Whitening my front 6 Crowns, how do labs accomplish this on something that is supposed to be color stable?

Normally the lab would remove the surface layer of the porcelain and replace it with a lighter shade porcelain. This is an easy and common lab procedure.
That's a great question. The only way to whiten already made crowns is to remove porcelain from the crowns and replace it with a lighter shade of porcelain. There is no magic crown whitening formula.
