A well-made crown or bridge, with proper oral hygiene and regular check-ups, can be a stable, aesthetic and well-functioning solution for many years. The expected lifespan depends on the material, the condition of the tooth or abutment tooth, the bite, teeth grinding, home cleaning and regular dental check-ups.
In general, metal-ceramic crowns can in many cases work well for 10–15 years or longer. Zirconia and pressed ceramic crowns, with the right indication and careful fabrication, can also be a long-lasting solution.
The lifespan of a bridge depends not only on the chosen material, but also on the condition of the abutment teeth. If the teeth under or next to the bridge decay, the gums weaken, or the restoration cannot be cleaned properly, this can also affect the durability of the bridge.
If you grind or clench your teeth, wearing a night guard may be recommended to protect the crown, the bridge and your own teeth.
