Cosmetic Dentistry, Restorative Dentistry, The Dental Crown And The Gold Crown

In restorative dentistry a dental crown, or caps for teeth, look and function just like natural teeth. Your cosmetic dentist may recommend a dental crown if your tooth has enough decay that it cannot hold a filling, or if your tooth is cracked or broken and in danger of cracking down into the root if left unattended. A dental crown covers your tooth completely. It fits snugly at the gum and protects what remains of the natural tooth.

Why Have A Dental Crown?

The dental crown serves two important functions. First, it restores the appearance of your teeth and your face. If your tooth is severely decayed or cracked, your cosmetic dentist will need to restore it prior to preparing a cap. Teeth also support the muscles in our faces, so anything less than a full tooth may affect the way you smile.

Second, a dental crown will be the same size and shape as the natural tooth. As a result, it will keep your jaw and bite aligned; it will also make sure that other teeth don't shift locations or take on a greater share of the work of biting and chewing.

What Is a Dental Crown Made of?

A dental crown is most often made of gold or porcelain. A dental crown also can be made of stainless steel, but those are often temporary and not designed for long-term wear.

A porcelain dental crown is usually built on a metal base, which fits snugly over the natural tooth. Your dentist will choose a porcelain that matches the color of your natural teeth. A porcelain dental crown is usually so carefully matched in color, it cannot be distinguished from your natural teeth. Many people choose porcelain dental crowns for the cosmetic appearance and the confidence it give them.

New materials are now available in cosmetic dentistry that allow your cosmetic dentist to use an "all-ceramic" dental crown in some cases. They have a beautiful life-like appearance and short-term studies support their success, with long-term trials ongoing.

A dental crown can be made of all gold. Some people prefer not to use a gold crown because it stands out from the other teeth in appearance. At the same time, if the gold crown is on a back molar, some people feel the cosmetic issue is not a big one. Your cosmetic dentist will discuss the types of materials available if a gold crown is recommended.

An Ounce of Prevention Is Still the Rule!

Once your dental crown is in place, make sure the area is brushed well and that you floss below the gum line. While the dental crown protects your remaining tooth from further decay, you must protect the base of the dental crown from bacterial growth and gum disease. Regular brushing and flossing as you would your natural teeth will ensure that your crown will be in place for years to come!

Types of Tooth Crowns

Most dentists will agree that the tooth crown is at the heart of general dentistry. They've all studied dental crowns in dental school, and some have done their best work replacing a missing tooth and saving the rest.

Research has given them the wherewithal to achieve virtually ideal restorations. They are natural looking, comfortable and stable in the moist environment of the mouth. Cosmetic dentistry professionals are better equipped now more than ever to build strong, long-lasting and cosmetically superior dental crowns.

What is a dental crown?

A crown (or cap) is a restoration placed over broken teeth or a cracked tooth that cannot sustain a conventional filling. By covering the biting surfaces and sides of the tooth, a dental crown strengthens the damaged tooth by binding together the remaining structures. There are basically three kinds of full-crown restorations that can be placed by your cosmetic dentist, each with pros and cons, depending on your situation.

A gold crown or metal alloy crowns have the longest track record for durability, but some people object to the look of metal.

A full porcelain crown - and its new ceramic cousin - looks wonderful and fits well; however, porcelain crowns are usually best on front teeth where stress is not so great.

Porcelain-fused-to-metal dental crowns are our loyal work-horses for single-tooth restoration - they're very strong.

There are elements of finesse in the creation of any crown. The fit is the thing. The teeth must be prepared with opposing teeth in mind so a good bite won't go bad after the crown is placed. The fit must accommodate adjacent teeth, too. And the "margin," the part of the crown nearest the gum, must fit smoothly to protect the health of gum tissue.

And all this effort is to one end: to save a tooth.

When is a dental crown called for?

• A tooth that has been filled more than once cracks, breaks off, or falls victim to secondary caries - a cavity under or around a filling.
• You've had root canal treatment on a molar, and it's prone to brittleness.
• A tooth has suffered severe enamel wear.
• The high school hockey star takes a blow in the mouth, and an otherwise sound tooth is broken.
• You need an anchor for your new dental bridge.
