If a tooth is chipped, worn, or damaged, two of the most common treatments are composite bonding and dental crowns. Both can restore appearance and function — but they work in very different ways.
Bonding is typically a cosmetic solution for minor imperfections, while crowns provide full structural restoration for weakened or heavily damaged teeth. The right choice depends on the condition of your tooth and what you need to achieve.
This guide compares both treatments to help you understand the key differences. The most appropriate option will always depend on a clinical assessment by your dentist.
| Feature | Composite Bonding | Dental Crowns |
|---|---|---|
| Primary Purpose | Cosmetic improvement | Structural restoration |
| Coverage of Tooth | Partial — applied to surface | Full — covers entire tooth |
| Strength | Moderate | High |
| Durability | 5–10 years | 10–25 years |
| Aesthetic Result | Natural, tooth-coloured | Natural, custom-matched shade |
| Treatment Time | 30–60 minutes per tooth | 2 appointments over 1–2 weeks |
| Cost (Per Tooth) | From £197.50 (member) / £395 | From £497.50 (member) / £995 |
| Longevity | 5–10 years with care | 10–25+ years with care |
| Tooth Preparation | Minimal to none | Moderate reduction required |
| Best Suited For | Chips, gaps, minor reshaping | Cracked, weakened, or heavily filled teeth |

Composite bonding is a cosmetic dental treatment in which a tooth-coloured composite resin is applied directly to the surface of a tooth. It is shaped and polished to blend seamlessly with your natural teeth.
It is commonly used to repair minor chips, close small gaps between teeth, reshape uneven edges, or cover surface discolouration. The treatment is minimally invasive and is usually completed in a single appointment, typically taking 30–60 minutes per tooth.
Composite bonding is most suitable for patients with minor cosmetic concerns — small chips, slight gaps, uneven tooth edges, or mild discolouration. It is ideal for those who want a conservative, reversible treatment that preserves as much natural tooth structure as possible.
A dental crown is a custom-made restoration that completely covers a damaged or weakened tooth. It is designed to restore the tooth's shape, size, strength, and appearance — functioning as a protective cap over the existing structure.
Crowns are commonly recommended after root canal treatment, for teeth with large fillings, cracked or fractured teeth, and teeth that are too damaged for bonding or fillings alone. They are available in porcelain, zirconia, and metal-ceramic materials.
Dental crowns are most appropriate for patients with structurally compromised teeth — those with large fillings, cracks, fractures, or teeth that have undergone root canal treatment. They are also used when a tooth requires both functional restoration and cosmetic improvement.
Composite bonding is primarily a cosmetic treatment for surface-level improvements. Crowns provide full structural restoration, reinforcing a weakened or damaged tooth from all sides.
Crowns are significantly stronger than composite bonding. Porcelain and zirconia crowns can withstand greater biting forces and are less prone to chipping over time.
Bonding requires minimal to no tooth preparation — the resin is applied directly to the enamel. Crowns require moderate reduction of the natural tooth to accommodate the restoration.
With proper care, crowns typically last 10–25 years. Composite bonding usually lasts 5–10 years and may require periodic repair or replacement.
Both treatments provide natural-looking results. Bonding is shaped and polished chairside, while crowns are custom-fabricated in a laboratory for precise shade and contour matching.
Composite bonding starts from £197.50 per tooth for members (£395 non-members). Dental crowns — including porcelain and zirconia options — start from £497.50 for members (£995 standard). Membership halves the cost of both treatments.
Costs vary depending on the complexity of treatment, the number of teeth involved, and the materials used. Below are our current prices.

Composite bonding is generally more affordable in the short term, though crowns may offer better long-term value for teeth that require structural restoration. Final costs depend on your individual treatment plan.
If you have minor chips, small gaps, or uneven edges, composite bonding offers a quick, conservative solution with natural-looking results.
Composite BondingFor teeth with significant decay, large fillings, fractures, or after root canal treatment, a crown provides the structural support needed.
Dental CrownIf preserving your natural tooth structure is a priority, bonding requires little to no enamel removal and is fully reversible.
Composite BondingIf you need a restoration that will last 15–25+ years with minimal maintenance, a zirconia or porcelain crown is the more durable option.
