Understanding Dental Caps and Crowns
Restoring a damaged tooth often involves the use of a dental crown or cap, a procedure that is both restorative and cosmetic in nature. Dental crowns are custom-made to encase the entire visible portion of a tooth above the gumline, serving multiple purposes in maintaining oral health.
The primary function of a dental crown is to restore tooth functionality and aesthetics. By encasing a damaged tooth, a crown protects it from further damage and improves its appearance, allowing patients to chew and smile with confidence.
Are Dental Caps and Crowns Different?
The terms ‘dental cap’ and ‘crown’ are often used interchangeably in dentistry. Essentially, they refer to the same dental restoration. The confusion arises from the terminology, with ‘cap’ sometimes being associated with a less invasive procedure. However, in modern dentistry, a dental crown or cap is a tooth-shaped covering that is cemented over a damaged tooth.
| Terminology | Description |
|---|---|
| Dental Cap/Crown | A custom-made covering for a damaged tooth |
| Purpose | Restorative and cosmetic enhancement |
Definition and Purpose
A dental crown is designed to mimic the appearance of a natural tooth while providing strength and protection to the underlying tooth structure. The purposes of a dental crown include strengthening a weak tooth, protecting a cracked tooth, restoring a worn-down or broken tooth, holding a dental bridge in place, covering a severely stained or discoloured tooth, covering a root canal-treated tooth, and covering a dental implant.
Dental crowns are made from various materials, including metal, porcelain-fused-to-metal, and all-ceramic or porcelain. The choice of material depends on the tooth‘s location, the extent of the damage, and the patient’s preferences regarding appearance and durability.
When Would You Need a Dental Cap or Crown?
The need for a dental cap or crown arises from several dental concerns, ranging from restoring damaged teeth to enhancing the overall appearance of one’s smile.
Restorative Purposes
Dental crowns are often used for restorative purposes, such as covering a tooth that has been damaged due to decay or trauma. They can also be used to support a dental bridge or cover a dental implant. In some cases, a crown may be necessary to protect a weak tooth from further damage or to restore a tooth that’s been broken or worn down.
Cosmetic Purposes
In addition to their restorative uses, dental crowns can also be used for cosmetic purposes. For instance, they can be used to cover severely stained or discoloured teeth that don’t respond to traditional whitening treatments. Cosmetic crowns can also be used to correct the appearance of misshapen, worn, or irregularly sized teeth, creating a more harmonious smile. Furthermore, they can be used to close small gaps between teeth or correct minor alignment issues without the need for orthodontic treatment.
Cosmetic crowns are carefully designed to match the colour, translucency, and texture of surrounding natural teeth for a seamless appearance. When considering a cosmetic option, it’s essential to weigh the benefits of crowns against other available choices, such as veneers, to determine the most suitable solution for individual needs.
Types of Dental Crowns
Dental crowns are not a one-size-fits-all solution; various types are designed to meet specific requirements. The choice of crown depends on several factors, including the tooth’s location, the patient’s budget, aesthetic requirements, and functional demands.
Metal Crowns
Metal crowns are made from various metals, such as gold, silver, or other alloys. They are known for their durability and resistance to wear. One of the key advantages of metal crowns is their ability to withstand heavy forces, making them suitable for teeth that are subject to significant stress, such as molars.
Porcelain-Fused-to-Metal (PFM) Crowns
Porcelain-fused-to-metal crowns combine the strength of metal with the aesthetic appeal of porcelain. The metal base provides durability, while the porcelain layer on top enhances the crown’s appearance, making it more natural-looking. This blend of materials makes PFM crowns a popular choice for teeth that are visible when smiling.
All-Ceramic or Porcelain Crowns
All-ceramic or porcelain crowns are made entirely from ceramic materials, offering excellent aesthetic properties. They are ideal for teeth that are visible, as they can be matched to the surrounding teeth. However, they may not be as durable as other types of crowns.
All-Resin and Other Crown Types
All-resin crowns are made from resin and are generally less expensive than other types of crowns. However, they are more prone to breaking and typically last between three to five years. Dentists often use resin to make temporary crowns while waiting for the permanent crown to be fabricated. Advances in technology have also led to the development of CAD/CAM same-day crowns, which use computer-aided design and manufacturing to create ceramic crowns in a single appointment.
