What Types of Dental Crowns Are There

When it comes to dental crowns, there are several different types available, each with its own unique advantages and considerations. From traditional metal crowns to modern all-ceramic options, the choice depends on various factors including aesthetics, durability, and cost. In this article, we will explore ten different types of dental crowns in detail, discussing their characteristics, average prices, and popular applications.

1. Metal Crowns

Metal crowns, often made from gold or silver alloys, have been used in dentistry for many years. Their strength and longevity make them a popular choice for molars and premolars. These crowns can withstand heavy biting forces and are less prone to chipping or breaking. On the downside, their metallic color may not be appealing to everyone, particularly for visible teeth. The average cost of metal crowns ranges from $800 to $1500.

However, it is essential to note that metal crowns can cause galvanic reactions in the mouth when paired with other metal restorations. This can result in discomfort or an unpleasant taste. Additionally, allergy to metal alloys may be a concern in some individuals.

2. Porcelain-Fused-to-Metal (PFM) Crowns

Porcelain-fused-to-metal crowns are a popular choice due to their ability to combine aesthetics with durability. These crowns have a metal substructure covered with a layer of porcelain to mimic the appearance of natural teeth. The metal provides strength, while the porcelain provides a tooth-colored finish. PFM crowns are commonly used for both front and back teeth.

The average cost of porcelain-fused-to-metal crowns ranges from $800 to $1600. However, it is important to consider that the porcelain layer may wear down over time, resulting in a visible metal margin. Additionally, the underlying metal may cause a darker line to appear at the gumline, compromising the aesthetics.

3. All-Ceramic Crowns

All-ceramic crowns have gained popularity in recent years due to their excellent aesthetic properties. These crowns are made entirely of ceramic or porcelain material, offering a natural and translucent appearance that closely mimics real teeth. They are an ideal choice for highly visible teeth, such as front incisors.

The cost of all-ceramic crowns varies depending on the specific type of ceramic used and the dental clinic. On average, the price ranges from $900 to $2500. However, their increased aesthetic value comes with a potential trade-off in terms of durability. All-ceramic crowns may be more prone to fracture or chipping compared to metal or PFM crowns.

4. Zirconia Crowns

Zirconia crowns are a type of all-ceramic crown that offers excellent strength and durability. These crowns are made from zirconium dioxide, a biocompatible material known for its high resistance to fracture and wear. Zirconia crowns can withstand biting forces and are less likely to chip or crack.

The average cost of zirconia crowns ranges from $1000 to $2500. They are frequently used for both front and back teeth due to their translucent appearance and superior strength. However, zirconia crowns may be more abrasive to opposing teeth compared to other types of crowns.

5. E-Max Crowns

E-Max crowns are a popular choice for patients seeking maximum aesthetics. They are made from a single block of lithium disilicate ceramic, which provides strength and lifelike translucency. E-Max crowns are known for their ability to blend seamlessly with natural teeth, making them a preferred option for front teeth restorations.

The average cost of E-Max crowns ranges from $1000 to $3000. While they offer excellent aesthetics, E-Max crowns may not be as strong as zirconia or metal crowns, and they may be more prone to fracture.

6. Gold Crowns

Gold crowns, although not as popular as other options due to their appearance, offer outstanding longevity and biocompatibility. They are made from gold alloys, ensuring excellent durability and resistance to wear. Gold crowns are commonly used for molars, where their strength is essential.

The average cost of gold crowns ranges from $1000 to $2500. However, the higher cost of gold and the demand for specialized dental expertise make them a more expensive option compared to other crowns.

7. Ceramic Crowns with a Metal-Free Substructure

Ceramic crowns with a metal-free substructure provide a combination of aesthetics and strength. They are made from materials like zirconia and alumina oxide, known for their durability and biocompatibility. The absence of metal eliminates the potential for galvanic reactions or allergic responses.

The average cost of ceramic crowns with a metal-free substructure ranges from $1000 to $2500. These crowns can be used for both front and back teeth, offering a reliable and natural-looking restoration.

8. Temporary Crowns

Temporary crowns are typically made from acrylic or stainless steel and are used as a provisional restoration while waiting for a permanent crown. They are not meant to last for an extended period and are intended to protect the prepared tooth from sensitivity and damage.

The cost of temporary crowns varies depending on the material used, but they are generally significantly cheaper than permanent crowns. Temporary crowns serve as a temporary solution until the final crown is ready to be placed.

9. Composite Resin Crowns

Composite resin crowns are a relatively new option that offers natural-looking results without the need for extensive tooth preparation. They are made from a tooth-colored resin material that is directly bonded to the tooth. Composite resin crowns are best suited for situations where preservation of tooth structure is a priority.

The average cost of composite resin crowns ranges from $800 to $1500. However, it is essential to consider that they may be more prone to wear and staining compared to other types of crowns.

10. Temporary Stainless Steel Crowns for Children

Temporary stainless steel crowns are commonly used for children who require crowns on baby teeth. These crowns are preformed and can be easily placed over the tooth to provide protection and restoration. They are cost-effective and designed to last until the baby tooth is naturally exfoliated.

The cost of temporary stainless steel crowns for children is around $200 to $600 per crown.

Frequently Asked Questions (FAQs)

Q: How long do dental crowns typically last?

A: The longevity of dental crowns depends on various factors, including oral hygiene, bite forces, and material used. On average, dental crowns can last between 10 to 15 years with proper care.

Q: Are dental crowns painful to get?

A: The process of getting dental crowns is generally not painful as local anesthesia is used to numb the area. However, some post-operative sensitivity may be experienced initially.

Q: Can dental crowns be whitened?

A: Dental crowns made from materials like metal or porcelain-fused-to-metal cannot be whitened. However, all-ceramic crowns, especially those made from newer materials, have a higher resistance to staining and discoloration.

Q: How can I maintain the longevity of my dental crown?

A: To maintain the longevity of your dental crown, it is essential to practice good oral hygiene, including regular brushing, flossing, and dental check-ups. Additionally, avoiding excessive biting forces and refraining from using your teeth as tools can help preserve your crown.
