nanoparticle form.
About Expiration
After some months (~6 months refrigerated), the components in the seal may break down. At this point, it will go from a thin yellow to dark greenish grey. Always test your seal before using and throw it away if it has gone bad.


Nano Silver Fluoride (NSF)
Nano silver particles have the ability to remineralize enamel, in adult and children’s teeth [yes also “baby teeth” aka “milk teeth”] even at a low concentration. It is bactericidal to a wide range of organisms like Streptococcus mutans, Enterococcus faecalis, and Escherichia coli. It has anti-biofilm properties as well.
HOW?
ANTI-BACTERIAL – Silver ions in solution are toxic to bacterial cells, and are especially effective against acid-producing bacteria, like S. mutans, the bug that causes dental caries (cavities), so it mechanically kills the infection already there.
PREVENTS BIOFILM FORMATION – A two-drop treatment lasts about a year, and during that time prevents new bacteria from colonizing the tooth surface, e.g. prophylaxis against new infections. This preventative strategy does not select for a population, so it doesn’t create drug-resistant bacteria! (phew!)
REMINERALIZATION – Nano Silver Fluoride not only
prevents further decay of the dentin, it can actually help to rebuild and recover from damage that has already occured.
So, how do I use this inexpensive, completely safe, super-effective treatment???
Think of the nanoparticle solution like a shield. Two drops per tooth will create a concentration of silver that adheres to the surface of the tooth and can provide lasting protection for about a year…and is MORE effective at caries prevention than fluoride treatments alone.

Application
For caries treatment, the tooth needs to be isolated from saliva. Clean the area first using a microbrush. Using cotton balls or paper towels, dry the tooth/teeth surface(s) to be treated, and tuck more into the gums above the tooth to keep it dry during the process. No additional effort to remove the caries or unsupported enamel is necessary, NSF has been shown to halt caries formation already in progress.
Once dry, use the cotton balls to hold the cheeks away from the gums and teeth. The selected tooth should received two drops of NSF, which can also applied with a microbrush applicator tip, (equivalent to a dose of 10 mg). If you use a cotton swab to apply, add one drop to accommodate what gets lost in the swab.
The NSF solution should be left in contact with the tooth surface for 2 minutes. (Do not lick your teeth during that time.) If necessary, repeat the process in 12 months.
