Differences Between Dental Crowns and Veneers: A Comprehensive Guide
Dental crowns and veneers are popular restorative and cosmetic dental procedures used to improve the appearance and function of teeth. Despite their similarities in purpose, they differ significantly in application, material, and functionality. This guide will explore these differences in detail, providing a thorough understanding for dental professionals and informed patients.
1. Definition and Purpose
Dental Crowns:
- Definition: Dental crowns, also known as caps, are prosthetic devices that cover the entire tooth. They are used to restore a tooth’s shape, size, strength, and appearance.
- Purpose: Crowns are typically used to protect weakened teeth, restore broken or severely worn-down teeth, cover and support teeth with large fillings, hold dental bridges in place, cover misshaped or severely discoloured teeth, and cover dental implants.
Veneers:
- Definition: Dental crowns, also known as caps, are prosthetic devices that cover the entire tooth. They are used to restore a tooth’s shape, size, strength, and appearance.
- Purpose: Crowns are typically used to protect weakened teeth, restore broken or severely worn-down teeth, cover and support teeth with large fillings, hold dental bridges in place, cover misshaped or severely discoloured teeth, and cover dental implants.
2. Material and Durability
Dental Crowns:
- Material: Crowns can be made from a variety of materials, including metal (such as gold or palladium), porcelain fused to metal (PFM), all-ceramic, or all-resin.
- Durability: Crowns are highly durable and can last between 10 to 15 years, depending on the material and the patient’s oral hygiene practices. Metal crowns tend to be the most durable, followed by PFM and all-ceramic.
Veneers:
- Material: Veneers are typically made from porcelain or composite resin.
- Durability: Porcelain veneers are more durable and can last 10 to 15 years, while composite veneers last around 5 to 7 years. Both types require good oral hygiene to maximize their lifespan.
3. Procedure and Tooth Preparation
Dental Crowns:
- Procedure: The process involves shaping the entire tooth to allow the crown to fit over it. This often requires reducing the tooth’s size significantly.
- Preparation: Multiple visits are usually necessary. The first visit involves tooth preparation, impression taking, and fitting a temporary crown. The second visit involves fitting and cementing the permanent crown.
Veneers:
- Procedure: Veneer placement requires minimal tooth preparation. The dentist removes a small amount of enamel from the front and sides of the tooth to make room for the veneer.
- Preparation: Veneers typically require two visits. The first visit includes tooth preparation and impression taking, while the second visit involves bonding the veneer to the tooth.
4. Coverage and Extent of Restoration
Dental Crowns:
- Coverage: Crowns cover the entire tooth, providing comprehensive protection and restoration.
- Extent of Restoration: Crowns are suitable for extensive restoration needs, such as after a root canal treatment or for teeth that are heavily decayed or fractured.
Veneers:
- Coverage: Veneers cover only the front surface of the tooth.
- Extent of Restoration: Veneers are ideal for cosmetic improvements and minor restorative needs, such as covering discolouration, minor chips, or gaps between teeth.
5. Cost
Dental Crowns:
- Cost: Crowns are generally more expensive than veneers, with costs varying based on the material used. The average cost ranges from £600 to £2,000 per tooth.
Veneers:
- Cost: Veneers can also be costly, particularly porcelain veneers, which range from £600 to £1,600 per tooth. Composite veneers are less expensive, ranging from £200 to £1,200 per tooth.
6. Aesthetics and Appearance
Dental Crowns:
- Aesthetics: Crowns, particularly porcelain and all-ceramic types, can be made to match the colour of adjacent teeth. However, metal crowns are more noticeable.
- Appearance: Crowns provide a natural appearance, especially when made from porcelain or ceramic materials.
Veneers:
- Aesthetics: Veneers are highly aesthetic and are designed to match the natural colour and translucency of teeth. Porcelain veneers, in particular, offer excellent mimicry of natural teeth.
- Appearance: Veneers provide an enhanced cosmetic appearance, making teeth look uniformly white and well-shaped.
Conclusion
Choosing between dental crowns and veneers depends on the specific dental issue and the desired outcome. Crowns are more suitable for significant restoration and protection, while veneers are ideal for cosmetic enhancements. Both options offer unique benefits and considerations in terms of material, durability, procedure, coverage, cost, and aesthetics. Consulting with a dental professional can help determine the best choice based on individual needs and circumstances.

What are Crowns? Your FAQs answered
1. What is a dental crown?
A dental crown is a custom-made tooth-shaped cap that is placed over a damaged or decayed tooth to restore its shape, size, strength, and appearance.
2. Why would I need a dental crown?
Dental crowns are used to protect weak teeth, restore broken or severely decayed teeth, support dental bridges, cover dental implants, and improve the aesthetics of discoloured or misshapen teeth.
3. How long do dental crowns last?
On average, dental crowns can last between 10 to 15 years or even longer with proper care and maintenance.
4. Are there different types of dental crowns?
Yes, dental crowns can be made from various materials, including porcelain, metal (gold or silver), porcelain-fused-to-metal (PFM), and all-ceramic (all-porcelain or zirconia).
5. Which type of dental crown is the best?
The choice of the best dental crown material depends on several factors, including the location of the tooth, aesthetic preferences, and the patient’s budget. Your dentist will help you decide the most suitable option.
6. Is the process of getting a dental crown painful?
The procedure to get a dental crown is generally not painful. Local anaesthesia is used to numb the area during tooth preparation to ensure comfort.
7. How long does it take to get a dental crown?
The process typically requires two visits to the dentist. The first appointment involves tooth preparation and taking impressions, while the second appointment is for the placement of the permanent crown.
8. Are dental crowns noticeable?
Modern dental crowns are designed to match the colour and shape of your natural teeth, making them virtually indistinguishable from the surrounding teeth.
9. Can I eat normally with a dental crown?
Yes, once the crown is firmly in place, you can eat normally. However, it’s essential to avoid biting into very hard objects to prevent damage to the crown.
10. How do I take care of a dental crown?
Regular oral hygiene practices, including brushing, flossing, and using mouthwash, are essential for maintaining your dental crown’s longevity. Additionally, regular dental check-ups are necessary to ensure the crown’s condition.
11. Can dental crowns fall off?
While rare, dental crowns can come loose or fall off, especially if there’s significant tooth decay or damage. If this occurs, contact your dentist immediately.
12. Will getting a dental crown change the way my bite feels?
In some cases, getting a dental crown might slightly alter your bite temporarily. However, your dentist will ensure that the crown’s fit is accurate and comfortable.

In some cases, it’s possible to get a dental crown after treating gum disease. However, your dentist will need to evaluate your oral health before proceeding.
19. Can dental crowns fix crooked teeth?
Dental crowns are primarily used for restorative purposes. To fix crooked teeth, orthodontic treatments like braces or clear aligners are more appropriate.
20. Do dental crowns require any special maintenance?
Dental crowns don’t require specific maintenance beyond regular oral hygiene practices. However, avoid habits like teeth grinding, nail-biting, or using your teeth to open packages, as these can damage the crown.
