Best crown for a RCT front tooth?

Hi:Your dentist is correct in being concern about the darkening color of the tooth showing through.  You can get layered zirconium crown which are more aesthetic.  Also emax done properly with the opaque cement should work.Best,Dr. Maddahi

You have a great question. All-Porcelain crowns in my opinion are the best esthetic choice for front teeth. I particularly like the Emax crowns as they are very lifelike. However, if your tooth darkens over the years from the root canal it can alter the shade and make it darker. Another choice is a zirconia crown with porcelain layered over it. This would virtually eliminate the risk of darkening if your underlying tooth darkens over time. I would also suggest a custom shade by your dentist's lab technician as this will give you the best chance of totally matching the shade of your other teeth. You are correct that full zirconia crowns are more opaque than other all porcelain crowns. However, if you do Lava crown which is the zirconia core to porcelain crown it should meet your goals. Hope this helps.
