How Long Do Crowns Last?
Dental Crowns are prosthetic devices formed in the shape of a tooth. These prosthetics are used to cover up a tooth that has weakened due to infection, injury, lifestyle habits, or surgery. At JP Dental & Implant Center, Dr. John P. Poovey and Dr. Wilcox we recommend the use of dental crowns to protect and strengthen a particularly vulnerable tooth and to restore its functionality.
Depending on the type of material it is made from, a dental crown may last from a few years to a few decades.
What Type of Dental Crowns Last the Longest?
Dental crowns are made in a variety of materials based on where they need to be placed. The most common types of material include metal-based crowns, porcelain-crowns, and all-resin crowns.
Gold crowns are the strongest and most durable dental crowns. Gold is a hypoallergenic material which means it does not cause adverse reactions when it comes into contact with human tissue. It also is very corrosion-resistant and does not break down over time. Because of its strength and its metallic color, gold crowns are usually placed on the back teeth.
Gold crowns have a lifespan of over 25 years, though they have been known to last for up to 40 years.
Base-metal crowns are made from an alloy of nickel, chromium, and cobalt, or a combination of these. Since they are very strong, they are also preferred for back teeth. However, some people may be allergic to certain metals like nickel.
These crowns are much less expensive than gold alloy crowns but are very durable. Most base metal crowns can last for up to 25 years.
Porcelain-fused-to-metal crowns are made of a metal base that is covered by a shell of porcelain. These crowns are more real-looking than only-metal crowns and may be a good option for front and back teeth.
Even though the porcelain used in the crown is of high grade, it may become fractured or chipped if too much pressure is exerted on it. However, it can easily be fixed.
Porcelain-fused-to-metal crowns can last for over 15 years if you exercise proper care with them.
Porcelain crowns are the most natural-looking and esthetically pleasing out of all crowns. Porcelain reflects light which makes it appear like real enamel. In addition, porcelain is highly resistant to stain and does not corrode. That is why many people prefer porcelain crowns for their front teeth.
However, porcelain crowns are almost as expensive as gold alloy crowns. Plus, porcelain is not as strong as metal-based crowns and is prone to cracking and chipping. Hence, it can last for up to 10 years.
These crowns are made of composite resin, a mixture of plastic and glass. All-resin crowns are white and quite natural-looking. In addition, they are also much cheaper than porcelain crowns. Hence, they are a good alternative for repairing front teeth.
However, all-resin crowns are the weakest of all crowns and can chip over time. They are also not very stain-resistant. On average, these crowns can last anywhere between three to seven years, depending on their level of care.
Stainless Steel Crown
Stainless steel crowns are not permanent crowns, like the ones above, but are only used on a temporary basis. These crowns are most commonly used to protect baby teeth from decay. When your child’s baby tooth falls out, this crown will also fall off with it.
In addition, stainless steel crowns are also used to protect adult teeth after they have endodontic surgery. This crown can be used to prevent damage to an adult tooth and restore its chewing ability while the client is waiting for their permanent crown to be fabricated.
As you can see, there are several different types of crowns and their life expectancy is based on the material and level of care given to them.
