I’m hoping you can advise me. I’ve had a dental crown for several years. For some reason there’s a dark line above it now. I can’t figure out what I did and I’m a little embarrassed to show my dentist. I’m hoping to clear it up before my next appointment. Plus, it’s a front tooth, which makes it visible whenever I smile.

It’s likely you didn’t do anything and have nothing to be ashamed of. I suspect you have a porcelain-fused-to-metal crown. After a while a dark line will form at the gumline with this type of crown. I’m a little surprised your dentist used this type of crown for a front tooth. These are usually reserved for back teeth.
Unfortunately, the only way to get rid of it is to have a new crown made. If you decide to do that, I would tell your dentist that you want an all porcelain crown. Not only would this prevent the gray line you’re seeing now, but you will also find it to be much more natural looking.
