I’ve had dental crowns for a while now and have never really had problems with them. Lately there is this dark line right at my gumline. Do I have some kind of infection?
No, I suspect your crowns are what is known as porcelain-fused-to-metal crowns. Whenever crowns have a metal base there are some drawbacks. One of them is they are more opaque than all-porcelain crowns. Another disadvantage is the dark line at your gumline. Eventually all porcelain fused to metal crowns will develop that line. It is not caused by anything you have done, nor can you do anything to get rid of them short of getting new crowns.
If you decide to get new crowns, be sure you tell your dentist to give you all porcelain crowns. You may also see if he or she has CEREC crown technology. This allows you to get your crown in just one visit, which saves you the hastle of a temporary crown and an additional visit.
