Comparison · Additive repair vs full coverage
Bonding vs crowns: which repair fits the damage.
Bonding adds material to the tooth; a crown covers what is left. For a small chip, bonding is the better tool. For a tooth that has lost a lot of structure, a crown is the stronger and more predictable repair.
Planning ranges, not quotes. See the methodology.
| Dental bonding | Dental crown | |
|---|---|---|
| Cost per tooth | $100 – $600 (avg ~$431) | $800 – $2,500 (porcelain avg ~$1,399) |
| Appointments | One | Two (plus any root canal or build-up) |
| Tooth removal | Little or none | 1–2mm all around |
| Typical lifespan | 3 – 10 years | 10 – 15+ years |
| Strength | Good for small repairs | Protects the whole tooth |
| Best for | Chips, small gaps, local stains | Large damage, root canal, cracks |
Cost ranges are published US planning ranges, updated November 2026. Crowns are priced by material: resin or temporary crowns are at the low end, porcelain and porcelain-fused-to-metal in the middle.
When bonding is enough
Bonding is the right tool when the damage is small and the remaining tooth is strong. A chipped corner, a narrow gap, a stained patch or a slightly misshapen edge can be repaired in one visit with little or no enamel removal. The result is usually reversible, and the cost is a fraction of a crown.
When a crown is the better repair
A crown is the better repair when a large amount of the tooth is missing, when the tooth has had root canal treatment, when a crack extends below the gum, or when a large filling has weakened the walls of the tooth. A crown covers and protects what is left, so it is much less likely to fracture under heavy biting force.
A crown is also used after a root canal, when the tooth has become brittle, and when the remaining structure is not enough to hold a filling or bonding reliably.
Why the choice is not just about price
A crown costs more upfront, but it also removes more tooth and usually needs two appointments. A crown that fails often needs a new crown; bonding that fails can often be patched. On the other hand, placing bonding on a tooth that has lost a lot of structure can lead to a fracture, a failed repair and a crown anyway.
The right choice is the one that matches the amount of damage, the tooth position and the bite. A dentist should be able to explain why one option fits your tooth and the other does not.
Questions to ask before you choose
- How much healthy tooth structure is left?
- Is the tooth cracked, and does the crack extend below the gum?
- Has the tooth had root canal treatment?
- What is the expected lifespan for my tooth and my habits?
- What happens if the repair fails — patch, replace or crown?
Common questions
Is dental bonding cheaper than a crown?
Yes. Bonding averages about $431 per tooth, while a crown typically runs $800–$2,500, per Aflac and CareCredit. A porcelain crown averages about $1,399 and a porcelain-and-metal crown about $1,114.
When is a crown necessary instead of bonding?
A crown is usually needed when a large amount of tooth structure is missing, when the tooth has had root canal treatment, when a crack extends below the gum, or when a large filling has weakened the remaining tooth. Bonding cannot restore that much missing structure.
Which lasts longer, bonding or a crown?
A crown usually lasts longer — typically 10–15 years or more, compared with 3–10 years for bonding. A crown also covers and protects the whole tooth, so it is stronger under heavy biting force.
How much tooth is removed for a crown?
A crown requires preparing the tooth on all sides and the biting surface, usually removing 1–2mm of structure so the crown has room. That removal is permanent. Bonding usually removes little or no enamel.
Can a crown be placed on a front tooth?
Yes. Front-tooth crowns are usually all-ceramic or porcelain for appearance. They are used when the damage is too large for bonding or a veneer, such as a root-canal-treated front tooth or a large fracture.
