Hi, I had 8 veneers placed on my upper teeth about 12 month ago. Recently I started noticing grey lines near the gum line which made veneers look darker than they were. When I went for a second opinion to the different dentist, she said veneers were not bonded properly and moreover, the shape of them not smooth enough under the gum line which creates a "shelf" for bacteria to grow (x-ray showed no cavity under veneers though). Could this be a cause of these gray rims near the gum line?

Answer: Grey Lines post op.
Without knowing the history of your case it is hard to be 100% sure. However, I would agree that it is probably a bonding issue most of the time. Where you gums bleeding when the temporaries were take off?? How long where you wearing the temporaries?? It is possible that some blood or saliva contaminated the bonding procedure, and that the gray lines are showing that. Have any of the teeth had root canals?? Sometimes after a root canal the root can turn dark and give the tooth a gray appearance. If your veneers are over contoured at the gum line and rough, it may be possible to have the dentist recontour them, and see if that helps?? Do you smoke?? It could be possible the gray is staining of the resin cement used due to smoking. I would recommend recontouring them at the gum line first. However, be prepared if you do not get the results that you like, you may need to have them redone.

Answer: Grey line at margin of veneers
If the cause is only the "bulkiness" of the margins, resulting in bacterial build-up, then it would be worth trying to polish the margins "razor-thin", and see if that helps. If the cause is "poor bonding technique", however, then you have no choice but to remove the veneers and begin again. You really have nothing to lose (except time and a few dollars) trying to "thin - out) the margins first, unless it's obviously a poor bonding.
