New Advancements in Cosmetic Dentistry Techniques

You'd be amazed (and probably delighted) by the options modern dentistry makes available for strong, natural-looking tooth restoration. Read on for more information about the exciting new cosmetic dental materials we have available now.

Traditionally, gold has been the "gold standard" of materials, and for good reason. Gold is highly biocompatible and is very long-wearing. A gold tooth, however, is not natural looking.

Today's a porcelain crowns or veneers don't mean choosing between strength and a lifelike appearance. You can opt for both. New all-porcelain crowns and veneers are available that look like natural teeth. They're durable enough to be used even for molars. This super-strong new generation porcelain is so resilient and tough it's being used in the manufacture of some tennis rackets!

Silver fillings (the kind that turn black) are a thing of the past. Instead, a composite resin filling can be used. And it's just as strong and durable as silver, and more closely reflects the color of the original tooth surface.

If you've had some cosmetic dentistry work done in the past, you'll be happy to know you're no longer locked into the choices of even five years ago. Modern dentistry is evolving rapidly, and fresher, more natural smiles, are the result.

Make sure your cosmetic dentist's office is interested in what's new for their patients. Ask them about other exciting new options (dental implants, teeth bleaching, onlays, inlays, etc.) they can offer you for your smile.

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.
