Can a Chipped or Fractured Porcelain Crown be Repaired?

As a busy dental office, we see some variation of this quite often:

“Doc, the porcelain on my front tooth veneer chipped. Can you fix it?”

The answer is yes, but there are some limitations. But let’s first look at a successful porcelain repair case we completed in our office.

Before and After Photos of Porcelain Bridge Repair

The photo below shows a patient of ours. He had a 7 unit dental bridge that he loved – and that had been in his mouth for over twenty years. An unfortunate slip in the bathroom led to him banging his tooth on a porcelain sink (notice the irony?) which led him to fracture off a huge chunk of the ceramic on his front tooth.

The porcelain chip was large, unsightly, and very noticeable. His greatest fear was that we would have to do a brand new bridge.

We utilized the highest rated porcelain repair kit on the market. Leveraging this product, along with our expertise, we produced a phenomenal result. It took us approximately 1 hour. And the best part is that our patient did not need a new bridge.

The Details on Repairing Porcelain

If you noticed from the beginning of this post, we said that we could repair porcelain, but there were exceptions.

Cosmetic porcelain crowns, bridges, and veneers are made in a variety of ways. But nearly every method requires the porcelain to go to extremely high temperatures – like over 1,000 degrees Fahrenheit! So to add porcelain to a crown in a predictable manner, you would need to put the crown into the firing oven. But that’s not possible given that there’s a person connected to the tooth!

So, the next best thing is to bond composite material to the fractured porcelain. Composites are the white material used in fillings and bonding. The challenge is that the bond from composite to porcelain is not that strong. Nevertheless, when done correctly, we can still get a good result, as you can see below:

His bridge was cemented in placed. So we bonded composite on there. Two years later, he still looks great!

How to Get a Porcelain Chip Repaired

If you have a chipped front crown, veneer, or bridge, you might just think you can call any dentist and have it taken care of. That is not always accurate for the following reasons:

  • Repairing porcelain is not an every day procedure for most dentists. So, many dentists simply do not know how to do it.
  • A dentist has to keep in stock a very specific (and expensive) porcelain repair kit. Most dentists don’t have this in stock.
  • Some larger fractures can be impossible to repair in a manner that lasts a while. In those cases, you may need to invest in a new crown, bridge, or veneer.

If you believe this is what you need, it never hurts to call and ask the dental office if they are able to do this type of procedure.

An Hour and Half for a Crown?

We get lots of new patients of all ages in our office. Many need treatment while others do not. Some need fillings. Some need root canals. And some need crowns.

For those patients needing crowns, we often describe the process, which includes the fact that we sometimes schedule for an hour and a half.

“An hour and a half??

That is the response we sometimes get. Some cannot understand why it would take that long. The irony of this situation is that we are often replacing a poorly done crown that had been done in less than an hour.

A 90 Minute Crown

Let’s look at before and after photos showing a crown that took 90 minutes:

The above photo shows a crown that took 90 minutes. She had two very large fillings in her upper right central incisor that were consistently breaking every 6 months.

Why did it take 90 minutes? Here are some reasons:

  • We had to prepare the tooth very conservatively (which means we went slowly) to prevent her from needing a root canal.
  • We had to create space under the gums for the crown to go. Notice how you can’t detect where the crown meets the tooth!
  • We had to get an ideal shade match.This takes time and expertise! Notice how the shade matches the other teeth perfectly.
  • We had to make a good looking temporary crown.

Needless to say, our patient was very happy with the results. Time well spent!

45 Minute Crowns

We thought we would include photos of crowns that were not visually pleasing.

Ugly dental crowns that took only 45 minutes

We did NOT do these crowns. Both patients recalled being in the chair for less than an hour.

The crowns above are from patients who came to our office seeking treatment. They were unhappy with the appearance of their front teeth. On questioning, they both indicated that they were in the chair for less than an hour. Needless to say, when we treated them, we spent a lot of time getting things right.

Are you unhappy with your smile? Do you have a black line around your crown? Are you unhappy with the shade? We can help. Call us at (203) 799 – 2929 or visit this page to request an appointment.

Why Do I Have a Black Line Around My Crown?

Many times we see patients who ask us this very question:

Why is there a black line at the gums with my crown?

As you can see on the photo to the right, there is a dental crown on an upper front tooth. In this case, because of an unsightly black line right where the crown meets the tooth, bonding was placed over it. Unfortunately, that didn’t make things look much better.

A black line at the margin of a dental crown can develop for many different reasons. Those reasons will be discussed in detail later on in this article.

But the most important point is that an ugly black line can be fixed!

Before and After Photos Fixing a Black Line

Don’t believe that you can fix these cases? Thing again! Let’s look at some before and after photos of patients we’ve helped:

This patient of ours from West Haven lived for many years flashing this every time he smiled. He did not believe that it could be fixed. We believe we convinced him otherwise. What do you think?

Fixing it took extreme attention to detail and a new all ceramic crown. Note the shade match – it matches the adjacent teeth so well you can’t even tell it’s a crown!

Why Are There Black Lines?

You can see black lines for several different reasons. These can include:

  • Placement of a porcelain/metal crown in a way so that the underlying metal is visible. This could have been avoided with an all ceramic one.
  • Significant recession of the gum tissue following placement of the crown.
  • Significant darkening of the underlying tooth so that its shadow becomes visible under a very thin layer of porcelain.
  • Leakage and/or staining from an old filling on the tooth under the crown.
  • Caries (a.ka. decay or a cavity) that develops at the margin.

Black lines – along with brown colors – visible on these front crowns. We DID NOT do these crowns!

The above photo shows three front teeth. The black and brown originate from several factors – the use of porcelain/metal crowns, recession of the gums, and leakage/staining from old fillings. Ouch!

Black Lines Can be Fixed!

As the before and after photos show, nearly all cases of black lines can be corrected. To do so, your dentist first must understand why it occurred, and then he/she must pay extreme attention to every detail to correct it.

From a Flipper to a New Front Tooth

One of the most frustrating things for a patient (and challenging for us as dentists) is dealing with the loss of a front tooth.

In many of those cases, our patients have to wear the dreaded flipper for several months or more. No one likes a flipper – they can break easily, you can’t chew hard foods, they don’t look natural, and you can easily lose it.

Below is our patient Kim whom we helped to ditch her flipper:

Due to a fractured tooth root and an infection, she lost her left front tooth. After months with a flipper, this is what we achieved! Photos and dentistry Dr. Nicholas Calcaterra.

Our patient had to wear her flipper for several months while waiting for the infection to resolve and for the dental implant to become stable. On more than one occasion, she misplaced it, and then had to walk around without a front tooth!

A Look at Kim’s Flipper

This is Kim’s flipper. You can see it is a single tooth attached to denture acrylic. It is fragile and can break easily. She did NOT like wearing it.

Ditching the Flipper with Dental Implants

So how did we help Kim? As we mentioned before, we saved her smile with a dental implant. See these photos for a closeup:

As you can see above, we gave Kim her smile back using a dental implant. She is now able to talk, smile, and chew normally.

It took significant time and expertise to match the new crown to her existing smile. We think the results speak for themselves.

And what, you may ask, did Kim do with her flipper after she left our office with her new tooth? We don’t know… but the rumor on the street is that somehow a hammer was involved…
