Even if you’re 60 years old and your gold crowns are half that age, you do not need to replace them simply to avoid more problems and replacements in later years.
That said, a crown, which resembles a thimble that covers a tooth, needs to be well fitted, with no open margins and no decay around the margins. Gold doesn’t corrode, but after three decades, the cement holding the crown in place is susceptible to dissolution by saliva.
Replacing a crown is not just a matter of cost. Every time a dentist puts in a crown or a filling, some damage is done to the pulp so some teeth that were crowned may eventually require a root canal.
Even so, if a crown needs to be replaced because of decay or bad contours, the additional loss of tooth structure by the drilling is negligible, versus no treatment. Gold crowns are made of cast gold, a technique that has been in existence for over a hundred years. Cast gold crowns have no match with regard to long-term service and minimal wear to opposing teeth. They may ultimately fail because of predictable wear of the metal , and because of decay.
