Choosing the Right Dental Crown: Materials, Techniques, and Considerations

by:Golden Promise     2024-05-02


When it comes to dental crowns, making the right choice is crucial to ensure not only the longevity of your dental restoration but also your oral health. With an array of materials and techniques available, it is essential to understand the different options and considerations before deciding on the most suitable dental crown for your unique needs. This article will explore the various materials, techniques, and important factors to consider when choosing a dental crown, helping you make an informed decision and achieve optimal dental outcomes.

Different Materials for Dental Crowns

One of the first considerations when choosing a dental crown is the material from which it is made. Different materials offer varying levels of strength, aesthetics, durability, and affordability. Here are some commonly used materials for dental crowns:

1. Metal Crowns:

Metal crowns, typically made from alloys containing gold, platinum, or base metal alloys, are known for their exceptional strength and durability. These crowns are highly resistant to wear and tear, making them ideal for molars and teeth that undergo significant biting forces. Metal crowns also have a long lifespan and minimal risk of chipping or fracturing. However, due to their metallic color, metal crowns may not be a suitable choice for visible areas of the mouth.

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

PFM crowns combine the strength of metal with the aesthetic appeal of porcelain. The crown's inner layer consists of a metal substructure, providing durability and support, while the outer layer is made of tooth-colored porcelain to match the natural teeth. PFM crowns offer excellent aesthetics and are often used for front and back teeth. However, the porcelain layer may wear over time, and some patients may experience a dark line at the gum line as the metal substructure becomes visible.

3. All-Ceramic Crowns:

All-ceramic crowns are entirely metal-free and provide the most natural-looking result. They are commonly made of materials like zirconia or porcelain. These crowns have excellent aesthetics, resembling the color, translucency, and texture of natural teeth. All-ceramic crowns are a popular choice for highly visible teeth and patients with metal allergies. However, while advancements in materials have made all-ceramic crowns increasingly durable, they may not be as strong as metal or PFM crowns, making them less suitable for teeth exposed to heavy biting forces.

4. Composite Resin Crowns:

Composite resin crowns are a more affordable option that can be color-matched to blend seamlessly with natural teeth. They are made directly in the dental office and require a single visit for placement. Although composite resin crowns offer good aesthetics and moderate durability, they are more prone to chipping, staining, and wear compared to other materials. As a result, they are often considered a temporary solution or used for children with primary teeth.

5. Ceramic Crowns:

Ceramic crowns, also known as porcelain crowns, are made entirely of ceramics without any metal substructure. They offer excellent aesthetics and are an ideal choice for front teeth and patients with metal allergies. Ceramic crowns are highly biocompatible and provide a natural appearance due to their translucent properties. However, they are not as strong as other materials and may be more prone to chipping or cracking, especially on molars or teeth subjected to heavy biting forces.

Factors to Consider

Choosing the right dental crown goes beyond just selecting a material. Several factors should be taken into account to ensure the best possible outcome. Here are some crucial considerations when deciding on a dental crown:

1. Strength and Durability:

Assessing the strength and durability of the crown material is essential, especially for teeth involved in heavy chewing and biting. Molars typically require stronger materials to withstand the forces exerted during chewing, while front teeth may prioritize aesthetics over sheer strength.

2. Aesthetics:

Consider the appearance of the dental crown, especially for visible teeth. Crowns made from all-ceramic, porcelain, or porcelain-fused-to-metal can closely match the color, translucency, and texture of natural teeth, resulting in a more natural-looking smile.

3. Biocompatibility:

Some individuals may have allergies or sensitivities to certain metals. In such cases, all-ceramic or ceramic crowns are an excellent choice as they are metal-free and highly biocompatible.

4. Longevity:

The lifespan of a dental crown depends on various factors, including the material's durability, oral hygiene practices, and biting forces applied. While metal crowns tend to have the longest lifespan, all-ceramic and porcelain-fused-to-metal crowns offer exceptional longevity with proper care.

5. Cost:

Cost can be a significant consideration when choosing a dental crown. The price varies depending on the material selected and the complexity of the case. It is important to discuss cost considerations with your dentist and ensure that the chosen crown aligns with your budget.

Choosing the Right Technique

In addition to the material, the technique used to fabricate and place the dental crown plays a crucial role in the overall success of the restoration. Here are some common techniques used for dental crown placement:

1. Traditional Fabrication:

Traditional crown fabrication involves two separate dental visits. During the first appointment, the dentist prepares the tooth, takes impressions, and places a temporary crown. The impressions are sent to a dental laboratory, where skilled technicians fabricate the permanent crown based on the provided specifications. In the second visit, the temporary crown is removed, and the permanent crown is permanently cemented in place.

2. Same-Day Crowns:

With advancements in technology, some dental offices offer same-day crown placement using computer-aided design and computer-aided manufacturing (CAD/CAM) systems. The dentist takes digital impressions of the prepared tooth, which are then used to create a virtual model of the crown. The crown is milled from a block of dental material in the dental office, and it can be placed in the same visit, eliminating the need for a temporary crown and a second appointment.

3. Implant-Supported Crowns:

In situations where a dental implant is used to replace a missing tooth, an implant-supported crown is often the preferred option. The crown is custom-made to attach securely to the dental implant post, providing a functional and aesthetically pleasing restoration.


Choosing the right dental crown involves careful consideration of multiple factors, such as material, strength, aesthetics, and durability. Consulting with your dentist and discussing your specific needs and concerns will help guide you toward the most suitable option for your dental restoration. By making an informed decision and considering the various techniques available, you can achieve not only a beautiful smile but also a long-lasting and functional dental crown. Remember, regular dental check-ups and good oral hygiene practices are key to maintaining the health and longevity of your dental crowns.
