What is the Life Span of a Dental Crown?
Posted by cyberanto on January 16, 2008
A dental crown, which restores a damaged tooth, can be made from three main materials: porcelain, gold or gold fused with porcelain.
Gold
Gold is the least aesthetic material because of its yellowish colour, but it is also very durable. A gold crown may last for up to 25-30 years, considering that good oral hygiene is maintained.
Porcelain
A porcelain crown is very beautiful; of all materials, it gives the most natural appearance to a tooth. Its life span is however the shortest, lasting almost 10 years.
Gold fused to porcelain
A crown made of gold fused to porcelain offers the aesthetics of porcelain and the strength of gold. Its longevity is around 15 years.
When a tooth is less destroyed by tooth decay, it can be restored using an onlay or inlay, which can also be made up on gold or porcelain.
