CEREC vs. Traditional Crowns

I’m considering getting a CEREC crown. Are they as good as their traditional counterparts?

Matt.

Dear Matt,

A tooth receiving a CEREC crown
Which is better a CEREC or Traditional Crown?

In one corner we have traditional porcelain crowns. Tried. True. Proven. Strong. Beautiful (with the right dentist). Though, they do take a couple of appointments. They’re milled from more than one block of porcelain.

In the other corner are the CEREC crowns. Tried. True. Proven. Strong. Beautiful (with the right dentist). Made in one appointment. Though, they’re milled from one solid block of porcelain.

Each time I type “Though”, I’m showing the downside of that particular type of crown. While two appointments aren’t horrible, it is definitely more convenient to have it done in one. You miss less work. You use less time. You have your permanent crown from the beginning. So, it would seem that the CEREC crown would be the better bargain. After all, the other features seem to be the same.

So, what’s the big deal about the “Though” for CEREC crowns? Why does it matter if you mill a crown from one block of porcelain or more than one block?

The difference comes from a cosmetic standpoint. Your teeth aren’t of identical translucency from top to bottom. The edges, especially at the bottom, are less opaque than the rest of the tooth. It seems to “thin out” a bit as you move down. There’s also a whiter color in the center than you’d find as you move down.

When you mill from a single block of porcelain, the crown will seem the same from top to bottom. They can look a little flatter because there aren’t those subtle varieties.

When a dentist can draw from more than one block and craft them together, you get the subtleties that reflect light a smidge better in natural teeth.

When to NOT Get CEREC Crowns

In most cases, CEREC crowns are fantastic. They’ll still look beautiful. They’ll still match your teeth. They’ll still hold up to the stresses of daily use. The one exception is on a very front tooth. If you’re getting a crown on one of your very visible front teeth, that’s when I would opt for a traditional crown. This will allow the dentist to use his artistry and make sure every subtle variety of light and color comes through.

Other than in that case, you will get a gorgeous crown with CEREC AND save yourself an additional appointment.

One word of caution. No matter which you decide on, once the crown is completed and bonded on, the color cannot be changed. If you’re going to get your teeth whitened, do it before getting your crown designed.

Can’t Get CEREC Crowns from My Dentist

I’m so sick of temporary crowns that fall off all the time. Every time I’ve gotten a crown it’s been a disaster from the get-go. I get a temporary and it falls off at every meal. It’s impossible to deal with. Now I find out I need another crown. I told my dentist I want a CEREC crown so I don’t have to deal with a temporary. He insists they’re not as good. I’m seriously considering switching dentists over this. What do you think?

Fanny,

Dear Fanny,
A tooth receiving a CEREC crown

I can understand your frustration. While temporary crowns do occasionally fall out (after all, they’re meant to be temporary) what you’ve experienced is way beyond normal. It says a bit about the skill of your dentist. I wouldn’t normally suggest switching dentists simply because you want a one-day crown, but it seems like your dentist lacks skill.

I’m not sure why he means they’re not as good. They’re just as strong as their traditional counterparts. The biggest difference and the only weakness I can see in comparison is CEREC crowns are milled out of a single block of porcelain. Some dentists feel that for your very front teeth it would look better for you to have a traditionally made crown so the dentist can craft it from several blocks of porcelain giving it more natural variety.

Cerec Crowns and Teeth Whitening

One other thing to consider. Hopefully, your dentist told you that once crowns are milled, their color is permanent. If you want your teeth whitened, you should do it before getting this latest crown if it is in a visible part of your smile.

That way your dentist will match your crown to the new color. Of course, if any of your old crowns are visible, those will need to be re-done to match. If they’re on back teeth which don’t show while you smile, I wouldn’t bother changing them though.

Picking a New Dentist

If you do decide to switch dentists over this issue. May I suggest you consider every type of procedure you may want, even future. If it’s just a good general dentist you want, who keeps up with the latest technology, that won’t be too hard to find.

If, however, you have more cosmetic interests in your future you’ll want to find a highly skilled cosmetic dentist. If they keep up with the advances in cosmetic work, you can be almost positive they keep up with the general side as well. So, how do you find an expert cosmetic dentist in your area? I’d check the American Academy of Cosmetic Dentistry’s website. You’ll want to be certain to get a dentist who’s reached accreditation level.

Do CEREC Crowns Last Longer than Regular Crowns?

My dentist told me I need three crowns. I was shocked because my last checkup didn’t show any decay. He wants me to get CEREC crowns. I like the fact that they can be done in one appointment. But, my insurance only covers the older crowns. Is it worth the extra cost? Do they last longer than the regular crowns?

CEREC Crowns are Milled by Computer

When you’re talking about the longevity of crowns, it’s not as much whether you use CEREC or traditional. The length of time any crown lasts, regardless of the kind, depends on two factors—the skill of the dentist and the habits of the patient.

