Are CEREC Crowns as Reliable as Regular Crowns?

At my last check-up, my dentist said I need three crowns. I wasn’t too surprised I needed them, but he’s pretty insistent I get CEREC crowns. My insurance doesn’t cover those and they’re more expensive. I’m not sure I want to invest in something more expensive just because it’s the newest thing unless I know it’s as reliable as the regular crowns. Do you have an opinion on this?

Dear Louis,

A CEREC Machine
When Should You Get a CEREC Crown?

A lot of whether or not a dental crown is reliable depends more on the dentist than anything else. Some dentists get better results than others. However, there are times when a CEREC crown is better than a traditional one. There are times it’s the other way around as well.

Because they’re computer milled, CEREC crowns often fit better. They do well in front and side teeth, but aren’t always strong enough for back teeth. For those, you may prefer a zirconia crown or a porcelain fused to metal crown.

Their biggest benefit is you can have your three crowns done in one visit, without a temporary crown. Other than that, everything else truly depends on the skill of your dentist.

If you decide you want a CEREC crown, your dentist can bill the insurance for the regular crown and you just pay the difference, which isn’t too substantial.

Some Considerations with CEREC Crowns

Placement is the biggest issue. If it’s going to be visible and you’ve ever wanted to whiten your teeth do the teeth whitening before you have the crown milled. If it’s a visible side tooth, that should be sufficient for an attractive looking smile.

However, if it’s a front tooth, you’ll want a traditional crown. CEREC crowns are milled out of a single block of porcelain which, though beautiful does not have all the subtleties necessary for a front tooth. You’ll want something sculpted from various blocks so that the right level of translucency comes across at the appropriate parts of the tooth. Otherwise, it can look a little flat compared to the tooth next to it. You’ll know it’s a little different without knowing why. It will still be attractive, just not as attractive as it could have been.

Again, each dentist’s skills vary in this area, so ask to see sample before and after pictures of their work.

Will CEREC Crowns Hold Up as Well as Regular Crowns If I Grind?

My dentist just got a CEREC machine and wants me to get one for my new cavity. I’m a little concerned it won’t hold up as well as regular crowns. I tend to grind my teeth at night. Is he wanting me to get these just to try out his machine or are they legitimately strong? I don’t want to waste money.

Dear Greg,

Gilbert CEREC Crown

Both CEREC crowns and traditional crowns are equally strong. The biggest difference is one is milled by computer and can be completed during your appointment instead of having to be sent out to a lab to be completed. This eliminates the need for a second appointment or a temporary crown.

However, if you are a teeth grinder that needs to be addressed right away. Your crowns, whether traditional or CEREC, will not hold up to the stress the grinding places on them. Truthfully, neither will your natural teeth. It’s likely the reason you’ve had to have so many dental crowns to begin with.

Not only does teeth grinding wear down your enamel which leaves your teeth vulnerable to both decay and cracking, it also will cause jaw pain, headaches, and eventually TMJ. That can become serious.

I’m very surprised your dentist hasn’t recommended a night guard to protect your teeth. As soon as your crown is completed, you need to be fit for a custom nightguard. You won’t be able to stop grinding your teeth, especially if you do it mostly in your sleep. However, the nightguard protects them from the stress of the grinding.

After that, a well made dental crown can last upwards of 15 years.

Sensitive composite filling

I had some composite fillings placed on my teeth. I’m not having pain or sensitivity. But, one of the fillings feels a little uncomfortable when it is pressed. My dentist has already replaced it once. ¬†Does he need to do it again?

Sylvia,

Though I couldn’t be certain without seeing your tooth myself, I really don’t think you have anything you worry about. It is not uncommon for there to be some sensitivity to your white fillings for several days.

Didn’t remove braces

When I was a teenager I had braces. My parents died and I was put in the foster system. One thing led to another, and I ran away. Because I was on my own, I never had braces removed. I’m really embarrassed about that. I’m in a job where I can afford some dental care. Is there anything I can do about it now?

Kevin, Austin, TX

Kevin,

The only thing you can at this point is to have the braces removed. After that procedure is completed, you can see what kind of damage was done to your teeth. it is possible you may need to get either porcelain crowns or maybe even porcelain veneers.

Crown keeps falling off

I had an all porcelain crown placed about five years ago. Since then it has fallen out at least three times, that I can recall. My dentist has always re-cemented them for free. However, this last time, I didn’t realize it had fallen out while I was eating. I bit down again and shattered most of it.¬† Because he has to make a new crown now, he wants to charge me an additional $1400.00. Is it common for crowns to fall out this much? I wondered if it was because I got a CEREC porcelain crown.

Susan- Lehi, Utah

Susan,

No, it is not normal for CEREC crowns to fall out. In fact, if they’re done correctly, they will never fall out. You said your dentist keeps cementing the crown. If he did an all porcelain CEREC crown, then he should have bonded the crown instead of cemented it. Maybe that is what you meant and you didn’t know there was a difference.

One of the things that holds crowns is the parallelism of the way the tooth is prepared. The more parallel the tooth is prepared, the stronger the retention. However, it doesn’t take much retention in their design if they are bonded in properly.

My suspicion is your dentist doesn’t have sufficient training in the bonding procedure and that is why your crown keeps falling out.

My crowns are ugly

Quite awhile ago, like 20 years or so, I had porcelain-fused-to-metal crowns placed on my front teeth. I hate the dark line that is evident when I smile. Do you know if anything can be done to improve their appearance or change this? I have a big smile and it really bothers me. Would Lumineers work? Any advice would be greatly appreciated.

– Carolyn in California

Carolyn,

It is possible to get that beautiful smile you are hoping for without the dark lines. For an expert cosmetic dentist, the treatment is relatively simple. A general dentist does not have the artistic ability required to make this transformation beautiful. An experienced cosmetic dentist can place crowns made of all porcelain. There is no metal in them, so they will look just like your natural teeth.

I hope this information was helpful.
