摘要：
A tray appliance of the present disclosure has a first dissolvable sheet and a first substance formed within a second dissolvable sheet. The first dissolvable sheet is laid on the second dissolvable sheet and is formed into a first dissolvable negative impression of a person's teeth, gingival tissue, or other soft tissue, such that when first dissolvable negative impression is worn by a person, the first dissolvable negative impression dissolves and releases the first substance into the person's saliva, teeth, gingival tissue, or other soft tissue.
