Dental crowns are a common solution for restoring damaged teeth, offering both cosmetic and functional benefits. Whether you have a tooth that is cracked, weakened, or cosmetically flawed, a dental crown can provide the protection and aesthetic improvement you need. However, not all dental crowns are created equal. Different materials are used to make crowns, each with its own set of advantages and ideal applications. In this post, we’ll explore the various types of dental crowns available, their specific uses, and what you should consider when choosing the right crown for your dental needs.
1. Porcelain-Fused-to-Metal (PFM) Crowns
Porcelain-fused-to-metal (PFM) crowns have been a popular choice for many years due to their combination of strength and aesthetic appeal. These crowns consist of a metal base covered with a layer of porcelain, which mimics the appearance of natural teeth.
Advantages:
- Strength: The metal base provides excellent durability, making PFM crowns ideal for back teeth where the forces of chewing are the strongest.
- Aesthetic Appeal: The porcelain layer is designed to match the color of your natural teeth, providing a more aesthetic result compared to all-metal crowns.
Disadvantages:
- Metal Exposure: Over time, the metal beneath the porcelain may become visible, especially at the gum line, which can affect the crown’s appearance.
- Wear on Opposing Teeth: The porcelain surface can be abrasive to opposing teeth, potentially causing wear over time.
Best Uses: PFM crowns are typically recommended for patients who need a balance of strength and aesthetics, especially in cases where the crown will be placed on a molar or premolar. If you’re looking for dental crowns in Phoenix that offer durability while maintaining a natural look, PFM crowns might be an excellent choice.
2. All-Ceramic or All-Porcelain Crowns
All-ceramic or all-porcelain crowns are made entirely from ceramic or porcelain material, providing the most natural appearance among the various types of crowns. These crowns are often chosen for their superior aesthetics and compatibility with gum tissue.
Advantages:
- Natural Appearance: All-ceramic crowns offer the closest match to natural tooth color, making them an excellent choice for front teeth or visible areas.
- Biocompatibility: These crowns are metal-free, reducing the risk of allergic reactions or irritation to the gums.
Disadvantages:
- Less Durable: All-ceramic crowns are generally less durable than metal-based crowns and are more prone to chipping or cracking, especially on back teeth.
- Cost: These crowns tend to be more expensive due to the materials and craftsmanship involved.
Best Uses: All-ceramic or all-porcelain crowns are ideal for patients who prioritize aesthetics and have no significant issues with grinding or clenching their teeth. They are particularly suitable for restoring front teeth or any teeth that are highly visible when you smile.
3. Gold Crowns
Advantages:
- Durability: Gold crowns are incredibly strong and resistant to wear, making them one of the longest-lasting crown options available.
- Biocompatibility: Gold crowns are gentle on the opposing teeth and have excellent biocompatibility with gum tissue.
- Less Tooth Reduction: Less natural tooth structure needs to be removed when placing a gold crown compared to other types.
Disadvantages:
- Aesthetic Concerns: The most significant drawback of gold crowns is their appearance. The metallic color is noticeable and may not be desirable for visible teeth.
- Cost: Gold crowns can be more expensive due to the cost of the materials.
Best Uses: Gold crowns are most commonly used for molars or other teeth that are not visible when you smile. They are a great option for patients who need a durable, long-lasting solution and are less concerned with the aesthetics of the crown.
4. Zirconia Crowns
Zirconia crowns are a relatively new option in the world of dental restorations, offering a blend of strength and aesthetics. Made from zirconium dioxide, these crowns are incredibly strong and can be color-matched to your natural teeth.
Advantages:
- Strength: Zirconia is one of the strongest materials used in dental crowns, making it highly resistant to chipping and cracking.
- Aesthetics: These crowns can be made to closely match the color of your natural teeth, providing a pleasing appearance.
- Biocompatibility: Zirconia crowns are metal-free and well-tolerated by the gums, reducing the risk of allergic reactions.
Disadvantages:
- Cost: Zirconia crowns tend to be more expensive than other types of crowns due to the advanced technology and materials used.
- Potential Wear on Opposing Teeth: Although strong, zirconia can cause wear on opposing teeth if not polished properly.
Best Uses: Zirconia crowns are versatile and can be used for both front and back teeth. They are particularly useful for patients who need a strong, durable crown that also provides a natural appearance.
5. Resin Crowns
Resin crowns are made from composite resin, the same material used for tooth-colored fillings. These crowns are less commonly used due to their lower durability compared to other materials.
Advantages:
- Cost: Resin crowns are generally more affordable than other types of crowns, making them an option for patients on a budget.
- Aesthetic Match: Resin crowns can be color-matched to your natural teeth, providing a reasonably aesthetic result.
Disadvantages:
- Durability: Resin crowns are not as durable as other types, making them more prone to wear, chipping, and discoloration over time.
- Shorter Lifespan: These crowns typically need to be replaced more frequently than other types.
Best Uses: Resin crowns are usually recommended for temporary use or for patients who need an economical solution. They are less suitable for long-term restoration due to their lack of durability.
6. Temporary Crowns
Temporary crowns are used as a short-term solution while a permanent crown is being fabricated. These crowns are typically made from acrylic or stainless steel and are not intended to last more than a few weeks.
Advantages:
- Protection: Temporary crowns protect the prepared tooth and maintain the space for the permanent crown.
- Affordability: Since they are temporary, these crowns are made from less expensive materials.
Disadvantages:
- Durability: As the name suggests, temporary crowns are not durable and can break or become dislodged easily.
- Aesthetics: Temporary crowns are usually less aesthetically pleasing compared to permanent options.
Best Uses: Temporary crowns are an essential part of the dental crown process, serving as a placeholder until the permanent crown is ready. They are used for all types of crown preparations, regardless of the material of the final crown.

Choosing the right type of dental crown depends on various factors, including the location of the tooth, your aesthetic preferences, budget, and the specific dental issue being addressed.
