Is my veneer bonded correctly to my tooth? (photo)

I agree with the other dentists on your question - it is very possible there is a problem with the bonding.
There is a possibility however that your tooth is 'blushing'. This is where the preparation of the tooth went very close to the pulp and there is shine through of the pulp. The position of the pulp varies greatly and in some areas it can be a lot bigger (and so closer to the surface of the tooth). Sometimes this is linked to sensitivity immediately, at other times a while later.
I hope that your problem is due to an adhesive / bonding issue because a blushing pulp often ends in a root canal treatment. Try taking anti-inflammatory medications in the first instance to help and good luck.

Hi:
There seems to be an issue in the bonding process or not enough tooth structure was removed at the time of the preparation.  Most likely the veneer has to be replaced.
Best,

There's some sort of imperfection going on with that front tooth. If this was not visible at the veneer try-in then is an issue with the bond. Very easy to replace and you would have a temporary in the interim. Good luck!

That veneer need to be changed.  It  looks like the bonding material has failed, or maybe the bonding material was not  placed evenly to the veneer before placement.  your doctor should replace that at no charge.  

Sorry to be the bearer of bad news but that has to be redone. Either there was a bonding failure, failure in the veneer or moisture when placed but it must be redone.  Your dentist should replace at no charge

Nice photos!There is some imperfection in the finished and seated veneer.Assuming it is not a surface stain that can be polished off, it likely will need to be replaced. Perhaps there was an imperfectionin the porcelain, or some contamination during bonding.Your dentist doesn't like the situation anymore than you do, and should work with you to correct it.If the dental office could see you sooner, that should relieve some of your anxiety. Give them a call!

Veneers are cosmetic treatments for teeth, they should look beautiful.  If the looks are not good, then it is not serving it's purpose.  I would warranty this if it were my dental work and replace, could be a dark spot on the natural tooth or too translucent cement used or a thin spot on the veneer.  If you do not like it, insist to have it replaced since it is new, if the dentist refuses, find a CEREC dentist whom can do this for you in just one visit.

It looks as if if air, or something (saliva, blood, etc) is between the veneer and tooth causing this shadow.  It happens to the best dentists sometimes.  
You may need a new veneer.
