How Long Do Dental Crowns Last? Tips for Longevity
Dental Crowns BridgesA dental crown is a durable, long-term solution for restoring a damaged tooth. But 'long-term' doesn't necessarily mean 'forever.' While crowns are built to withstand the immense pressure of chewing, they are not indestructible.
The Average Lifespan
On average, a dental crown lasts between **10 and 15 years**. However, this is just a baseline. With excellent care, it is not uncommon for crowns to last 25 years or even a lifetime. Conversely, poor hygiene or bad habits can cause a crown to fail in less than 5 years.
Factors That Affect Longevity
- Material: Gold and Zirconia crowns are generally stronger and less likely to chip than porcelain-fused-to-metal or pure porcelain crowns.
- Oral Hygiene: The tooth *under* the crown can still get cavities. If decay starts at the gumline, the crown will lose its seal and fail.
- Bite Forces: Grinding or clenching your teeth (bruxism) puts excessive force on the crown, leading to cracks or loosening.
How to Make Your Crown Last
Treat your crown like a high-value asset. To extend its life:
- Wear a Night Guard: If you grind your teeth at night, a custom guard is the best insurance policy for your crown.
- Avoid Hard Foods: Chewing on ice, hard candy, or opening packages with your teeth can fracture the porcelain.
- Floss Daily: This is non-negotiable. You must remove plaque from the base of the crown to prevent decay at the margin.
