Dental Crown vs Filling: When Do You Need a Crown?
Last updated:
A filling repairs a small amount of damage. A crown replaces the entire outer surface.
Both fillings and crowns restore damaged teeth — but they are designed for different levels of damage. Understanding the difference helps you make an informed decision.
When a filling is enough
- Small to moderate cavities (less than half the tooth width)
- Minor chips that do not affect tooth structure
- The remaining tooth structure is strong enough to support a filling
Fillings are quicker (20-30 minutes), cheaper (NHS Band 2: 73.50 pounds), and preserve more natural tooth. Read: NHS charges explained.
When you need a crown
- Large cavities where more than half the tooth is damaged
- After root canal treatment (the tooth becomes brittle)
- Cracked or fractured teeth that a filling cannot hold together
- Severely worn teeth (from grinding or erosion)
- Teeth with multiple large existing fillings that keep failing
A crown covers the entire visible tooth above the gum line, providing strength and protection. It takes 2 appointments and costs NHS Band 3: 319.10 pounds. Private crowns cost 400-1,000 pounds depending on material.
Crown materials
| Material | Best for | Appearance | Durability |
|---|---|---|---|
| Metal (gold/silver) | Back teeth | Metallic | Excellent (20+ years) |
| Porcelain-fused-to-metal | Any tooth | Good (can show metal line) | Very good (10-15 years) |
| All-ceramic/zirconia | Front teeth, aesthetics | Excellent (natural look) | Very good (10-15 years) |
