What is claimed is: 1. A method of bonding a dental material to a dental structure, the method comprising: applying a self-etching adhesive composition to a dental structure surface under conditions effective to cause the adhesive to etch the dental structure surface; wherein the self-etching adhesive composition comprises: an ethylenically unsaturated compound with acid functionality; an ethylenically unsaturated compound without acid functionality; an initiator system; and water, wherein the composition is a self-etching, water-in-oil microemulsion; drying the dental structure surface to form a first adhesive layer thereon; optionally applying a second adhesive over the first layer to form a second adhesive layer thereon; applying a dental material to the dental structure surface having the first adhesive layer and optionally the second adhesive layer thereon; and hardening at least one of the adhesive layers under conditions effective to form a bond between the dental material and the dental structure. 2. The method of claim 1 wherein the dental structure surface comprises enamel, dentin, or cementum. 3. The method of claim 1 wherein at least one of the adhesive layers is hardened before, during, or after applying the dental material. 4. The method of claim 1 wherein the second adhesive is the same as the self-etching adhesive composition. 5. The method of claim 1 wherein the second adhesive is different than self-etching adhesive composition. 6. The method of claim 1 wherein the dental material is a dental restorative. 7. The method of claim 1 wherein the dental structure surface is uncut. 8. The method of claim 1 wherein the dental structure surface is unetched prior to applying the self-etching adhesive composition thereto. 9. The method of claim 1 wherein the dental material is a dental restorative. 10. The method of claim 1 wherein the dental material comprises an orthodontic adhesive. 11. The method of claim 1 wherein the dental material comprises an orthodontic appliance. 12. The method of claim 11 wherein the orthodontic appliance is selected from the group consisting of a bracket, a buccal tube, a band, a cleat, a button, a lingual retainer, a lingual bar, a bite blocker, a crown used for connection to a Herbst appliance, an attachment device for use with a tooth positioner, an attachment device for use with a removable appliance, and combinations thereof. 13. The method of claim 11 wherein the orthodontic appliance is precoated with an orthodontic adhesive. 14. A method of adhering an orthodontic appliance to a tooth, the method comprising: applying an adhesive composition to a wet tooth surface under conditions effective to cause the adhesive composition to etch the tooth surface; wherein the adhesive composition comprises: an ethylenically unsaturated compound with acid functionality; an ethylenically unsaturated compound without acid functionality; an initiator system; and water, wherein the composition is a self-etching, water-in-oil microemulsion; applying an orthodontic appliance to the tooth surface having the adhesive composition applied thereon; and hardening the adhesive composition under conditions effective to form a bond between the orthodontic appliance and the tooth. 15. The method of claim 14 wherein the adhesive composition further comprises a surfactant. 16. The method of claim 14 wherein the orthodontic appliance is selected from the group consisting of a bracket, a buccal tube, a band, a cleat, a button, a lingual retainer, a lingual bar, a bite blocker, a crown used for connection to a Herbst appliance, an attachment device for use with a tooth positioner, an attachment device for use with a removable appliance, and combinations thereof. 17. A method of adhering an orthodontic appliance to a tooth, the method comprising: applying an orthodontic appliance having an adhesive composition thereon to a tooth surface under conditions effective to cause the adhesive composition to etch the tooth surface; wherein the adhesive composition comprises: an ethylenically unsaturated compound with acid functionality; an ethylenically unsaturated compound without acid functionality; an initiator system; and water, wherein the composition is a self-etching, water-in-oil microemulsion; and hardening the adhesive composition under conditions effective to form a bond between the orthodontic appliance and the tooth. 18. The method of claim 17 further comprising applying the adhesive composition to an orthodontic appliance to provide the orthodontic appliance having the adhesive composition thereon. 19. The method of claim 17 wherein the orthodontic appliance having the adhesive composition thereon is provided as a precoated orthodontic appliance. 20. The method of claim 17 wherein the orthodontic appliance is selected from the group consisting of a bracket, a buccal tube, a band, a cleat, a button, a lingual retainer, a lingual bar, a bite blocker, a crown used for connection to a Herbst appliance, an attachment device for use with a tooth positioner, an attachment device for use with a removable appliance, and combinations thereof.
