An oral care agent delivery device is provided which comprises a permanently deformable backing layer, an anchor layer overtop the backing layer, and an oral care layer overtop the anchor layer. The device is sized to fit over a plurality of teeth in an upper or lower dental arch of a subject. The oral care layer comprises at least one oral care agent and at least one hydrophilic polymer. The oral care layer is in contact with the anchor layer and forms an adhesive bond with the anchor layer; however, the oral care layer is minimally invested in the anchoring layer. When hydrated, the oral care layer has an adhesiveness relative to the surface of a user's teeth that is sufficient to retain the device on the user's teeth when placed thereon. The device can also have an oral care agent which is activated on hydration of the oral care layer, or an oral care layer which releases the oral care agent over time.

An applicator gun for dispensing hot melt adhesive comprises a hydraulic material supply hose connection, an electrical power cable connection, and a hanger bracket connection. The hose connection may be inverted, and the power cable and hanger bracket connections interchanged so as to provide the applicator gun with different orientation capabilities. The applicator gun may also alternatively accommodate four-finger and two-finger trigger members, and the gun may be connected to the hose connection so as to be movable in alternative modes comprising rotation around a single linear axis or universal movement within six degrees of freedom. The gun also comprises a trigger lock mechanism comprising detent members which provide the operator with tactile indications of the trigger lock mechanism being disposed at LOCKED and UNLOCKED positions, and an enclosed weep hole or window is provided within a side portion of the gun housing so as to alert the operator to hydraulic material leakage prior to the leaking hydraulic material fouling component parts of the gun.
