Dental Crown vs Filling: What Is the Difference?
Fillings repair small areas of decay. Crowns cover the entire tooth.
| Feature | Dental Filling | Dental Crown |
| Coverage Area | Repairs only the decayed or damaged portion of the tooth | Covers and protects the entire visible portion of the tooth |
| Tooth Strength | Provides moderate reinforcement for minor structural loss | Offers full structural reinforcement for weakened or fractured teeth |
| Durability | Typically lasts 5–10 years, depending on the material and bite pressure | Often lasts 10–15+ years with proper care and maintenance |
| Best For | Small to moderate cavities with sufficient remaining tooth structure | Large cavities, cracked teeth, root canal-treated teeth, or severe wear |
| Protection Level | Restores shape but leaves remaining enamel exposed | Seals and shields the tooth from further fracture or bacterial invasion |
| Cost Range | Lower initial cost | Higher initial investment with longer lifespan |
| Bite Stability | Limited support for heavy chewing forces | Designed to withstand strong chewing pressure and restore bite balance |
When significant tooth structure is lost, a dental crown provides superior long-term stability, protection, and functional support compared to a filling.
