They are attached to the tooth with a special dental adhesive. In order to create enough space for the veneer, the affected tooth is lightly reduced beforehand. In certain cases it is even possible to apply the veneer directly to the tooth – without preparation (e.g. with Lumineers®).
Veneers are generally not used in children. For ceramic shells, teeth must have “outgrown” completely and a tooth position and gum line must have been reached that do not change significantly any more over the course of life.
