Black line with porcelain fused to metal crowns

I have porcelain fused to metal crowns on six of my top front teeth. What can be done to get rid of the the black line where the crowns meet my gums? It was not this bad when they were first placed but over the last two years it has really become noticeable. What are my options, from least expensive to most expensive?

Dear Vienne,

There really is not any inexpensive way to address this issue. The entire structure of your crowns is the problem. A dentist could try to drill away the black line and cover it over, but there is likely a serious color match issue between the roots of your natural teeth and the color of the veneers. Trying to blend those colors together in that tiny space would be incredibly difficult if not impossible, and the results would almost certainly be very unattractive.

Essentially, you have to options: live with the black line, or replace the porcelain-fused-to-metal crowns with allĀ ceramic or allĀ porcelain crowns. Be absolutely certain you chose a skilled, artistic, well-trained cosmetic dentist to do this procedure for you. I would hate to see you spend thousands of dollars to still be unhappy with the results.
