On average, a dental crown lasts about 10β15 years β and many last 20+ years with good care. π¦·β¨
What affects how long it lasts
- Material
- Porcelain / ceramic: ~10β15 years (great looks, a bit more fragile)
- Porcelain-fused-to-metal (PFM): ~10β20 years
- Gold / metal: often 20+ years (least likely to crack)
- Zirconia: ~15β20+ years (very strong, newer but promising)
- Where it is
- Back teeth take more force β may wear sooner
- How you use it
- Grinding or clenching (bruxism)
- Chewing ice, hard sweets, pens π¬
- Oral hygiene
- Crowns donβt decay, but the tooth underneath can
Common reasons crowns fail
- Decay at the edge of the crown
- Cement wearing down β crown loosens
- Cracks or chips
- Heavy grinding without a night guard
How to make a crown last longer
- Brush twice daily + floss (especially around the crown edge)
- Avoid chewing super-hard foods on it
- Wear a night guard if you grind
- Regular dental checkups
One important thing:
If a crowned tooth starts hurting, thatβs not normal long-term and could mean:
- Decay under the crown
- A cracked tooth
- Nerve irritation or infection
Thatβs usually fixable β but the sooner itβs checked, the better.
