Abstract: A disposable dental tray includes a disposable tray body defining four utility compartments. Three of the utility compartments are disposed along a first side of the tray body, the fourth utility compartment being disposed along a second side of the tray body. All four of the utility compartments have relatively flat bases and are defined by integrally formed ridges extending upwardly from the compartment bases. Each compartment is surrounded by a defining ridge, interior defining ridges being offset from each other so that no interior ridge extends completely across the tray. The tray body further includes an instrument compartment defined by an encircling ridge extending upwardly from the base of the instrument compartment. The instrument compartment has integrally formed therein a series of grooves for holding dental instruments, which grooves are elevated above the base of the instrument compartment.
