Just had a whole set of temporary teeth done before going to Florida. They are OM1 very white! Is there a glaze ?

Your skin tone should be taken into account when selecting your tooth shade.  A shade may look great on someone you know, but may look lighter or darker on you, depending on your skin tone. I always recommend okaying your restorations before having them permanently bonded. That way, they can easily be sent back to lab lab if changes to to shade, shape and/or fit are necessary. Click "save" under my name, if you'd like to ask me more questions in the future.

Depending on a person’s complexion, a shade that is too white can make
the teeth look false. Having said that,
people have different preferences and notions about beauty, and the patient’s
desires have to be taken into consideration.
It is possible to alter the color after the porcelain has been applied,
but that applies going from lighter to darker. You can darken crowns that are too light. If the porcelain is too dark, it has to be removed and replaced. A good lab or dentist who alters the shade
should not make the teeth gray.
