Does replacing a veneer mean grinding the tooth again?
The aim is to remove old ceramic and cement while staying inside the original preparation.
Replacing a veneer means removing the old ceramic and the cement beneath it, then taking a new impression. Done carefully, most of the work stays within the preparation that was cut the first time.
How much extra tooth is lost
Under magnification, and in some clinics with laser-assisted debonding, the ceramic can be lifted while sparing the enamel underneath. Some cement cleanup at the surface is unavoidable, and if decay is found once the veneer is off, that tooth structure has to be treated as well.
How much new reduction is needed differs case by case, depending on the original prep depth and the state of the tooth. Before agreeing to replacement, ask the dentist how much enamel remains and how it will be preserved.
