A dental crown is a tooth-shaped cap that is cemented over a tooth to restore its size, shape, and function. This dental prosthetic is fitted onto a tooth and fully encases it, providing the tooth with support and stability.
Why is a Crown Needed?
A dental crown may be needed for several reasons:
Types of Dental Crowns
Dental crowns can be temporary or permanent. At Sabeti Cosmetic Dentistry, crowns can be made from a wide range of materials.
Stainless Steel Crown
Stainless steel crowns are temporary crowns that are used on adults while they are waiting for their permanent crown to be manufactured. For children, stainless steel crowns are used to protect a primary tooth from further decay. The crown covers the entire tooth and comes out when the baby tooth falls off.
Stainless steel crowns are used as they are quite affordable and do not require multiple visits to the dentist.
Metal crowns contain a high amount of gold, platinum, or cobalt-chromium and nickel-chromium alloys. These crowns are extremely strong and durable and can withstand a lot of pressure. Their main drawback is their metallic color, so they are usually not preferred on the incisors or canine teeth. However, they are perfect for restoring teeth.
Meta crowns can last for 20 to 40 years, depending on the material and your oral care regimen.
Porcelain-fused-to-metal crowns consist of a metal base covered by a layer of porcelain. These crowns are quite strong and natural-looking. They are also stain-resistant. However, the porcelain part of the crown can wear away with time. Additionally, they can wear down your opposing teeth.
You may also detect a thin dark line at your gumline, which is the dark underlying metal showing through. This can become more prominent if your gums recede. These crowns are a great option to support bridges and to restore both front and back teeth.
All-porcelain or all-ceramic crowns are the most natural-looking type of crowns as they almost exactly match the color of your teeth. These crowns are also great for people who have metal allergies. Because they look like your real teeth, many people choose to restore their incisors and canines with these crowns. However, their main drawback is that they are not as strong and do not last as long as metal-based crowns.
All-resin crowns are the least expensive types of crown. They are quite natural-looking and are good for repairing front teeth. However, they are prone to more wear and tear and are also not as stain-resistant as porcelain.
How Long Do Crowns Last?
How long a crown lasts depends on the material it is made of, the wear and tear it is exposed to, your lifestyle habits (like teeth grinding, chewing on very hard substances, smoking, and biting fingernails) and oral hygiene regimen.
Dental crowns can last for an average of 15 years. Gold crowns, which are the most durable type of crowns, are known to last for over 40 years!
