A tooth-colored crown may be made of both porcelain and metal or it may be made entirely of porcelain. The one appointment Cerec crown produced in our office is made out of all porcelain.
In the past, porcelain crowns were always built upon a metal core. The metal core helped to reinforce the porcelain so the crown could have enough strength to withstand the tremendous biting forces that are exerted on all your teeth. The metal core is what creates the dark blue line at the edge of many crowns. In some areas of the smile, especially the front teeth, the dark blue line is unattractive and unnatural.
Breakthroughs in adhesives combined with the development of stronger porcelain materials, allow us to make crowns entirely out of porcelain. All-porcelain crowns maintain a translucency that makes them hard to tell from natural teeth. Without metal, the problem of a dark line at the edge of the gums is eliminated. This allows us to place the edge of the crown above the gumline, and that’s healthier for your tooth and gums.
We work hard to help you get the perfect smile. If you need a crown or are interested in replacing an older crown we would be happy to discuss the method of treatment that is right for you.
