1. A method for forming ornamental indicia carrier for durably adhering to a dental appliance, the method comprising:
forming a first adhesive layer comprising a pressure sensitive adhesive layer configured to be adhered to a polymeric shell of the dental appliance and having a plurality of tooth-receiving cavities shaped to receive and resiliently reposition a subject's teeth from a first arrangement toward a second arrangement;
coupling a first removable protective layer over the pressure sensitive adhesive layer;
applying a second adhesive layer over the first adhesive layer;
coupling a second removable protective layer over the second adhesive layer; and
encapsulating a colorant forming an image between the first adhesive layer and the pressure sensitive adhesive layer of the second adhesive layer.
