Deciding between a crown vs filling is a common crossroads for our patients in Manchester and Leeds. When you have a cavity or a broken tooth, the goal is always the same: restore the function of your bite and stop the pain. However, the “right” choice depends entirely on the extent of the damage.
At Night and Day Emergency Dentist, we see patients across the North of England who are unsure if a simple patch is enough or if they need more substantial protection. Whether you’ve lost a filling in Leeds or have a sudden crack in Manchester, here is your guide to choosing the best restorative treatment.

To understand the choice of crown vs filling, it helps to look at how each one supports your tooth:
- Dental Filling:
- Used for minor decay or small chips.
- The material (composite resin or silver) is “packed” into a hole.
- Relies on the remaining natural tooth walls for support.
- Dental Crown:
- A custom-made “cap” that covers the entire visible part of the tooth.
- Used when the tooth is too weak to hold a filling.
- Protects the tooth from fracturing under pressure.
Crown vs Filling: The Comparison Table
| Feature | Dental Filling | Dental Crown |
|---|---|---|
| Extent of Damage | Small to medium cavities. | Large cracks, breaks, or root canals. |
| Structural Support | Relies on existing tooth walls. | Provides 360-degree protection. |
| Procedure Time | Single visit (approx. 30–60 mins). | Usually two visits (prep + fitting). |
| Durability | 5 to 10 years on average. | 15+ years with proper care. |
| Invasiveness | Minimal; only decay is removed. | Requires shaping the tooth for the cap. |
| Typical Cost | Lower initial cost. | Higher investment due to lab fees. |
The “Rule of Thumb”: When a Crown is Necessary
A common industry standard is the “Rule of Thirds.” If a cavity or old filling takes up more than 1/2 to 1/3 of the tooth’s width, a filling is no longer safe.
- The Wedge Effect: A large filling acts like a wedge. Every time you bite down, it pushes outward against your thin tooth walls. Eventually, those walls will snap.
- Root Canal Protection: After a root canal, the tooth becomes brittle. A crown is essential to keep it from shattering.
- Cracked Tooth Syndrome: If you feel a sharp pain when you release your bite, you likely have a crack that only a crown can “splint” together.
- Extreme Wear: Patients in Manchester and Leeds who suffer from bruxism (grinding) often need crowns to restore height and prevent further erosion.
When to Choose a Filling vs. a Crown
When a Filling is Best:
- Small Cavities: If the decay hasn’t spread to more than 50% of the tooth.
- Minor Chips: Repairing a small edge of a front tooth.
- Preserving Enamel: When you want to keep as much of your natural tooth as possible.
When a Crown is Necessary:
- After a Root Canal: The tooth becomes brittle and requires a crown for strength.
- Large Old Fillings: If an old filling falls out and takes a piece of the tooth with it.
- Cracked Tooth Syndrome: When a crack is deep enough to cause pain but hasn’t reached the root.
- Severe Discolouration: When a tooth is badly stained and doesn’t respond to teeth whitening.
