Is a Crack in a Dental Crown an Emergency?

I have had six porcelain crowns for close to twelve years. One of them, on a front tooth, has always had a slight defect. It never really bothered me because you couldn’t really see it. If I rubbed my tongue against it, there would be a slight depression but that is all. Now, it feels like there is a crack and I can see a horizontal line. I am afraid the crown will break. Would this be considered a dental emergency?

Dear Pamela,

Porcelain crown being placed on a tooth

While I would not say that you have a dental emergency on your hands that you have to try and get in today, I would schedule an appointment with an excellent cosmetic dentist and have them look at it. Based on your description, there has been a substantial change on the structure of your tooth. It is likely to break at some point in the near future.

You have a couple of options. Your porcelain crowns are aging. Because of that more of them may start failing. You can either replace all of them at once or one at a time as they fail.

What to beware of is a dentist who says that you have to replace all of them to get them to match. A single crown can be matched to the other teeth. However, it takes a highly skilled cosmetic dentist to do it.

Whichever dentist you end up with, make certain they are willing to do a temporary try-in and allow you to approve the crown before it is permanently bonded on. They need to be willing to re-do the crown if you are not 100% satisfied with it.
