Posts for tag: Crowns
All crowns are designed to restore functionality to a damaged tooth. But crowns can differ from one another in their appearance, in the material they’re made from, and how they blend with other teeth.
A crown is a metal or porcelain artifice that’s bonded permanently over a decayed or damaged tooth. Every crown process begins with preparation of the tooth so the crown will fit over it. Afterward, we make an impression of the prepared tooth digitally or with an elastic material that most often is sent to a dental laboratory to create the new crown.
It’s at this point where crown composition and design can diverge. Most of the first known crowns were made of metal (usually gold or silver), which is still a component in some crowns today. A few decades ago dental porcelain, a form of ceramic that could provide a tooth-like appearance, began to emerge as a crown material. The first types of porcelain could match a real tooth’s color or texture, but were brittle and didn’t hold up well to biting forces. Dentists developed a crown with a metal interior for strength and a fused outside layer of porcelain for appearance.
This hybrid became the crown design of choice up until the last decade. It is being overtaken, though, by all-ceramic crowns made with new forms of more durable porcelain, some strengthened with a material known as Lucite. Today, only about 40% of crowns installed annually are the metal-porcelain hybrid, while all-porcelain crowns are growing in popularity.
Of course, these newer porcelain crowns and the attention to the artistic detail they require are often more expensive than more traditional crowns. If you depend on dental insurance to help with your dental care costs, you may find your policy maximum benefit for these newer type crowns won’t cover the costs.
If you want the most affordable price and are satisfied primarily with restored function, a basic crown is still a viable choice. If, however, you would like a crown that does the most for your smile, you may want to consider one with newer, stronger porcelain and made with greater artistic detail by the dental technician. In either case, the crown you receive will restore lost function and provide some degree of improvement to the appearance of a damaged tooth.
Porcelain crowns have been used to restore problem teeth since at least the early 20th Century. Crown technology has gradually progressed from the early use of precious metals like gold or silver to more life-like porcelain crowns, often with a metal interior for added strength. Today, most crowns are all-porcelain, made with newer materials that not only look attractive but can endure under the pressures of daily chewing or biting.
While crowns are often part of restorations for missing teeth, they’re also commonly used to cap or fit over a viable tooth with structural or appearance problems. Here are 4 situations where a crown could improve a tooth’s form and function.
Traumatized teeth. A significant blow to the face or mouth could generate enough force to chip away or fracture a significant amount of structure from a tooth. If the root remains healthy and firmly attached within the jaw, however, a crown can replace the missing structure and restore the tooth’s function and appearance.
Root canal treatments. Root canal treatments remove infected or dead tissue within a tooth’s pulp chamber, its inner core, and the root canals. The procedure rescues the tooth but can in the process significantly alter the tooth’s structure and appearance. A crown not only restores the tooth but also provides added protection against further decay or tooth fracture.
Teeth with multiple fillings. We can effectively treat cavities caused by tooth decay by filling them. But with each filling we must remove more of the decayed structure and shape the cavity to accommodate the filling. After a number of times, a tooth may not have enough structure left to support another filling. If the tooth is still viable, a crown could solve this dilemma.
Abnormally developed teeth. Teeth sometimes don’t erupt in the jaw as they should and may be only partly visible. The tooth not only looks out of place but it can’t fully function like a normal tooth. Capping an abnormally developed tooth with a crown will help normalize it and allow it to blend in with surrounding teeth.

Learn about crowns and bridges from your Huntersville dentist.
A Gallup poll found that up to a third of Americans didn’t visit the dentist’s office in the course of a year. Unfortunately, the longer you avoid going to the dentist’s office, the higher the chance of dental problems that may require restorative work. If you’ve been looking for a restorative solution for your smile, crowns or bridges may be your best option. Learn more about these common dental treatments by exploring a few frequently asked questions.
What Is the Difference Between Crowns and Bridges?
A crown is a whole covering, commonly made of porcelain, metal or ceramic material, that replaces the enamel layer of the tooth. It is bonded on top of a healthy rooted tooth that needs strengthening and protection. A bridge is a device that uses two crowns to fill in a gap in the smile from a missing tooth. The crowns cover the two adjacent teeth, called abutments. The center of the bridge called a pontic, is a false tooth that is designed to fit in with the rest of your smile.
Who Is a Good Candidate for Crowns?
Since a crown is only a superficial covering, the inner parts of the tooth have to be healthy to support it. A dentist must examine the inside of the tooth using X-rays to confirm that the tooth is healthy enough for a crown. Patients who have root canal therapy are also candidates for crowns.
Who Needs Bridges?
Someone who has one or two missing teeth and wants a reasonably secure and semi-permanent solution may benefit from bridges. The bridge is needed to help make it easier to process food, maintain the structure of the jawline and give the patient a smile to be proud of. The abutment teeth have to be healthy enough to support a crown. Generally, a good candidate for a crown will likely also be a good candidate for bridgework.
How Long Will These Dental Solutions Last?
A crown or bridge can last for between five to 15 years or even longer if you take care of your teeth. But no worries, because when the time comes your dentist can redo the crown or bridge and give you another 15 or more years to enjoy your new smile.
