Dental crowns are one of the most popular and best treatments to restore the appearance and functionality of damaged teeth. Whether you have a broken tooth, a cavity too large for a filling, or you’ve had a root canal, crowns can be a game-changer. But with so many crowns available, how can you know which one is ideal for you?
In this article, we’ll walk you through the numerous types of crowns for teeth, their materials, and how to choose the perfect one for your smile.
What is a Dental Crown?
- A dental crown is a cap or cover placed over a tooth to restore shape, size, strength, and look. Crowns are typically used to: • Restore a severely decaying tooth.
- Protect a weak tooth from shattering or to hold together fragments of a broken tooth.
- Cover and support a tooth with a big filling when there isn’t enough dental structure.
- Cosmetically enhance a discolored or malformed tooth.
- Complete a dental implant.
Crowns come in a range of materials and designs, and the appropriate one for you will rely on various aspects, such as the location of the tooth, your tastes, and your dentist’s suggestions.
Types of Crowns for Teeth
Dental crowns can be classed by material and purpose. Let’s look at each type in greater detail:
1. Temporary Crowns:
These are temporary solutions used while creating a permanent crown. They are often composed of acrylic or a comparable substance.
Temporary crowns protect a tooth while a permanent crown is manufactured.
Advantages: Quick and cost-effective solution to safeguard teeth until permanent crowns are ready.
Disadvantages: Temporary crowns are easily loosened, so avoid hard meals and brush gently.
2. Traditional crowns.
- Traditional crowns are the most popular type of dental crown. They necessitate two dental visits: one to prepare the tooth and the other to bond the permanent crown.
- Material options include porcelain, ceramic, metal alloys, or a combination.
- Used for severely damaged or decaying teeth, particularly back teeth.
- Advantages include durability and effectiveness in restoring dental function.
- Disadvantages: Requires enamel removal from the original tooth and can take a few weeks to receive a permanent crown.
3. CEREC Crowns (Same Day Crowns)
• What they are: Same-day crowns are manufactured at your dentist’s office with a CAD/CAM milling machine, eliminating the need for a second appointment.
• Materials used: Typically made of ceramic or porcelain.
• Used for patients who require a crown immediately and prefer not to undergo many appointments or temporary crowns.
• Advantages: Convenience of receiving a crown in a single visit, usually within hours.
• Disadvantages: Not all crowns are available in this format, and material choices may be limited compared to traditional crowns.
4. Onlays (Three-Quarter Crowns)
• Onlays cover a portion of a tooth, keeping more of the natural tooth structure than full crowns.
• When Used: For teeth with considerable but not complete damage, they provide strength while keeping a natural appearance.
• Advantages: More conservative than complete crowns, preserving more of the natural tooth.
• Disadvantages: Not as durable as complete crowns, especially with intense bite pressures.
Crown Types Based on Material
Depending on your requirements, different materials have distinct advantages. The following are the most commonly used materials for dental crowns:
5. Metal Crowns (Gold & Alloy):
Made from gold, palladium, or other alloys, these crowns are highly durable.
• Recommended for rear teeth with high pressure, such as molars.
• Advantages include high durability, resistance to wear, and low fracture rate.
• Disadvantages: Unappealing appearance due to their prominent placement in the mouth. Frequently used for molars where appearance is not an issue.
6. Porcelain Crowns:
These crowns are made entirely of porcelain and blend in flawlessly with natural teeth, providing a natural appearance.
• Suitable for front teeth or noticeable teeth when smiling.
• Advantages: Exceptional aesthetics and natural appearance.
• Disadvantages: Not as sturdy as metal crowns and more susceptible to chipping.
7. Crowns made from porcelain fused to metal (PFM)
• These crowns feature a metal base and a porcelain exterior.
• Used for front and back teeth, they combine metal’s strength with porcelain’s beauty.
• Advantages: Stronger than all-porcelain crowns while maintaining a natural appearance.
• Disadvantages: The metal base may show through at the gum line, especially if gums recede.
8. Resin Crowns: Made from composite resin, they are the most cost-effective type of crown.
• Used for tiny voids or interim solutions.
• Advantage: Cost-effective.
• Disadvantages: Low durability, prone to wear and fracture.
9. Zirconia crowns.
• They are made of zirconia, a highly durable ceramic substance.
• Used for both front and back teeth, offering a mix of aesthetics and strength.
• Advantages include high durability, fracture resistance, and cosmetic appeal compared to metal crowns.
• Disadvantages: Higher cost compared to other crown styles.
10. E-Max crowns (lithium disilicate)
• What they are: Made of lithium disilicate glass-ceramic material, which is noted for its durability and attractiveness.
• When They Are Used: This thin, long-lasting solution is ideal for front and back teeth.
• Advantages include excellent aesthetics and durability against chewing pressures.
• Disadvantages: Higher cost than typical porcelain or metal crowns.
Choosing the Ideal Crown for Your Smile
Selecting the best crown depends on several factors:
• Natural-looking materials like porcelain or E-Max are recommended for front teeth, while metal or zirconia are more durable for back teeth.
• For an aesthetically pleasing crown, porcelain or zirconia may be the best option.
• Metal or zirconia crowns are more durable and provide long-lasting wear.
• Cost considerations: Resin crowns are less expensive but may not be as durable as other materials.
