People often assume that once they have a crown placed on a tooth, it will last the rest of their lives. Although dental crowns may last for a very long time, it is not correct to say that they will last forever.
This is one of the most difficult questions asked of a dentist because, in essence, no one can be sure. However, there are a few resources available that can give us an idea of how long your dental crowns may last.
One resource is insurance companies. Even though the dental insurance company should not dictate the type of treatment that should be done, they give some insight into the matter. Insurance companies will pay for a new crown on the same tooth after five years. So, in essence, they believe that dental crowns will last at least five years. Another resource available is the dental literature. The dental research has some extreme variability in this area. It provides information that ranges from a 20% failure rate in 3 years all the way to a 3% failure rate in 23 years. So, which is correct? The answer actually has to be looked at on a case-by-case basis. To do this, we need to look at why dental crowns have to be replaced.
There are many reasons why dental crowns need to be redone. Fracture is one example. The fracture incidence of dental crowns can be related to either the type of restoration (gold, metal ceramic, all-ceramic) or where the tooth restoration is placed in the mouth (anterior vs. posterior). Another risk factor is if a person has a grinding habit at night. A crown will have a higher risk of fracture in a mouth that applies more forces to the teeth by grinding than in one that does not have any incidence of grinding.
Decay can be another reason why dental crowns need to be replaced. Just because a tooth receives a crown does not mean it is less prone to decay. In fact, because it has more areas that may trap plaque, it needs to be cleaned as well, if not more meticulously, during home care.
Esthetics can be another reason why dental crowns are replaced. Esthetics is one of the main reasons people choose to have a new crown made in the anterior part of the mouth. This occurs because as we get older, our teeth will change color and progressively get darker while the tooth with the crown will stay the same color as the day it was placed. A discrepancy between the color of the teeth will become more evident over time. In addition to color, esthetic changes in the position of the gum tissue over time can also affect the look of the crown.
Which one of these areas may be a factor in a patient's mouth is uncertain. An idea can be obtained by evaluating the reason a crown was needed in the first place (such as a fractured tooth, decay, etc.). In conclusion, it is unclear how long dental crowns will last. Their life span may be anywhere from a few years all the way to 20 years and beyond. A lot of it will depend on the need for the crown in the first place and how well the mouth is taken care of after the crown is placed.

With recent advances in cosmetic dental technology, what was once considered impossible can now be performed routinely. We now have the means and the know-how to treat such conditions as discolored, crooked, and missing teeth - often in one or two visits to a cosmetic dentist, and often without discomfort.
Porcelain veneers have now become a standard part of cosmetic dentistry. These veneers are thin shells of porcelain bonded to the front teeth. Using porcelain veneers, we can change the shape, color and length of your teeth in only two visits - instant orthodontics!
Dental bonding is a widely used phrase that describes how tooth-colored fillings are placed. Using dental bonding, we can eliminate discolored areas, fill in gaps, and also build back areas of gum recession.
Composite fillings (tooth-colored fillings) can now be placed in the back molar areas when tooth decay is detected. These fillings can be used instead of amalgam (silver) fillings and are virtually invisible. Dentists have fun placing composite fillings and patients like them, too.
Teeth whitening is a great treatment for generalized yellow or stained teeth. With custom-fabricated tooth bleaching trays, the bleaching procedure can be done at home at your own convenience. The process generally takes about four to six weeks and the results are very impressive.
With the treatment options available today, it's possible to have the smile you've always wanted. Let your dentist know if you're interested in learning more about these advances in cosmetic dentistry.
