How Long Can I Expect My Dental Crown To Last?

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.

How Long Do Dental Crowns Last?

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.

Why Do Dental Crowns Need to Be Redone?

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.

Cosmetic Dentistry Combines Art and Science

Cosmetic dentistry, these days, sometimes combines science with fine art. This requires a craftsman's skill to make sure the tooth restoration is as attractive as it is durable. After all, your smile is too valuable to be spoiled by unnatural-looking dental veneers.

The goal of a cosmetic dentist should be to provide you with an attractive, natural-appearing smile. You have a wide array of choices, and a good cosmetic dentistry professional should be happy to review the possibilities with you. For example, porcelain onlays and inlays can return structural integrity to a broken tooth, while leaving it looking as good as (or possibly better than) the original.

This is especially apparent if you now have metal fillings or a gold tooth. Metal and gold, after all, are not normal components of teeth. There's a huge difference between gold or metal combination fillings and porcelain dental crowns that reflect the translucence of natural teeth. Plus, porcelain restorations are now as strong, or stronger, than your own teeth. Ask your cosmetic dentist to take before-and-after photos so you can see the difference for yourself.

Admittedly, these more natural-appearing restorations are also a little more expensive. And many dental insurance plans may not cover all of the cost for cosmetic dental work. But in terms of your appearance (and the self-confidence it boosts), there's no comparison.
