ABSTRACT:
A dental tray of the present invention includes a body made from a generally fluid impervious material (preferably a closed cell foam) having a bottom and side walls to define an arched channel sized and shaped to fit over a patient's teeth. A deformable, arched gasket is fixed to the body along an upper edge of the body wall. The gasket extends inwardly from the tray body wall and defines an arched slot. The gasket inner edge contacts and seals against the patient's gums and teeth when the tray is applied to the patient's teeth to substantially prevent compounds from leaking from the sides or back of the tray during use of the tray. Preferably, two identical trays are connected together by a connector. The connector is adhered to the base of the trays, generally at a front of the trays. The connector is folded over upon itself when the two trays are inserted in a patient's mouth and define a handle. The handle extends through the patient's lips from a position generally between the patient's teeth. The trays may be pre-filled with the compound or medicament to be applied to the patient's teeth. If so, the tray is sealed to prevent loss of the compound or medicament during transportation and storage of the trays. The trays are also individually wrapped.
