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.

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.
