Mismatched crown. Can anything be done about this? (Photos)

Question

I had a crown placed on #8 following a root canal retreatment. Went to the lab for a custom shade & was initally pleased with the result when my dentist applied the crown. Now that I've seen it in natural light, I'm not sure I like it so much...my tooth appears dark at the top. I'm thinking this is my tooth showing through the crown...It looks like my original tooth so I'm disappointed that I went through all that & paid so much for essentially no improvement. Can anything be done about this?

Unfortunately you would need to have the crown remade in order to mask your underlying tooth color. Your crown is all porcelain and is not opaque enough to block the tooth shade from bleeding through. The new crown might need to be a porcelain fused to gold crown, which means  that gold covers your tooth and porcelain is then baked over the gold so that it matches your teeth. The other alternative is a more opaque porcelain type crown. Either way, your present crown is too translucent to block the shade properly.

Unfortunately, the only real option is a new crown, but the shade underneath of the remaining tooth ("stump") shade   and choice of material is most important to mask the darkness and be able to match the adjacent teeth.
