1. A usage indicator for indicating patient compliance, comprising: a dental appliance having, on a surface of the dental appliance, a controlled-release coating that covers an agent that is inactive until it comes in contact with liquid or moisture, wherein: the agent indicates wear in response to the liquid or moisture reacting with the agent; andthe agent is one of: a chemical agent, an electrical agent, an optical agent, or a mechanical agent. 2. The usage indicator of claim 1, wherein the indicator is on a removable appliance, adapted to fit over teeth on a jaw. 3. The usage indicator of claim 1, wherein release of the agent is stimulated by liquid or moisture and wherein, upon wearing the appliance, oral fluids activate the agent and allow the agent to seep out and indicate compliance. 4. The usage indicator of claim 1, wherein one or more oral fluids seep in to activate the agent to indicate compliance. 5. The usage indicator of claim 1, wherein the agent is included in a layer, wherein the layer is formed over at least a portion of the surface of a repositioning appliance. 6. The usage indicator of claim 5, wherein the layer consists essentially of the agent, wherein the agent is attached directly to a surface of a polymer shell of the appliance, which is an elastic repositioning appliance. 7. The usage indicator of claim 5, wherein the layer includes the agent present in or on a carrier or binder which promotes adhesion or attachment to the appliance and/or which creates a matrix from which the agent is released by diffusion or dissolution, wherein the agent is dissolved in the carrier or binder, wherein the agent is provided in powder and dissolved in a liquid solvent, wherein the solution may be applied to a surface of the appliance. 8. A system for monitoring orthodontic treatment comprising: a first appliance for placement over one or more teeth; andmultiple wear indicators including at least a first wear indicator having a wear rate and a second wear indicator having a wear rate, where the wear indicators include a controlled-release coating that covers an agent that is inactive until it comes in contact with liquid or moisture, wherein: the agent indicates wear in response to the liquid or moisture reacting with the agent; andthe agent is one of: a chemical agent, an electrical agent, an optical agent, or a mechanical agent, and where the wear rates of the first and second wear indicators are the same and where the first wear indicator is placed in a position on the first appliance that is different from the second wear indicator. 9. A dental wear indicator, comprising: an adhesive layer;a wear indicator layer having a controlled-release coating that covers an agent that is inactive until it comes in contact with liquid or moisture, wherein the agent indicates wear in response to the liquid or moisture reacting with the agent; anda protective layer. 10. The dental wear indicator of claim 9 wherein the agent is one of: a chemical agent, an electrical agent, an optical agent, or a mechanical agent. 11. The dental wear indicator of claim 9, where the protective layer is removable. 12. The dental wear indicator of claim 9, where the dental wear indicator demonstrates a change in at least one characteristic of the indicator, wherein the changed characteristic comprises at least one of color, shape, deformation, and size. 13. The dental wear indicator of claim 9, where the change is affected by at least one of moisture, temperature, one or more chemicals, or one or more biological substances. 14. The dental wear indicator of claim 9, where the dental wear indicator is adapted to be mounted onto a dental appliance to indicate wear of the dental appliance. 15. The dental wear indicator according to claim 9, wherein the dental wear indicator is adapted to alter the electrical characteristics of an appliance to which it is applied. 16. The dental wear indicator of claim 9, where a type of wear that determines the wear rate of the wear indicator layer is determined based upon one of the factors selected from the group including: an amount of saliva produced;one or more tooth anatomies or locations;a comparison of saliva;an analysis of sleep habits of a patient;an amount of liquid consumption; andone or more types of liquid consumed. 17. A system for monitoring orthodontic treatment, comprising: a first appliance for placement over one or more teeth; andmultiple wear indicators including at least a controlled-release coating that covers an agent that is inactive until it comes in contact with liquid or moisture, a first wear indicator having a wear rate and a second wear indicator having a wear rate, wherein: each wear indicator includes a wear indicator layer having a predetermined wear rate;the agent indicates wear in response to the liquid or moisture reacting with the agent; andthe wear rates of the first and second wear indicators are the same and where the first wear indicator is placed in a position on the first appliance that is different from the second wear indicator. 18. The system of claim 17, where each wear indicator include a wear indicator layer having a predetermined wear rate and a protective layer. 19. The system of claim 17, where each wear indicator includes an adhesive layer and a wear indicator layer having a predetermined wear rate. 20. The system of claim 17, where each wear indicator includes an adhesive layer, a wear indicator layer having a predetermined wear rate, and a protective layer.
