ABSTRACT:
A dental agent applicator has a barrel, a sealing plug, a delivery head and a plunger. The barrel has a proximal end, a distal end and a chamber defined through the barrel. The sealing plug is mounted in the chamber and hermetically obstructs the chamber. The delivery head is movably mounted on the distal end of the barrel and has a hub and a nozzle tip. The hub is mounted movably in the distal end and selectively moves the sealing plug to make the chamber communicate with the delivery head. The nozzle tip is mounted on the hub. The plunger is mounted slidably in the proximal end of the barrel. The delivery head is mounted permanently on the barrel. Using the dental agent applicator without having to replace any sealing cap with the delivery head is simple and convenient.