The various types of dental crowns available mean that patients have a range of options to suit their specific needs, whether it’s for restorative or cosmetic purposes. Factors such as durability, aesthetics, and cost play a significant role in determining the most appropriate type of crown.
- All-resin crowns are a more affordable option but are less durable.
- Temporary crowns are often made from resin to protect prepared teeth.
- CAD/CAM technology allows for same-day ceramic crowns.
- The choice of crown material depends on several factors, including tooth location and patient budget.
The Dental Crown Procedure Explained
The process of getting a dental crown involves several steps, from initial consultation to the final placement of the permanent crown. Understanding this procedure can help patients feel more comfortable and informed throughout their treatment.
Initial Consultation and Tooth Preparation
The journey to receiving a dental crown begins with an initial consultation with a dentist. During this visit, the dentist assesses the tooth’s condition to determine if a crown is necessary. If so, the tooth is prepared by removing any decay or damaged areas and shaping it to accommodate the crown. This preparation stage is crucial for ensuring the crown fits properly and functions as expected.
After preparation, impressions of the tooth are taken and sent to a laboratory where the permanent crown is fabricated. This process typically takes a couple of weeks.
Temporary Crowns vs Permanent Crowns
While waiting for the permanent crown, a temporary crown is placed over the prepared tooth to protect it from further damage or decay. Temporary crowns are made of acrylic or stainless steel and are less durable than their permanent counterparts. They are designed to be a short-term solution, maintaining the tooth’s position and aesthetics until the final crown is ready.
In contrast, permanent crowns are custom-made to match the natural teeth and are designed to be long-lasting. They are fabricated in a dental laboratory using materials such as porcelain, ceramic, or metal. Once the permanent crown is ready, the temporary crown is removed, and the dentist checks the fit of the permanent crown, making any necessary adjustments before cementing it into place.
| Crown Type | Material | Durability | Purpose |
|---|---|---|---|
| Temporary Crown | Acrylic or Stainless Steel | Less Durable | Short-term protection |
| Permanent Crown | Porcelain, Ceramic, or Metal | Highly Durable | Long-term restoration |
Same-day CAD/CAM crowns differ from traditional crowns by eliminating the need for temporaries and multiple appointments. Using advanced technology, the dentist can design and fabricate the crown in a single visit, providing patients with a more streamlined experience.
Dental Caps vs Crowns: Comparing Materials
Dental crowns are made from various materials, each with its own set of advantages and disadvantages. The choice of material significantly influences the crown’s durability, aesthetic appeal, and overall performance.
Durability Comparison
The durability of dental crowns varies depending on the material used. Metal crowns, for instance, are known for their strength and longevity, making them a suitable option for molars that are subject to heavy chewing forces. In contrast, all-ceramic or porcelain crowns, while aesthetically pleasing, may not be as durable as their metal counterparts.
A comparison of the durability of different crown materials reveals that:
- Metal crowns are highly durable and resistant to wear.
- Porcelain-fused-to-metal (PFM) crowns offer a balance between durability and aesthetics.
- All-ceramic crowns are more prone to chipping but provide excellent aesthetic results.
Aesthetic Considerations
The appearance of dental crowns is a critical factor, especially for crowns placed on front teeth. All-ceramic or porcelain crowns are highly valued for their ability to mimic the natural appearance of tooth enamel. They offer superior aesthetics due to their translucency and light-reflecting properties.
In terms of aesthetics, the key considerations include:
- The material’s ability to match the surrounding teeth in colour and translucency.
- The potential for gum recession to expose the crown’s margin.
- The impact of the crown material on the overall appearance of the smile.
Porcelain-fused-to-metal (PFM) crowns, while offering good initial aesthetics, may develop a visible dark line at the gumline over time as gums recede. In contrast, all-porcelain crowns maintain their aesthetic appeal without the risk of metal showing through.
Cost and Insurance Considerations
The financial implications of opting for dental crowns can be complex, involving both costs and insurance considerations. When contemplating this restorative option, it’s crucial to understand the factors that influence the overall expense.
