How long does a dental crown last?

90% of crowns should not require major treatment within five years, and 50 to 80% of crowns should last between 15 and 20 years.4 The life of your crown depends on how well you take care of it with your daily dental hygiene practices. It is advised to try to avoid chewing hard or sticky foods, which can cause your crown to break or come loose.

Common CDT codes for Crowns:

  • [2740] Crown - porcelain/ceramic substrate