On the patient end, it’s important you keep up with your home care. Regular brushing and flossing are a must. The dentist has several responsibilities. They have to choose the right materials. They have to know the proper techniques for attaching the crown. Traditional crowns are cemented. CEREC crowns are bonded, which is a completely different (and more involved) technique.

Two dentists can make the same crown. One will last five years; the other will last ten. It wasn’t a difference between the type of crown as much as the skill of the dentist. Don’t hesitate to ask your dentist how long his crowns typically last.

The Differences Between CEREC and Traditional Crowns

There are two advantages to CEREC crowns. The most obvious one is you can have all three of your crowns completed in one visit. Second, they’re milled by a computer which generally helps with their fit. They’re actually great for side teeth. Some cosmetic dentists don’t like placing them on front teeth because they’re milled from a single block of porcelain. In that case, they feel they can craft them better traditionally.

Another weakness for CEREC crowns AND traditional all-porcelain crowns are on back teeth. They can’t always hold up to the pressure of the biting forces your molars have to take. In that case, you’d want either a metal-based crown or a zirconia crown if you have any metal sensitivities.

No matter what crown you choose. Once the crown is made, the color is permanent, so if you’ve been considering teeth whitening be sure to do it before you get your crowns if they’re in a visible place. If they’re all back teeth, that won’t matter. You can get your crowns and then whiten later.

Consider a Second Opinion

One thing you said bothered me. You mentioned your last checkup showed no signs of decay and suddenly you need three crowns. That sounds just a bit hinky to me. While it’s possible that you could have decay that spread quickly, if you get regular cleanings there should have been some sign of decay.

Dentist Won’t Let Me Get a CEREC Crown on Front Tooth

One of my front teeth needed a dental crown. I am tired of going to the dentist’s office and told him I’d prefer the one visit crown. But, he told me he never does those on front teeth. Shouldn’t that be my choice?

Mel

Dear Mel,

Machine for CEREC Crowns

I realize you said you’re tired of going to the dentist. But, let me ask you if going one more time meant the difference between a beautiful, natural-looking smile or something that looked good but just a bit off, would you be willing to make the extra trip?

CEREC crowns are wonderful. They’re attractive, they’re strong. But, they’re milled from a single block of porcelain. Your front teeth are so visible and receive much more light than the rest of your teeth that they need all the natural subtleties that you can only get by using different porcelains. Traditional all-porcelain crowns don’t have that problem because your dentist can craft them using more time.

How to Find a Dentist Who Can Give You a Gorgeous CEREC Crown

Very few dentists can give you a stunning CEREC crown on a front tooth. But, if you absolutely cannot handle the idea of two appointments, you’ll need to go to the right dentist. Ideally, you’ll want a dentist who is accredited by the American Academy of Cosmetic Dentistry (AACD). These dentists have past stringent exams and demonstrated their artistry in creating beautiful smiles.

Something you should also be aware of is any type of dental work, such as dental crowns, white fillings, or porcelain veneers will not whiten like your natural teeth. The color your dentist makes them is permanent. If you’re considering whitening your teeth, you’ll want to do so before you get your crown so it can be made to match your new whiter teeth.

Can CEREC Crowns Handle Night Grinding?

My dentist recently purchased a CEREC machine he’s very excited about. I have a cavity that he feels is too large for a filling. He wants to me have a crown done using the machine. I just wanted to get a second opinion as to how they hold up as well as normal crowns. My dentist said I grind my teeth at night. I’m assuming he would only give me a crown that would hold up against that, but just wanted to double check.

Lizza

Dear Lizza,

Machine for CEREC Crowns

This is one of those yes and no answers. CEREC crowns are every bit as strong as traditional crowns. The biggest difference is they’re able to milled at the time of your appointment, eliminating the need for either a temporary crown or a second appointment.

However, I’m truly concerned about your grinding. When your dentist mentioned to you your teeth showed evidence of nighttime grinding, did he suggest anything to you, such as a nightguard? Your teeth need protecting. The stress of grinding will not only wear down the enamel of your teeth down, but can also lead to your teeth cracking and breaking.

When your enamel wears down it leaves you vulnerable to decay. With decay, you’ll be looking at a mouth full of fillings. Even worse, would be the possibility of losing a tooth. Then you’re looking at getting a tooth replacement, such as dental implants or a dental bridge.

While your choice of crown is fine, just like your natural teeth, it won’t stand up under grinding without you having some type of nightguard to protect both your natural teeth and your crowns.

Can CEREC Crowns Give Me Vampire Teeth?

I just found out I need a crown on my cuspid. I’m kind of excited about it. I’m a huge Goth fan and have always wanted vampire teeth, so I’m thinking about getting both cuspids crowned. My dentist uses a CEREC machine. Will that be able to give me vampire teeth?

