Can I do an internal bleaching on a tooth that has a ceramic crown?

Question

Hello, some years back I had a trauma on my front tooth. It got darker, and I’ve made an internal bleaching at the time. Some years passed and on that tooth I put a ceramic crown. At the time looked great, but now, after 3 years I notice that my tooth is darker again. It’s noticeable a darker color inside the crown. My question is, can I do an internal bleaching again on this tooth that has a ceramic crown?

You pose an interesting question. The short answer is yes. As the other dentist suggested the access hole weakens the crown--that said, it would be a more conservative option before replacing the crown. Certainly an option to try. Good luck

The crown would have to have a hole drilled into it in order to access the chamber for internal bleaching. You risk the crown fracturing or coming off. Then the hole would be patched with filling material. That can sometimes leave an area that isn't smooth or can trap food and cause decay. You should discuss the risks/benefits with your dentist prior to making your decision.
