Composite Bonding vs
Dental Crowns
Not sure whether you need cosmetic bonding or a dental crown? Both improve the appearance and function of your teeth — but they are designed for very different clinical situations. The right choice depends on the condition of your tooth.

If your dentist has mentioned composite bonding or a dental crown, you may be wondering what the difference is and which option is right for your situation. The short answer: bonding is a cosmetic treatment that enhances appearance, while a crown is a restorative treatment that rebuilds and strengthens a damaged tooth.
Understanding the difference is important because the right treatment depends entirely on the clinical condition of your tooth — not personal preference alone. Choosing bonding when a crown is needed could leave a weakened tooth vulnerable to fracture. Equally, having a crown placed on a tooth that only needs minor cosmetic improvement would be unnecessarily invasive.
At Dental Clinic London, we offer both cosmetic and restorative treatments. Your dentist will assess your tooth and recommend the most appropriate, conservative option — always with your best interests in mind. Below, we compare both treatments so you can arrive at your consultation well informed.

Cosmetic Treatment
What Is Composite Bonding?
Composite bonding is a cosmetic dental treatment where tooth-coloured composite resin is applied directly onto the tooth surface by your dentist, sculpted by hand and polished to a natural finish. It is used to repair chips, close gaps, reshape uneven teeth, cover discolouration and improve the symmetry of your smile.
At Dental Clinic London, composite bonding is completed in a single visit — typically 30–60 minutes per tooth. In most cases, no drilling and no anaesthetic are needed because the composite is bonded directly to the natural enamel. This makes it one of the most conservative, affordable and reversible cosmetic treatments available.
Composite bonding costs from £395 per tooth at our clinic, with multi-tooth packages available (2 teeth from £790, 4 from £1,580, 6 from £2,370). A free 15-minute cosmetic consultation is available to discuss your options.
Composite Bonding Is Suitable For
- Chipped or worn front teeth
- Gaps between teeth (diastemas)
- Minor discolouration or staining
- Uneven tooth edges or shapes
- Teeth that are slightly too small or narrow
- Patients who want a reversible cosmetic improvement
Restorative Treatment
What Are Dental Crowns?
A dental crown — sometimes called a cap — is a custom-made restoration that covers the entire visible part of a tooth above the gum line. It restores the tooth's original shape, size, strength and appearance, allowing it to function like a natural tooth again.
Crowns are one of the most common and reliable treatments in general dentistry. They are used to protect teeth weakened by decay, fracture, root canal treatment or large fillings — and to improve the appearance of severely damaged or discoloured teeth.
At Dental Clinic London, all crowns are 100% metal-free and crafted from advanced dental ceramics. We offer three types: zirconia (from £995 — maximum strength), lithium disilicate / E.max (from £995 — most natural translucency) and layered porcelain / PFZ (from £1,195 — strength and aesthetics combined). Treatment typically requires two appointments spaced 1–2 weeks apart.
A Crown May Be Recommended When
- A tooth is weakened after root canal treatment
- A large portion of the tooth has broken or fractured
- An old, large filling has failed and the tooth is undermined
- Severe decay has destroyed significant tooth structure
- A tooth on a dental implant needs to be restored
- Cosmetic improvement of a severely damaged or discoloured tooth
Understanding the Difference
Key Differences Explained
Coverage and Strength
Composite bonding is applied to a specific area of the tooth surface — typically the front or edge. It improves appearance but does not add structural strength. A dental crown covers the entire tooth all the way around (360°), encasing and reinforcing it. For teeth that are cracked, weakened or heavily restored, only a crown provides the full-coverage protection needed to prevent fracture.
Tooth Preparation
Composite bonding usually requires no tooth preparation at all — no drilling, no anaesthetic. The composite is applied directly to the natural enamel. A dental crown requires the tooth to be reshaped under local anaesthetic, with approximately 1.5–2 mm of tooth structure removed all around to create space for the crown. This preparation is irreversible — once a tooth is crowned, it will always need a crown.
Longevity
Composite bonding typically lasts 5–10 years with good care. It can stain over time and may chip under heavy biting forces. Dental crowns are significantly more durable — zirconia and layered porcelain crowns routinely last 15–25+ years, while E.max porcelain crowns last 10–20 years. For long-term durability, crowns are the superior option.
Cost
Composite bonding is more affordable — from £395 per tooth at Dental Clinic London. Dental crowns start from £995 (zirconia or E.max) and £1,195 for layered porcelain. Bonding is completed in one visit with no laboratory costs. Crowns require laboratory fabrication, which contributes to the higher price. 0% finance is available on both treatments, subject to status.
Suitability Based on Damage
This is the most important clinical distinction. Composite bonding is suitable for teeth that are structurally sound but have minor cosmetic imperfections — chips, gaps, discolouration, uneven edges. A crown is needed when the tooth has significant structural damage — after root canal treatment, when large portions have broken away, or when decay has undermined the tooth. Your dentist will assess which is clinically appropriate.

Making Your Decision
Which Option Is Best for You?
The most appropriate treatment depends on the clinical condition of your tooth and your goals. Here is a general guide — your dentist will confirm the best approach following examination.
Best for Minor Cosmetic Corrections
Composite Bonding · From £395If your teeth are structurally sound but you want to fix chips, close small gaps, even out edges or cover minor discolouration, composite bonding is the ideal choice. It is minimally invasive, affordable, completed in a single visit and completely reversible. No tooth structure needs to be removed.
Best for Heavily Damaged Teeth
Dental Crown · From £995If your tooth has been weakened by root canal treatment, a large fracture, severe decay or a failed filling, a dental crown provides the full-coverage structural support needed to prevent further damage. Only a crown can encase and reinforce the entire tooth — bonding cannot restore structural integrity.
Best for Long-Term Durability
Dental Crown · From £995If longevity is your priority, dental crowns are the more durable option. Zirconia and layered porcelain crowns routinely last 15–25+ years, compared to 5–10 years for composite bonding. Crowns are also more resistant to staining and chipping.
Best for Affordability
Composite Bonding · From £395Composite bonding is significantly more affordable — from £395 per tooth compared to £995+ for a crown. It is also completed in a single visit with no laboratory costs. For patients looking for a cost-effective cosmetic improvement, bonding offers excellent value.
For patients considering a broader aesthetic transformation, both treatments can form part of a smile makeover plan. Veneers may also be an alternative worth discussing with your dentist.
