What Are Dental Crowns Made Of?

Dental crowns are a common solution for restoring damaged teeth, providing both functional and aesthetic benefits. But what exactly are they made of? Dental crowns can be crafted from various materials, including:

• Porcelain
• Ceramic
• Metal
• A combination of more than one of these.

Whether you are considering a dental crown for cosmetic reasons or to protect a weakened tooth, understanding the different materials used, along with their advantages and disadvantages, can help you make an informed decision that best suits your dental needs and lifestyle.

What are Dental Crowns?

Dental crowns, often referred to as caps, are a type of dental restoration that completely encases a damaged or decayed tooth. Crowns are used to:

• Strengthen the tooth
• Restore its shape and size
• Improve its overall appearance

They are vital tools in modern dentistry, addressing both functional and aesthetic concerns.

Dental crowns can be made from several materials, each offering unique benefits and drawbacks. These materials range from metals to ceramics, and the choice depends on various factors including durability, aesthetic appeal, and cost.

Porcelain Crowns

Porcelain crowns are highly popular due to their natural appearance. They mimic the translucency and colour of natural teeth, making them an excellent choice for front teeth.

Porcelain is biocompatible, which means it does not cause allergic reactions. However, porcelain crowns are less durable than some other materials and may chip or crack over time.

Advantages & Disadvantages of Porcelain Crowns

One significant advantage of porcelain crowns is their ability to match the colour of surrounding teeth. This makes them ideal for patients who prioritize aesthetics.

On the downside, they can be more expensive and may require more tooth reduction compared to other types of crowns.

Metal Crowns

Metal crowns are known for their durability and strength. They are typically made from alloys that contain a high content of metals such as gold.

These crowns can withstand significant biting and chewing forces, making them suitable for molars and other back teeth. While they are long-lasting, their metallic colour can be a drawback for those seeking a more natural look.

Advantages & Disadvantages of Metal Crowns

The longevity of metal crowns is one of their most significant advantages. They rarely chip or break and require less tooth removal compared to other crown types.

However, their metallic appearance can be less appealing, especially for visible teeth.

Porcelain-Fused-to-Metal (PFM) Crowns

Porcelain-fused-to-metal crowns combine the strength of metal with the natural appearance of porcelain.

These crowns have a metal core for durability and a porcelain exterior for aesthetics. PFM crowns are versatile and can be used for both front and back teeth.

Advantages & Disadvantages of PFM Crowns

PFM crowns offer a good balance between strength and aesthetics. They are more durable than all-porcelain crowns and provide a natural look.

However, over time, the porcelain layer can wear down or chip, revealing the underlying metal.

Ceramic Crowns

Ceramic crowns are similar to porcelain crowns but are made entirely of ceramic material. They offer a natural appearance and are suitable for patients with metal allergies.

Ceramic crowns are often used for front teeth due to their aesthetic appeal. However, they may not be as durable as metal-based crowns.

Advantages & Disadvantages of Ceramic Crowns

The natural look of ceramic crowns makes them a popular choice for visible teeth. They are also biocompatible and do not cause allergic reactions.

However, they may be more prone to chipping and cracking, especially when used on back teeth.

What to Consider When Choosing Crown Materials

When selecting the material for a dental crown, several factors need to be considered. These include durability and strength, aesthetic appeal, cost considerations, and compatibility with natural teeth.

Durability & Strength

The durability and strength of the crown material are crucial, especially for molars that endure significant biting and chewing forces. Metal crowns are known for their strength and longevity. 

On the other hand, porcelain and ceramic crowns, while aesthetically pleasing, may not be as durable as metal-based crowns.

Aesthetic Appeal

For visible teeth, aesthetic appeal is a significant consideration. Porcelain and ceramic offer a natural appearance that can be colour-matched to surrounding teeth. PFM crowns also provide a good balance of aesthetics and strength.

Metal crowns may not be suitable for visible teeth due to their metallic appearance.

Cost Considerations

The cost of dental crowns can vary significantly depending on the material used. Metal crowns, are generally more affordable than porcelain and ceramic.

Patients should consider their budget and the longevity of the crown material when making a decision. Investing in a more durable material may save money in the long run by reducing the need for replacements.

Compatibility with Natural Teeth

Compatibility with natural teeth is another important factor to consider. Some patients may have allergies or sensitivities to certain metals, making metal crowns less suitable.

Porcelain and ceramic crowns are biocompatible and less likely to cause allergic reactions.

Patients should discuss any known allergies or sensitivities with their dentist to ensure the chosen crown material is safe and compatible with their natural teeth.

Finding the Best Option for Your Dental Needs

Your dentist’s recommendation is a crucial factor in choosing the right crown material. Dentists consider various factors, including the location of the tooth, the patient’s bite, and any known allergies or sensitivities.

Trusting your dentist’s expertise and discussing your concerns and preferences can help ensure that you choose a material that meets your needs and expectations. Whether you prioritize aesthetics, durability, or cost, there is a dental crown material that can meet your requirements.
