Can porcelains crowns be lightened in color by lab?

Question

Lab tech told me at color match that once he makes the crowns and they are done, he can make darker but not lighten. Well I got the crowns and they are too dark. Dentist said he spoke to lab tech and he can lighten them. I'm confused why he told me he could not when I first met him. Should I trust?

Hello there,It sounds like you're unhappy with the shade of your new crowns.  Generally, the lab will remake a crown if the shape and/or shade is off.  Be sure that you're happy with the way your crowns look before having them permanently cemented.  It's always important look at before and after photos when selecting a dentist.  This will give you a pretty good indication of what you can expect. Good luck and I hope this helps.

If the shade is only slightly off, highlights can be added.If the shade is WAY off, it is very difficult to lighten and a new crown is typically made.Sincerely, Dr. Reiser

While in SOME cases extrinsic stains can be polished off and give dental crowns and veneers a lighter color, the rule of thumb is to go from light to dark.  This is usually accomplished by a process of staining.
