a whitening agent in one of said barrels, said whitening agent containing a peroxide,
an energizer in another of said barrels, said energizer containing a compound of iodine,
plungers in each of said barrels,
exit orifices for each of said barrels that pass through a switch pedestal and through which bleaching components may exit,
a rotabably openable and closeable switch located adjacent said barrels on the switch pedestal, said switch having one half
of a luer-type connector and two conduits that selectively will allow the whitening agent and the energizer to pass through
the switch;
a mixing tip, having an exit orifice on one end and a mating half of a luer-type connector on another end, said tip and said
switch capable of joining with the luer-type connector halves;
said tip having a conduit in it through which bleaching components may travel and a mixing chamber located within said tip
for mixing said whitening agent and said energizer as they pass through the switch conduits in order to form a mixed dental
bleach leaving said switch-closeable double barrel syringe,
said barrel exit orifices lining up with said tip conduits when said tip is in an open position, and
said barrel exit orifices not lining up with said tip conduits when said tip is in a closed position.
