1. An appliance for intraoral delivery of an agent, the appliance comprising:
a shell comprising an inner surface and an outer surface, wherein the inner surface defines a plurality of tooth-receiving cavities configured to apply a repositioning force to a patient's teeth, and the outer surface is oriented away from the patient's teeth;
a reservoir integrally formed in the outer surface of the shell, wherein the reservoir is configured to store at least one agent; and
a membrane covering at least a portion of the reservoir to control release of the at least one agent into an intraoral cavity of the patient, wherein the membrane comprises a plurality of pores that are configured to open based at least in part on a temperature of the patient's intraoral cavity to allow the at least one agent to pass therethrough.
