Dental crowns typically last between 10 and 30 years, depending on factors such as the material used, oral hygiene, diet, and wear and tear
. Lifespan by material:
- Gold crowns can last 20 years or more, sometimes even a lifetime, due to their durability, but they are less commonly used because of cost
- Porcelain crowns generally last 5 to 15 years, though with good care, they may last longer. They are more prone to chipping compared to metal crowns
- Porcelain-fused-to-metal (PFM) crowns last about 10 to 15 years, combining durability with aesthetics
- Ceramic crowns can last up to 15 years with proper care
- Zirconia crowns are among the strongest and can last 15 to 20 years or more due to high resistance to chipping
- Resin crowns tend to last 5 to 10 years and are more prone to wear and discoloration
Factors influencing crown longevity:
- Good oral hygiene (brushing twice daily, flossing, regular dental check-ups) can extend crown life
- Avoiding hard foods and habits like teeth grinding or using teeth as tools helps prevent damage
- Crowns placed on front teeth may last longer due to less chewing pressure
- Crowns may need replacement if they become loose, cracked, or if decay develops underneath
In summary, with proper care, most dental crowns last between 10 and 30 years, but individual results vary based on material and lifestyle habits
