Dental restorations are not permanent. Anyone telling you otherwise is overselling. They last a long time when done properly and looked after, but every material has a lifespan.
Here is the realistic breakdown.
How long do fillings last?
Fillings depend heavily on material, bite force, and oral habits.
- Composite (white) fillings usually last 5 to 10 years. They look natural but wear faster, especially on molars.
- Amalgam (silver) fillings can last 10 to 15 years, sometimes longer, but they are used far less now.
Fillings fail most often because of decay creeping underneath or repeated stress from clenching and grinding.
How long do crowns last?
Crowns are stronger and more protective than fillings, but they are still not forever solutions.
Most crowns last 10 to 15 years. Some last 20 years or more with excellent care.
Their lifespan depends on:
- Oral hygiene
- Bite forces and grinding
- Gum health around the crown
Crowns usually fail due to decay at the edge, gum recession, or cracks from pressure.
How long do veneers last?
Veneers are cosmetic restorations, not structural ones.
Porcelain veneers typically last 10 to 15 years. Composite veneers often last closer to 5 to 7 years.
They are more sensitive to habits like nail biting, chewing ice, and teeth grinding. Veneers rarely fail suddenly. They chip, stain, or loosen over time.
What actually shortens the lifespan
Most restorations do not fail because of age alone. They fail because of:
- Inconsistent brushing and flossing
- Skipped dental checkups
- Grinding or clenching without protection
- High sugar or acidic diets
The work can be perfect. The environment still matters.
Fillings, crowns, and veneers are long-term repairs, not lifetime guarantees. They’re long-lasting solutions when placed well and cared for with consistent brushing, flossing, regular check-ups, and protection from habits like grinding.
If you want your fillings, crowns, or veneers to last as long as possible, book a check-up so we can tailor a maintenance plan that fits your mouth and habits. Our team at Dr. Salim Kapadia Dental Centre helps patients protect and extend the life of their dental work.
