Crowns don't come with an expiration date. Many crowns can last a very long time but there are many factors which need to be considered. First, the quality of the crown and the technique used to place it are very important in determining the longevity of a crown. Next there are other risk factors which can also effect how long a crown lasts. Diet, medications and overall health come into play. Do you have gum disease? This could also be a factor. An evaluation of how long dental work has lasted in your mouth previously can be an indicator as to how long your new crown will last.
