Do Dental Crowns Have Metal In Them?

Posted .

When it comes to dental crowns, patients often wonder if they contain metal. The answer varies: while traditional crowns may include metal alloys like gold or silver for strength, newer options like porcelain or zirconia offer metal-free alternatives, providing a more natural appearance. Dentists consider individual needs and preferences when recommending the best type of crown. Whether metal-based or metal-free, both options ensure durable and aesthetically pleasing dental restorations, contributing to a confident smile and optimal oral health.

Do Dental Crowns Have Metal in Them?

Dental crowns are a common dental treatment used to restore damaged or decayed teeth. They are designed to cover the entire tooth, providing protection and improving its appearance. One question that often arises when considering dental crowns is whether or not they contain metal. In this article, we will explore the different types of dental crowns and discuss whether or not they have metal in them.

Types of Dental Crowns

There are several types of dental crowns available, each with its own unique characteristics. The most common types of dental crowns include porcelain-fused-to-metal (PFM) crowns, all-ceramic crowns, and metal crowns.

1.PFM crowns are made by combining a metal substructure with a layer of porcelain. This combination allows for strength and durability while also providing a natural-looking appearance. The metal substructure is typically made of a non-precious metal alloy, such as nickel-chromium or cobalt-chromium.

2. All-ceramic crowns, on the other hand, are made entirely of ceramic material. They are highly aesthetic and can closely mimic the natural color and translucency of the surrounding teeth. These crowns are a popular choice for patients who prefer a metal-free option.

3. Metal crowns, also known as gold crowns, are made entirely of a metal alloy, such as gold or a gold alloy. These crowns are extremely durable and long-lasting, but their metallic appearance may not be desired by all patients.

Do PFM Crowns Have Metal in Them?

PFM crowns, as the name suggests, do have metal in them. The metal substructure provides the strength and stability needed to withstand the forces of chewing and biting. However, the metal is not visible when the crown is in place, as it is covered by a layer of porcelain. This allows for a natural-looking result.

Are All-Ceramic Crowns Metal-Free?

Yes, all-ceramic crowns are metal-free. They are made entirely of ceramic material, such as porcelain or zirconia. This makes them an excellent choice for patients who have metal allergies or sensitivities. All-ceramic crowns are also highly aesthetic and can blend seamlessly with the surrounding teeth.

Benefits of Metal-Free Crowns

There are several benefits to choosing metal-free dental crowns.

  • One of the main advantages is their natural appearance. All-ceramic crowns can closely mimic the color, shape, and translucency of natural teeth, resulting in a seamless smile.
  • Another benefit is the absence of metal allergies or sensitivities. Some individuals may have adverse reactions to metal, such as gum irritation or discoloration. Metal-free crowns eliminate this concern, making them a safe and comfortable option for those with sensitivities.
  • Furthermore, metal-free crowns are highly biocompatible. They do not interfere with the body’s natural tissues or cause any adverse reactions. This makes them a suitable choice for individuals with underlying health conditions or compromised immune systems.


In conclusion, dental crowns can contain metal or be metal-free, depending on the type of crown chosen. PFM crowns have a metal substructure covered by porcelain, while all-ceramic crowns are entirely metal-free. Both options have their own advantages and considerations, so it is essential to consult with a dental professional to determine the best choice for your specific needs. Metal-free crowns offer a natural appearance, are free of metal allergies, and are highly biocompatible, making them a popular choice for many patients.

Frequently Asked Questions

What materials are used in dental crowns?

When it comes to dental crowns, there are several materials that can be used. Traditional crowns often include a metal base, such as gold or silver, which provides strength and durability. However, metal crowns are not as aesthetically pleasing as other options. For those looking for a more natural appearance, porcelain-fused-to-metal crowns are commonly used. These crowns have a metal base for strength, but the visible portion is covered with porcelain, which can be color-matched to the surrounding teeth.

There are also all-porcelain or all-ceramic crowns, which offer the most natural-looking results. These crowns are made entirely of porcelain or ceramic material, providing excellent aesthetics. While they may not be as strong as metal crowns, they are still durable and can be a suitable option for many patients.

Do dental crowns contain any metal?

Yes, dental crowns can contain metal components. Traditional crowns often have a metal base, which provides strength and stability. However, the metal is typically not visible once the crown is placed, as it is covered with a layer of porcelain or ceramic to match the natural teeth. So, while there may be metal in the structure of the crown, it is not visible and does not affect the overall appearance.

It’s important to note that there are also metal-free options available, such as all-porcelain or all-ceramic crowns, which do not contain any metal. These crowns are becoming increasingly popular due to their natural appearance and biocompatibility.

Are there any concerns with metal-containing dental crowns?

While metal-containing dental crowns have been used for many years and are considered safe, some individuals may have concerns about potential allergies or sensitivity to the metal. It’s important to discuss any allergies or sensitivities with your dentist before getting a dental crown. In some cases, alternative materials can be used to avoid any potential issues.

If you have a known metal allergy or sensitivity, it’s best to opt for metal-free crowns, such as all-porcelain or all-ceramic crowns. These crowns provide excellent aesthetics and eliminate the risk of metal-related allergies or sensitivities.

How long do metal-containing dental crowns last?

Metal-containing dental crowns are known for their durability and longevity. With proper care and maintenance, these crowns can last for many years, often up to 15 years or more. However, the lifespan of a dental crown can vary depending on factors such as oral hygiene practices, dental habits, and overall oral health.

Regular dental check-ups and cleanings are essential to ensure the longevity of your dental crown. Your dentist can assess the condition of the crown and make any necessary adjustments or repairs to prolong its lifespan.

Can metal-free dental crowns be used for any tooth?

Metal-free dental crowns, such as all-porcelain or all-ceramic crowns, can be used for most teeth. They are particularly suitable for front teeth, as they provide excellent aesthetics and can be color-matched to blend seamlessly with the natural teeth. However, for back teeth that require more strength and durability, metal-containing crowns may be recommended.

Your dentist will assess your specific dental needs and discuss the best options for your individual case. They will take into consideration factors such as the location of the tooth, your bite force, and your aesthetic preferences to determine the most appropriate type of dental crown for you.
