How hard is it to remove 6 zirconia crowns and will it be likely a tooth would break during the process ?

Question

Recently got 6 zirconia crowns on front 6 teeth. 5 of these teeth hAve had root canals years back. The dentist commented that my teeth were very dark colored. Is this why he chose the zirconia? I was under the impression I was going to have all porcelain. It's only been a short while but I'm not happy with them. Too white and not natural looking. Would it be too traumatic to my root canal teeth or the one live tooth I have left of the 6. I've read it can take hours just to get one drilled off

Vicki Borowski, DDS · Answer

Zirconia is an all porcelain type material that is often used to block out very dark teeth. Sometimes they can become overly bright in color if too white of a shade is used. I think this is more of a laboratory technician and dentist communication issue than a materials issue. Removing zirconia crowns can be tough but there are burs that are specifically used to remove them. It shouldn't take hours, but it does need to be done very cautiously to protect the teeth underneath. I would make sure that your dentist has a plan for correcting this issue before you have the crowns removed. Also, scrutinize the crowns before they are cemented to make sure this doesn't happen again.
