1. A method of bonding a dental material to a dental structure, the method comprising: wetting a surface of a dental structure with a liquid comprising an acid-sensitive dye and water;applying a self-etching adhesive to at least a portion of the wet dental structure surface under conditions effective to cause a visually observable color change before hardening in the portion of the dental structure surface having the self-etching adhesive applied thereon;drying the dental structure surface to form an adhesive layer thereon;applying a dental material to the dental structure surface having the adhesive layer; andhardening at least one of the adhesive layer under conditions effective to form a bond between the dental material and the dental structure. 2. The method of claim 1 wherein the adhesive is hardened under conditions effective to form a bond between the dental material and the dental structure of at least 7 MPa. 3. The method of claim 1 wherein the adhesive is hardened before, during, or after applying the dental material. 4. The method of claim 1 wherein the dental material comprises a dental restorative, an orthodontic adhesive, an orthodontic appliance, or a combination thereof. 5. The method of claim 1 wherein conditions effective to cause a visually observable color change do not comprise exposure to a curing light. 6. A method of restoring a dental structure, the method comprising: wetting a surface of a dental structure with a liquid comprising an acid-sensitive dye and water;applying a self-adhesive composition to at least a portion of the wet dental structure surface under conditions effective to cause a visually observable color change before hardening in the portion of the dental structure surface having the self-adhesive composition applied thereon; andhardening the self-adhesive composition under conditions effective to form a bond between the hardened composition and the dental structure of at least 7 MPa. 7. The method of claim 6 wherein the self-adhesive composition comprises at least 40% by weight filler. 8. The method of claim 6 wherein conditions effective to cause a visually observable color change do not comprise exposure to a curing light. 9. A method of adhering an orthodontic appliance to a tooth, the method comprising: wetting a surface of a tooth with a liquid comprising an acid-sensitive dye and water;applying a self-adhesive composition to at least a portion of the wet tooth surface under conditions effective to cause a visually observable color change before hardening in the portion of the tooth surface having the self-adhesive composition applied thereon;applying an orthodontic appliance to the tooth surface having the self-adhesive composition applied thereon; andhardening the self-adhesive composition under conditions effective to form a bond between the orthodontic appliance and the tooth. 10.
