CEREC Crowns Doesn’t Fit

I thought CEREC crowns were supposed to be more accurate because they are milled by a computer. I had a four-year-old crown break so I needed to get another one. I was in a hurry and my dentist just got the CEREC machine that is supposed to create your crown in one appointment. When I got the crown it was way too bulky. I came in again and she could see it was too big in spots. While she did grind it down in some of those spots, I am biting my tongue now every time I eat. Is this technology not what she painted it to be or is something else going on?

Dear Mark,

porcelain block for CEREC crowns

I think the problem here is more your dentist than the CEREC technology. First, she provided you with a dental crown that broke after just four years. They shouldn’t break, especially when they’re that “young”. That by itself tells me she struggles with some basic dental skills.

Now she has this great new technology. Normally, when you are preparing a crown with the CEREC machine, it is basing it off of a tooth that is already there and has been scanned into the program. Because your tooth already had a dental crown and now that was broken and gone, there wasn’t a previous tooth for her to base the crown on.

That being said, the software has the ability for the dentist to design a crown for a tooth that is no longer there. It’s fairly easy to shape the tooth using the software. The problem is she doesn’t know how to do that yet.

You have a couple of options here. The crown needs to be replaced. It also needs to fit so perfectly you don’t even know it is there. Nor, should you bite your tongue because of its fit. You can either have her provide you a traditional crown that is made in a laboratory, but again, I’m concerned that the last one only lasted four years.

Alternatively, you could just ask for a refund and go somewhere else to get your crown done. You may want to do this to make sure you get the right crown.

Must I Go to an Oral Surgeon to Get Dental Work Done?

My dentist tried to numb me for two different procedures. Neither time worked. I’ve always ended up having to go to an oral surgeon and have my work done with an I.V. that knocks me out. That makes getting any dental care quite expensive. Am I condemned to spending a fortune and still not having healthy teeth? Have you heard of someone in my situation before? Is there a different solution?

Hi Matt,

Someone asleep from dental sedation

Yes, I think I know exactly what is going on here. The great news for you is there is a solution. One thing I’ve found is that patients with dental anxiety have trouble getting numb. Sometimes it will seem like the numbing medication is working but once the work starts, they can feel pain. However, if they can be relaxed with something like nitrous oxide before the Novocain is administered, then when they are relaxed give them the numbing medicine, it works almost every time.

Some patients have such a high level of anxiety that they need a stronger level of sedation. For those patients, I recommend oral conscious sedation.

For either of these, you will not have to see an oral surgeon. Just do an internet search for a “Sedation Dentist”. They are able to help you in the office, saving you a good amount of money. You will also find that if you use oral conscious sedation, your dentist will be able to do a lot more work in each sitting. This will allow you to catch up on your work more efficiently. In fact, you’ll probably sleep through all the work.

One thing to be aware of, however, is oral conscious sedation, though administered with a simple pill, is so strong you will need someone to drive you to and from your appointment.

Once you’ve caught up with your work, if you’re looking for a quick, inexpensive way to improve the appearance of your smile quickly, I’d consider teeth whitening. That one procedure takes years off the appearance of your smile.
