Life-likeDentalPorcelainHelpsRestoreSmilesMarredbyUnattractiveTeeth

With its life-like color and texture, dental porcelain can restore a smile marred by decayed or damaged teeth. This durable ceramic material not only matches the varieties of individual tooth colors and hues, its translucence mimics the appearance of natural teeth. But perhaps its greatest benefit is its adaptability for use in a number of different applications, particularly veneers and crowns.

Veneers are thin layers of dental porcelain laminated together and permanently bonded to cover the visible outer side of a tooth to improve its appearance. Crowns, on the other hand, are “caps” of dental porcelain designed to completely cover a defective tooth.

Veneers and crowns share a number of similarities. Both can alter the color and shape of teeth, although crowns are used when more extensive tooth structure has been damaged. They’re also “irreversible,” meaning the tooth must be altered in such a way that it will always require a veneer or crown, though on some occasions a veneer can require no removal of tooth structure and can be reversible.

They do, however, have some differences as to the type of situation they address. Veneers are generally used where the affected teeth have a poor appearance (chipped, malformed or stained, for example) but are still structurally healthy. And although they do generally require some removal of tooth enamel to accommodate them (to minimize a “bulky” appearance), the reduction is much less than for a crown.

Crowns, on the other hand, restore teeth that have lost significant structure from disease, injury, stress-related grinding habits or the wearing effects of aging. Since they must contain enough mass to stand up to the normal biting forces a tooth must endure, a significant amount of the original tooth structure must be removed to accommodate them.

Which application we use will depend upon a thorough examination of your teeth. Once we’ve determined their condition and what you need, we can then recommend the best application for your situation. But regardless of whether we install a veneer or crown, using dental porcelain can help achieve an end result that’s truly life-changing — a new, younger-looking smile.

ACrownCouldbetheAnswertoPreservingYourDamagedTooth

We’ve been treating one of your decay-prone teeth for some time with one filling after another. Each incident required a little more removal of decayed tooth material until now there isn’t enough structure to support another filling.

We could remove the tooth and replace it with a bridge or a dental implant, both viable restoration options. But keeping the tooth if possible would be more beneficial in the long-run for your gums, bone and remaining teeth. If it still has a healthy and stable root, it’s possible to permanently cover or “cap” the tooth with a life-like crown.

Crowns have been used for decades: the first were mainly composed of metal like gold or silver and later dental porcelain, a ceramic material that could be molded, shaped and oven-fired to resemble a real tooth. The earliest porcelains, though, were brittle, so a hybrid with a metal interior for strength and a fused exterior porcelain layer for appearance came into prominence.

Today, advances in materials have led to all-porcelain crowns strong enough to withstand biting forces. While the metal-porcelain hybrid still account for about 40% of crowns installed annually, the all-porcelain types are steadily growing in popularity.

Regardless of the type, though, the process for fitting any crown is relatively the same. The first step is to reshape the affected tooth so that the future crown will fit over it, followed by an impression mold of the tooth a dental technician will use to form a custom crown. Once the new crown has been prepared, we then permanently bond it to the tooth.

With a crown, you’ll be able to enjoy normal function and have a tooth that looks as healthy and normal as its neighbors. Be aware, though, that your underlying tooth is still subject to decay — so diligent, daily hygiene and regular dental visits are a must. With proper care your newly crowned tooth can continue to serve you and your smile for many years to come.
