Medical Forum / General / Dentistry / December 2005Porcelain crown removal
Hi, I just had a new porcelain crown installed (tooth #10) After it's permenantly cemented I noticed that the tooth is significantly shorter than its symmetrical counterpart, creating a visible gap between the upper and lower teeth, so of course I want it redone. Is there a risk-free way of removing a permenantly cemented crown? My dentist says that since the tooth inside is weak (has a root canal) there is a big risk of breaking it while trying to cut the crown. How good is the Richwil crown removal stuff? Any opinion from you pros out there is appreciated. Thanks, -Onur > Hi, > [quoted text clipped - 11 lines] > Thanks, > -Onur Richwill is probably less risky than most other commonly used methods. But in my experience it mostly doesn't work, esp. with anterior crowns. There is no risk-free method, either for the crown or the tooth. But any method that tries to take the crown off in the long axis of the tooth will be less likely to fracture the tooth.

You go down to the dentin, insert an elevator and try to crack it off. If it doesn't break, I'd make a horizontal score (mesio distal and then try opening from the axial score again. If this crown has a zircon reinforcement in it, I guess this wouldn't work.

You're saying, cutting the crown off is the riskiest? -Onur No. Cutting off the crown carries the smallest risk. Dartos > Just wanted to make sure I understand your reply.

If it's that risky, I would have to live with it then. It doesn't look horrible as is, it just bothers me that I'm going to pay a thousand dollars for something that I will hate every time I look in the mirror. My dentist has been advicing not to try to remove it because of the risk of damaging the tooth, but I was thinking he's exaggerating because he's going to have to pay for the new tooth. After all, it's not my fault that the tooth is short. -Onur I don't think you have interpreted some of our post as they were meant. W_B said cutting off the crown was the least risky. I stated that I have never had a tooth fracture cutting off a crown in the last 26 years (I would guess that I have done a couple of hundred over that time span). If it is bonded porcelain, it will take more time, but it still shouldn't be a very big risk (not the same as 'risk free', but it wouldn't stop me if I was unhappy with the esthetics). Only if the post/build up were a 'Hail Mary' attempt to retain the tooth for a few more years would I be concerned. If this were the case, you should have been made aware from the beginning that the treatment was risky in and of itself and may be compromised esthetically to reduce stress on a tooth that is likely to fail. For a dentist who placed a crown stating that it is risky to cut it off and redo, sounds like he just doesn't want to redo it (IMO). That said, I'm sure that you are looking at the crown with a much more critical eye than anyone else. Esthetics is not all science. A picture would sure give us an idea if things were way off.

I'm a graphic designer and so you're right, I probably have a more critical eye.

I doubt that most people would notice, but I can see why you would like it to be better. If I had done the work, I would agree to fix it (of course, I try not to cement something that is not acceptable in the first place). Some dentists differ.

I have had a couple fracture using a traditional crown puller. An anterior crown should not be permanently cemented until the esthetics are checked by both the patient and the dentist.
