Fluoride varnish preparations contain up to 22,500 ppm fluoride, but only a very small amount is applied (2.3 to 5.0 mg). The resin-based varnish initially sticks to the teeth; then, as the varnish slowly breaks away from the tooth surface, it is ingested over time.

Is silver diamine fluoride the same as fluoride?

SDF received Food and Drug Administration approval in 2014 as a device for treating dental hypersensitivity. Similar to its predecessor fluoride varnish, SDF has not been approved as a dental caries arrest medicament and is administered in children and adults as an off-label use.

If SDF comes into contact with skin, it will cause a small dark spot that will go away on its own in 1-2 weeks. If it comes into contact with existing white fillings, it might stain the margins if they are open. And if a filling is placed the same day, it will probably stain.
