I received two porcelain veneers on my front teeth a couple of years ago. I only needed one but ended up getting two. The dentist said that was necessary to make sure my two front teeth match. It worked out, they matched and looked very nice. I’m concerned because one of them has developed a dark line at the very top. Will this happen to both of them? Is there any way to fix it? It’s a little embarrassing.
Porcelain veneers shouldn’t ever develop a line at the top. There are two possible scenarios, but both mean your dentist didn’t do the job correctly. That actually wouldn’t surprise me because he told you he needed to do two veneers in order to get them to match. If he were a skilled cosmetic dentist that wouldn’t be true. He could match a single veneer to the rest of your teeth.
First, the veneers should have been made flush with your natural tooth. If your dentist didn’t do that, it would leave a ledge which can gather all kinds of food and bacteria. That would be a possible explanation of the dark line. It will also lead to decay so he should repair this free of charge.
A second possibility is the dentist didn’t bond the veneer properly. This allows things to slip in between. This would more likely make the entire veneer look darker. Unfortunately, it also will lead to decay and should be repaired free of charge.
I’d get a second opinion from an expert cosmetic dentist, just to get an objective opinion as to what is going on. Don’t be surprised if he tells you what you actually have are two porcelain-fused-to-metal crowns and not porcelain veneers. Those DO develop a dark line at the gumline as a matter of course, but generally it takes more than two years for that to pop it’s ugly head out. If this is the case it’s just another piece of evidence that your dentist isn’t qualified in cosmetics. Front teeth require all-porcelain crowns. The metal based ones are better for back teeth.
