A device for the treatment of periodontal disease includes a handle that has a configuration familiar to dental professionals, and a cartridge, that is locked into the handle when use, typically delivery of a composition to a periodontal pocket is desired. The cartridge provides for effective delivery of compositions, such as agents, as its tip is deformable, typically from a circular to an oval shape so as to flatten.
