My Root Canal Tooth is Crowned with All Porcelain and Shows Through Dark, Dentist Suggest Porcelain Fused to White Metal?

My two front teeth have root canals and both got crowned with all porcelain at seperate times, but one crown shows through dark grey from the dark root i think, dentist suggested a new crown which is porcelain fused to white metal. Will that type of crown show through as a dark line at my gum and block out the grey colour?

You have Several Options.

With the more aesthetic qualities of other crowns these days, porcelain fused to metal is not the best choice. I would go with Lava and probably mask the dark color of the natural tooth root.

Dark root under crown showing through

I would stay away from a porcelain fused to metal crown as you may have issues with some of the metal showing at the gumline. I would look at a zirconium crown and get another opinion

What to do about Porcelain Crown on Front Tooth that had Root Canal and looks Dark

Remember, one of the most difficult tasks in cosmetic dentistry is to match a single front tooth cap to the adjacent one. That being said, there are other alternatives to porcelain fused to metal. You might be OK with a Zirconium Crown which is usually opaque enough to block out the dark underlying tooth. It can have porcelain fused to the front of it to try to match the porcelain of the adjacent tooth, but don't expect it to match perfectly under close scrutiny.

Dark tooth showing through Porcelain Crown

The other Dentists have given you solid advice. I might only add that the dark tooth can be masked and made to look very natural in the hands of a high competent Dentist / Ceramist Team if all are patient and motivated to get it right

Just my exp...I have a single front tooth crown after a root canal. I had it crowned in 1996 and then had it replaced in 2012. I never had a metal fused crown and never had a metal post, but I have had a dark gum line. Fortunately I don't show my gums when I smile much but if one looks, they can see it. I had a terrible time getting a color match. For me they used Empress vs Emax porcelain and I'd recommend asking them to bring in the lab tech for custom staining. I had to go back 8 times before they got it right and finally brought in the lab tech, however now I am still not sure I am happy as light bounces off this crown differently vs natural teeth. I'd recommend skipping your local DDS and finding a cosmetic dds for a crown. If I could do it over again I'd at least ask my local dds to bring in a consulting cosmetic dds. Just my exp. Hope it helps someone.
