Dental health is not just about maintaining a beautiful smile; it’s about ensuring the strength and functionality of your teeth. One of the popular solutions for restoring damaged or decayed teeth is the porcelain fused to metal (PFM) dental crown. This type of crown offers a blend of aesthetic appeal and structural support, making it a preferred choice among dental professionals and patients alike.

Porcelain Fused to Metal Dental Crown Explained

A porcelain fused to metal dental crown restores and protects a tooth weakened by decay, damage, or extensive dental work. It consists of two main components: a metal base and a porcelain exterior. The metal base provides the crown with the necessary strength and durability, while the porcelain overlay offers a natural, tooth-like appearance.

The process of getting a PFM crown typically involves two visits to the dentist. During the first visit, the dentist will prepare the affected tooth by removing any decay and shaping it to fit the crown. Impressions of the tooth are then taken and sent to a dental laboratory, where the crown is custom-made. On the second visit, the dentist will fit the crown, make any necessary adjustments, and cement it in place.

The Pros and Cons of a Porcelain Fused to Metal Crown

Like any dental restoration, PFM crowns come with their own set of advantages and disadvantages. Understanding these can help patients make informed decisions about their dental care.

Pros:

Durability and Strength: The metal core of a PFM crown provides a strong foundation that can withstand the forces of chewing and biting, making it suitable for both front and back teeth.
Aesthetic Appeal: The porcelain overlay can be color-matched to the surrounding teeth, offering a natural and seamless appearance.
Versatility: PFM crowns can be used in a variety of dental situations, from restoring single teeth to supporting dental bridges.

Cons:

Metal Exposure: Over time, the metal base may become visible at the gum line, especially if the gums recede, which can affect the crown’s aesthetic appeal.
Wear on Opposing Teeth: The porcelain surface can be abrasive and may cause wear on the opposing natural teeth.
Potential for Chipping: While the porcelain exterior is designed to mimic natural tooth enamel, it is more susceptible to chipping and cracking compared to all-metal crowns.

When a Porcelain Fused to Metal Crown is Recommended

Dentists may recommend a PFM crown in several scenarios, each aimed at preserving the functionality and appearance of the patient’s teeth. Here are some common situations where a PFM crown might be the preferred choice:

Large Fillings or Decay: When a tooth has been extensively damaged by decay or has a large filling that compromises its structural integrity, a PFM crown can provide the necessary support.
Root Canal Treatment: Teeth that have undergone root canal therapy are often weakened and more prone to fracture. A PFM crown can protect these teeth and restore their functionality.
Cracked or Broken Teeth: For teeth that are cracked or broken but still retain enough healthy structure, a PFM crown can hold the tooth together and prevent further damage.
4. Dental Bridges: PFM crowns are commonly used to anchor dental bridges, providing support to the prosthetic teeth and maintaining the alignment of the patient’s bite.
5. Cosmetic Improvements: In some cases, PFM crowns can be used to improve the appearance of misshapen or discolored teeth, enhancing the overall smile.

Other Types of Dental Crown Material Options to Consider

While PFM crowns are a popular choice, there are several other materials available for dental crowns, each with its own unique benefits and drawbacks. Here are some of the most common alternatives:

1. All-Ceramic or All-Porcelain Crowns

Pros: These crowns offer the best natural color match and are highly aesthetic. They are an excellent choice for front teeth and for patients with metal allergies.
Cons: They are less durable than metal-based crowns and may not be suitable for back teeth where chewing forces are greater.

2. Gold Crowns

Pros: Gold crowns are extremely durable and biocompatible. They cause minimal wear to opposing teeth and have a long history of success in dental restorations.
Cons: The metallic color is not aesthetically pleasing for most people, making them less popular for visible teeth.

3. Zirconia Crowns

Pros: Zirconia crowns are both strong and aesthetically pleasing. They offer high durability and can withstand significant chewing forces. They are also biocompatible and less likely to cause allergic reactions.
Cons: Even though dentists can match zirconia’s color to your teeth, its opacity can sometimes make it appear less natural than all-porcelain crowns.

4. Composite Resin Crowns

Pros: Composite resin crowns cost less and can match the color of natural teeth. They are easier to repair if damaged.
Cons: They are less durable and more prone to wear and staining over time compared to other materials.

Are Porcelain Fused to Metal Crowns Good?

Porcelain fused to metal crowns reliably address and effectively solve many dental restoration needs. They strike a balance between durability and aesthetics, making them suitable for a wide range of applications. Several factors make porcelain fused to metal crowns a popular choice for dental restorations:

Strength and Longevity: The metal core of a PFM crown provides robust support, making it a durable option that can last many years with proper care.
Natural Appearance: The dentist customizes the porcelain overlay to perfectly match the color and shape of your natural teeth, creating a pleasing and realistic look.
Cost-Effective: Compared to all-ceramic crowns, PFM crowns tend to be more affordable while still offering excellent performance and aesthetics.

How Long Does a Porcelain Fused to Metal Crown Last?

The lifespan of a PFM crown can vary based on several factors, including oral hygiene, dietary habits, and the crown’s location in the mouth. On average, PFM crowns can last between 5 to 15 years. However, with good oral care and regular dental check-ups, some PFM crowns can last even longer.

Factors Influencing Longevity:

Oral Hygiene: Regular brushing, flossing, and dental cleanings are essential to maintaining the health of the crowned tooth and surrounding gums.
Diet: Avoiding hard and sticky foods can prevent damage to the crown and extend its lifespan.
Bruxism: Teeth grinding can put extra stress on the crown, leading to premature wear. Wearing a night guard can help mitigate this issue.

How Much Does a Porcelain Fused to Noble Metal Crown Cost?

The cost of a PFM crown can vary widely depending on several factors, including the dental practice’s location, the complexity of the procedure, and the materials used. On average, the cost of a PFM crown ranges from $800 to $1,500 per tooth. Dental insurance can offset the cost of a porcelain fused to metal crown, especially if it’s medically necessary.
