Abstract
A molded, one-piece plastic dental treatment tray for applying fluoride or other medication to a patient's teeth. The tray has a pair of elongated locking flanges on one of its handles which engage the lateral edges of the other of its handles to hold the tray folded up with its two teeth receiving troughs in an aligned, assembled relationship. At least one of the handles is molded at an angle with respect to the bottom of its trough to help ensure that when the tray is folded up, the free ends of its troughs are urged into contact with each other, to enable the tray to be inserted more easily into the patient's mouth. The bottoms of the troughs are flat and smooth enough for them to move easily over each other in any direction while in the patient's mouth, so the tray will better accommodate any individual differences in the mouth, jaws or teeth of the particular patient.
