Dental medicament applicator
A dental medicament applicator is disclosed. In one embodiment, a placement device is sized for insertion at a dental site, such as an interproximal site. The placement device includes a central body and at least one active matrix secured to the central body containing a topical substance, such as a fluoride-containing chemical agent, silver diamine fluoride, or a peptide-based chemical agent, for example. One or two wings extend from the central body to provide subterminal opposition surfaces to hold the placement device during placement. The one or more wings are free of the topical substance. The active matrix, in response to being physically affixed to the dental site, delivers the topical substance at a controlled rate to the dental site while the placement device dissolves at a quicker controlled rate.
