The average crown should last for 5-15 years. Some have even been known to last up to 25 years if they are well maintained.
5. Why do crowns fail?
Bite issues: One of the most common reasons that a crown fails is due to bite issues, especially in patients who grind or clench their teeth. Decay: Especially with older crowns, decay can become your worst enemy. The crown itself won’t decay or corrode, but your natural tooth underneath the crown is still vulnerable.
