Abstract
A fluid storage and dispensing container for cleaning teeth, which includes a modified prophy angle headpiece that attaches to existing hand-held prophy cup dental instrument handpieces. The headpiece has an integrated passage through the headpiece by which a fluid is dispensed from the fluid container to the rotatable prophy cup. The headpiece has a lumen through the angle that won't tear or close under flow pressure. The headpiece has a shelf on a top surface for guiding placement of the fluid container, and a snap-fit retaining clip at a base of the headpiece for securing a plurality of different fluid containers. A preferred embodiment of a fluid storage container is a flexible tube that is depressed by a finger or thumb to dispense a fluid such as prophylactic paste or a polishing lubricant to the prophy cup.
