What should I do if my CEREC crown broke?

Two weeks ago, I had a CEREC crown done. I was recently eating, when I felt something come loose in my mouth. I came to find out this crown had broken in half. The dentist offered to fix the crown free of charge. While I was thankful for this, I wanted to know why this happened. I want to be sure this was just a fluke circumstance and not an error made by the dentist.

Dear Randi,

While this is quite rare, there are some things that may have hinted that something was “off”, like tooth pain, jaw pain, or if the tooth was connecting first when you bit down.

Another possibility is the way the material handled stress, though it is unlikely that this is the case. However, if this were the case, it is possible there was some sort of defect in the material before use, though this, too, is unlikely.

Another thought is if you grind or clench your teeth, this may be the cause. Each tooth has a different threshold in terms of the amount of force it can withstand. This is why some restorations my break, while others do not. If this occurs during the day, practicing relaxation exercises can help. If it’s taking place at night, a night guard will prevent the grinding.

The majority of crowns can handle this to an extent, so you can’t rule out the material used or a mistake made by the dentist. It’s worth having him redo the procedure. It would be good to see what he thinks is the cause. Dentists have restorations fail from time to time. So long as this is not the norm, and he wants to fix the issue, it sounds like you’re in good hands.

CEREC Crown Disaster

Everything I’ve read about CEREC crowns and their procedure leads me to think my dentist was way off on how she handled my particular case. What’s done is done, but I just need to make sure the sensitivity I’m feeling is normal and will go away after some healing or if I have a problem. When the dentist did my crown, she said my tooth was in too bad a shape to get a good image so she was just going to pull one from a CEREC database. I wasn’t too worried because the advertisements all talk about how perfectly these crowns fit. Well, it didn’t. It was too big all around. She spent well over an hour grinding down all the sides of it. Not only was that remarkably uncomfortable, but it doesn’t even look like a real tooth anymore. It looks more like a box. Plus, every time I eat or drink something cold it zings me. Will that end after a period of time or do I have a problem on my hands?

Dear Dirk,

Gilbert CEREC Crowns
A CEREC Machine

You have a problem. You’re also right that this seems to be a disaster. CEREC crowns should be able to be placed in minutes. I have no idea what your dentist meant by your tooth was in too bad a shape to get a good image. It’s only teeth which are in bad shape that need a dental crown to begin with. I have no idea why she couldn’t get a clear image.

The only thing I can think of with an image database is when she input into the CEREC machine which tooth she was going to crown. It will give her a basic image to work from, then she’ll put images of the surrounding and opposing teeth so the computer can design a crown with a perfect fit. It sounds like your dentist had absolutely no idea what she was doing.

Get a New CEREC Crown

The sensitivity to cold concerns me. It sounds like your dentist left an open margin. That not only causes some pain when you drink something cold, but it also allows food and drinks to get trapped in there. You don’t want to leave any opening for decay. A mistake like this can cost you your tooth. Then, you won’t be trying to get a crown, but a complete tooth replacement.

You need to get a new CEREC crown made. But, you’ll want to go about this in a way that won’t cost you any more money. You’ll first need to get a second opinion from a dentist verifying everything I’ve said so you have ammunition. Do NOT tell the second opinion dentist the story you told me. Just tell them you want them to look at your crown. Also, do NOT tell them who your dentist is. You don’t want any friendship or misplaced sense of loyalty to cause them to waver in their true opinion. If they pressure you to know, tell them you’ll let them know AFTER they give their opinion. Tell them you just want their pure, untainted thoughts.

Once what I suspect is confirmed, don’t just ask for a refund. Your dentist should also pay for any expenses you incur to fix her botched job.

I hope this helps.
