I am a patient requesting comment as I am meeting with my dentist and his lab tech next week:
My front teeth (#8,9) crowns, after 3 tries by the lab, came out slightly yellower and grayer than the surrounding teeth. D2 was the requested shade, which was the best match to #10. #8 has a root canal. The stumps are different colors. Prior to the shade selection by the dentist, I did tray whitening for two weeks prior, followed by about a week of no whitening. Here is the history since then:
attempt 1: crowns come in slightly grayer than shade chip but match each other. I could barely tell difference from the adjacent teeth (#7 and 10). Dentist sent back to lab with chip to match front teeth to it.
attempt 2: crowns come back, #8 very gray, #9 seemed better. Dentist sent back to lab with instruction to match crowns to each other.
attempt 3: crowns come back, both slightly yellow - with gray underneath. I mention to dentist before they get cemented in. They get cemented in. The overall color, compared to the other teeth - I would say is slightly green. The shade of the two front teeth is slightly darker than the surrounding teeth.
The shade/color difference is not extreme, however the crowns are darker/yellower than the adjacent top teeth, as well as the bottom teeth.
A second opinion described it as about a half a shade. It is visible at distances close up, less than 2 feet. It is more noticeable in natural and incandescent light, compared to flourescent light.
Upon returning to dentist to discuss this problem, the dentist considers the shade/color not bad, and if he was to redo - he recommends replacing only the grayer of the two crowns (#8) and match it to #9. My lay opinion is to disagree; I think that making two front teeth at the same time would be easier than matching a cemented crown that has been to a lab three times already. I also see the color and shade to be off on both crowns, although #8 is somewhat worse. I think the front teeth should look at least as white, if not slightly whiter, than the surrounding teeth, not more dark/colored.
I see there are a few other posts on front teeth with emax coming out a little gray. I don't know what material was used (HT or LT); all I can say is that the teeth, on the first attempt, looked somewhat translucent, they don't anymore - it seems some sort of lighter coating was applied.
In any case, the dentist is bringing in the dental lab person to look at this at my next appointment, next week, and I would appreciate any comments.