Abby S. – Branson, MO

Abby,

There’s another Abby who’s a Goth fan, but she’s a fictional character on NCIS. If you haven’t seen that particular program, I bet you’d enjoy that character. In regards to your request, there are a few things to consider here. First, just in answering your question, yes, CEREC crowns could shape you pointy cuspids. However, that doesn’t mean your dentist will be willing to do it.

Every year, generally around Halloween, dentists get requests for vampire teeth. Most patients are satisfied with some temporary teeth. Every once in a while we get someone who wants them permanent. Dentists are hesitant to do that because they don’t want to be responsible for damage done to another person as a result of their cosmetic work.

Discuss it with your dentist. He or she may be willing or they may only be willing to give you temporary vampire teeth that are easily removable. This way you can use them in appropriate situations like a party or CON, but it won’t interfere with your everyday life. In fact, you might find it difficult to obtain employment with vampire teeth, which is something to consider.

Finally, I’d like you to think about the drawback of putting a crown put on a healthy tooth. Dental crowns, whether they’re CEREC or otherwise, require a large amount of tooth structure to be ground down. Your tooth essentially is reduced to a nub. I wouldn’t recommend doing this to a healthy tooth. If your dentist agrees to permanent vampire teeth, then I’d suggest getting the healthy tooth reshaped using porcelain veneers instead of crowns. You can get the appearance you want with minimal disruption to healthy tooth structure.

Are CEREC Crowns Worth Switching Dentists?

I need to get a dental crown. My sister told me to make sure and get a CEREC crown, but my dentist said he doesn’t do those. My sister seemed to think it was really important. Is it worth switching dentists to get one?

Amelia L. – Ft. Worth, TX

Amelia,

The only real benefit to CEREC crowns is they can be done in one appointment.  While it is convenient, I wouldn’t necessarily think it’s worth switching dentists.

The reason it can be done in one appointment is that it is milled on site from a single block of porcelain.

The bigger issue would be where the crown is being placed. If it is a front tooth, you’ll want to be certain your dentist is experienced and artistic with cosmetic issues. You want to make sure that he can make the crown look both beautiful and natural.

Can I Get A CEREC Crown If I Grind My Teeth?

I’m scheduled to get my first crown in a week.  I’m nervous about it. One of the things I’m worried about is my teeth grinding habit. Will it hold up as well as my teeth? I don’t know how to stop the grinding. I only know I do it because my husband mentioned I do it in my sleep.

Amanda K. – Montana

Amanda,

I’m bothered by some things you’ve mentioned. You asked if the CEREC crown will hold up as well as your teeth. The answer to that is yes.

However, your teeth won’t hold up to the grinding habit, so neither of them will. Eventually, you will grind your teeth down to nubs. It can even cause you to crack your teeth.

What you need to do is get a mouthguard for while you’re sleeping. It will protect both your natural teeth and the CEREC crown.

I’m surprised your dentist didn’t mention this to you. It’s something you really need to discuss with your dentist. The mouthguard can be custom made to fit your exact smile.

My Dentist Refuses to Give Me CEREC Crowns Even Though He Does Them

I need a crown on my front tooth. My dentist CEREC crowns, but absolutely refuses to do it on my front teeth. I really like the convenience of one appointment crowns. Can you think of a reason he won’t give it to me?

Marcella M. – Idaho

Marcella,

I suspect it is an aesthetics issue. You see, CEREC crowns are milled out of  a single block of porcelain. That means they don’t have th subtleties that you find in your natural teeth. That is fine for most of your teeth, but your front teeth are quite visible. Your dentist will want to make sure they get all the variation to make them look natural.

If he does a traditional crown, it will take a little longer, but he can do it beautifully. Of course, it is up to you. If you want a CEREC crown that badly, you can likely have one–from another dentist who doesn’t care as much about the aesthetics. Just know they’ll be a litle flat looking.

Why Is My CEREC Crown Getting Stained?

I’m having a problem with my CEREC crown. I’ve only had it about a year and now it’s picking up stains. I don’t know what happened. I just got my teeth cleaned. My teeth, including my crown, looked great when I left. A few weeks later and it started getting dingy.

Corinne – New Mexico

Corinne,

I can’t be certain without examining your crowns, but it sounds like your crown has lost its glazing. I suspect, because it happened just after your check up and cleaning, you likely had an inexperienced hygienist. He or she either didn’t realize you had a CEREC crown or didn’t know how to care for them.

If the hygienist used something like a prophy jet during your  cleaning, it would damage the glazing.

I’d talk to your dentist about it. If he or she doesn’t know how to fix it, they might be willing to replace it.  Other than that you’re stuck either living with it or replacing it yourself.
