Dentists: what kind of glue do cosmetic dentists use for gluing porcelain veneers?

Cement: There are a number of different cements available to the profession to cement veneers. These cements have the property, together with the associated adhesives, to bond to tooth structure and porcelain after they have been properly etched and cleaned. They are usually dual cured and need to be applied in a totally dry environment. Hope this info helps..

Luting composite: that is light cured, has a matching try-in gel, cleans up easily and has excellent physical properties. RelyX Veneer Cement is a good example.
