What is the Life Span of a Dental Crown?

January 16, 2008 cyberanto Leave a comment Go to comments

A dental crown, which restores a damaged tooth, can be made from three main materials: porcelain, gold or gold fused with porcelain.

Dental CrownGold
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.

    Question, is it common to have tooth decay under a gold crown or bridge? If so, how is this determined? How do you determine if a crown or bridge needs to be replaced? Thanks.

      Glynn,

      When a crown is very well sealed on a tooth that doesn’t have decay the day it was put on, then the chances of getting a new decay are low. Of course, someone who has bad hygiene, or bad nutrition can get that tooth decayed after a few years.

        Thanks for the reply.My gold bridge is over 20 years old and seems fine in my mouth (no issues). By using a probe, my dentist is saying she can feel some decay around the margin.The hygenist did not mention anything during the exam/cleaning session. Would this show up on an xray? I have no apparent problems and don’t want to replace it, if not necessary. I don’t want to rely on her word alone. Do you recommend a second opinion, or an xray to confirm what I am being told. It sounds like a bit of a dentist sell job, to be honest. Your reply is much appreciated!
