Can removing a permanently cemented crown damage the abutment or implant itself?

Question

Is there any bad consequences of removing a permanently cemented crown in dental implant? Got my dental implant crown placed 4 weeks ago. I hate the color because i see a gray shadow in tooth my dentist said he can remove it by braking it and making a new crown and no need to replaced abutment.

The least risky way to remove a permanently cemented crown would be to cut it off. Using any of the crown removal techniques that don’t involve cutting could cause damage to the abutment or even the implant itself.

Hello. When you see a gray area around your crown is because is a metal porcelain crown, for that reason if you want to take It out you have to broke the crown over implant and do another in zirconia. And try to get one doctor know how to do it.

It should not cause a problem. Remember both implant and abutment are made of titanium. If it was made with a zirconium abutment, there may be a slight concern of damaging the abutment. I think you need to ask why there is a dark shadow. It may well be, in fact, the abutment or the tissue thickness needs to be improved. It's been a while since I made metal ceramic crowns on implants, and sometimes, depending on the quality of the metal that was used, if some recession occurred, you would see a dark shadow around the neck of the gum line. Without any pictures, its hard for me to really see what's going on, but if you don't like what you see, then just be ready to do whatever is necessary, including changing out the abutment.

Most dentists try in a crown on an implant and then ask for patient approval.  Did you approve the crown?  In addition, since implants sometime need updated treatment, many dentists just use a temporary cement, since there is no risk of decay, and can easily be removed.  Are you sure your dentist use "permanent" cement?  Lastly, if it was permanently cemented, it should not be tried to use force to tap off as this could damage the bone holding the implant, or even the implant itself.  Cutting it off and making a new crown may be the only option.  But in the future ,  always ask to see and approve the life-like color and fit or the restoration

There is no negative consequence to redone a new crown in dental implant . What may happen is that the abutment may be damaged and your dentist may have to perform a new one.

Removing a crown on Implant will not damage implant or abutment if done carefully.
Your esthetic problem can be solved by making a Zirconia crown over the implant abutment. you don't have to worry at all as the old crown will be cut carefully with equipment and removed without damaging the abutment or implant.

While it is true that removing crowns is NOT risk free, it is something that every dentist does routinely.  There are many ways to removed them, but generally speaking we cut a groove on the side and top of the tooth and use an instrument to spread the size of the groove.  This breaks the seal of the cement.  However, if the cement is VERY strong (bonded), then the tooth COULD break....  so if determined as very risky of fracture, then preparing the tooth like an untouched tooth can heat up the cement and it will come off that way.  This will take MUCH longer and MANY burs (drill bits).

There should be no problem removing the crown to make it more esthetic for you. The implant itself will not be damaged. Your dentist is trying to ensure that you are satisfied with the treatment you received.
