“I had some crowns done a few years ago, and I was pleased with them in the beginning, but more recently I’ve noticed they have what looks like black lines around the top. Is there anything that can be done?”

Of course! This is quite a common complaint. Crowns can be made of several materials. One option, is to have metal inside and the porcelain ontop of this. Sometimes, this can become visible and hence you see a black line at the margin of the crown.

Here at Buckle & McGrath, a great deal of the time we will use crowns that do not have any metal inside, which will avoid the problem occuring at all. If, there is a need for metal, our crowns will be made in a way that conceals the metal and still avoids anything becoming noticable in the margin region.