Factors Affecting Crown Costs
The cost of a dental crown is not uniform and can vary based on several factors. These include the material used for the crown, the complexity of the procedure, and the expertise of the dentist. For instance, crowns made from high-quality ceramic or porcelain tend to be more expensive than those made from metal or a combination of materials. Additionally, the location and reputation of the dental clinic can also impact the final cost.

Insurance Coverage for Dental Crowns
Dental insurance may cover crowns that are deemed medically necessary, but the extent of coverage can vary significantly. In the UK, both NHS and private insurance providers have different policies regarding dental crowns. Generally, insurance policies categorise crowns as major restorative procedures, covering 50-70% of the costs up to the annual maximum. However, purely cosmetic applications are typically not covered.
It’s essential for patients to consult with their dentist and insurance provider to understand the pre-authorisation requirements and the approval process. Moreover, discussing alternative payment options, such as dental discount plans, payment plans, and healthcare financing options like those offered by CareCredit and LendingPoint, can help make the treatment more affordable.
Lifespan and Durability of Dental Crowns
The longevity of dental crowns can vary significantly based on the material used and patient care. Dental crowns are designed to be durable, but their lifespan depends on several factors, including the type of material, oral hygiene practices, and the presence of any underlying dental issues.
How Long Do Dental Crowns Last?
Dental crowns can last for many years when properly cared for. On average, a well-maintained crown can last between 10 to 30 years. Proper care includes regular brushing, flossing, and dental check-ups. The material used for the crown also plays a significant role in its longevity. For instance, crowns made from porcelain or ceramic tend to last longer than those made from resin.
Signs of Wear and When to Replace
Recognising the signs of wear and tear on dental crowns is essential for maintaining optimal oral health. Common signs include chipped or cracked crowns, which can occur due to trauma or biting hard objects. You might also notice the crown becoming loose or dislodged, caused by decay below the crown or cement failure. Discoloration or dark lines at the gum line, particularly with porcelain-fused-to-metal (PFM) crowns, can also indicate wear.
- Chipped or cracked crowns, which can occur due to trauma or biting hard objects.
- Loose or dislodged crowns, often caused by decay below the crown or cement failure.
- Discoloration or dark lines at the gum line, particularly with PFM crowns.
- Sensitivity or discomfort in the crowned tooth, suggesting the crown no longer fits properly.
| Signs of Wear | Description | Possible Cause |
|---|---|---|
| Chipped or Cracked Crowns | Visible damage to the crown | Trauma or biting hard objects |
| Loose or Dislodged Crowns | Crown becomes loose or falls off | Decay below the crown or cement failure |

If you notice any of these signs, it’s crucial to schedule an appointment with your dentist. Prompt attention can prevent further complications, such as tooth decay or infection under the crown.
Care and Maintenance of Dental Crowns
The longevity of dental crowns depends significantly on how well they are cared for and maintained. Proper care not only extends the life of the crown but also ensures the overall health of the surrounding teeth and gums.
Daily Oral Hygiene Practices
Maintaining good oral hygiene is crucial for the longevity of dental crowns. This includes brushing teeth at least twice a day with fluoride toothpaste to remove plaque and bacteria that can lead to decay or gum disease. It’s also important to clean between the teeth and around the crown margins daily using interdental brushes or floss to prevent the accumulation of plaque and tartar.
Avoiding sticky foods that can dislodge or damage the crown is also advisable. Foods like caramel, toffee, or chewing gum can be particularly problematic.
Professional Care and Regular Check-ups
Regular dental check-ups are essential for monitoring the condition of dental crowns. During these visits, dentists can assess the integrity of the crown, checking for signs of wear, damage, or decay at the margins. Professional cleanings are also vital as they remove hardened tartar that cannot be eliminated through home care alone, thus helping to maintain the crown’s longevity.
| Care Practice | Benefit |
|---|---|
| Brushing twice a day with fluoride toothpaste | Removes plaque and bacteria, reducing the risk of decay and gum disease |
| Interdental cleaning | Prevents plaque and tartar buildup around the crown margins |
| Regular dental check-ups | Allows for early detection of issues with the crown, such as wear or damage |
By combining good daily oral hygiene practices with regular professional care, individuals can significantly extend the life of their dental crowns and maintain overall oral health.
