Are Dental Crowns Toxic?

Posted .

Concerns about the potential toxicity of dental crowns have been raised due to the materials used in these dental restorations. Dental crowns are typically crafted from materials like porcelain, ceramic, or metal alloys, and their safety for use in the mouth is of utmost importance.

The good news is that dental crowns, in general, are not toxic. These materials undergo rigorous testing to ensure they are biocompatible and safe for oral use. However, individuals with allergies or sensitivities to specific crown materials should discuss their concerns with a dentist before undergoing crown placement.

Are Dental Crowns Toxic?

Dental crowns are a common dental treatment used to restore damaged teeth and improve their appearance. However, there has been some concern about the potential toxicity of dental crowns. In this article, we will explore whether dental crowns are toxic and discuss the risks and benefits associated with them.

What are Dental Crowns?

Dental crowns are tooth-shaped caps that are placed over damaged or decayed teeth to restore their shape, size, strength, and improve their appearance. They are typically made from various materials, including porcelain, metal alloys, or a combination of both. Dental crowns can be used to cover teeth that have undergone root canal treatment, have large fillings, or are severely damaged.

The Materials Used in Dental Crowns

Dental crowns can be made from different materials, each with its own set of advantages and disadvantages. The most common materials used for dental crowns include:

1. Porcelain: Porcelain crowns are known for their natural appearance and are often used for front teeth. They can be color-matched to the surrounding teeth, creating a seamless and aesthetically pleasing result.

2. Metal Alloys: Metal crowns, such as those made from gold or silver alloys, are strong and durable. They are often used for molars or teeth that require additional strength due to excessive biting forces.

3. Porcelain-Fused-to-Metal (PFM): PFM crowns combine the strength of metal with the natural appearance of porcelain. They have a metal core covered with a layer of porcelain, providing both strength and aesthetics.

Are Dental Crowns Toxic?

There is ongoing debate about the potential toxicity of dental crowns, particularly those that contain metal alloys. Some concerns have been raised about the release of metal ions from dental crowns into the oral cavity, which could potentially have adverse health effects.

However, it is important to note that the materials used in dental crowns are generally considered safe and have a long history of use in dentistry. Dental professionals carefully select materials that are biocompatible and minimize the risk of toxicity. Additionally, the amount of metal ions released from dental crowns is typically minimal and unlikely to cause harm, especially when compared to other potential sources of metal exposure in our daily lives.

Risks and Benefits of Dental Crowns

Like any dental treatment, there are both risks and benefits associated with dental crowns. It is essential to weigh these factors when considering whether dental crowns are the right option for you.


1. Allergic Reactions: In rare cases, individuals may have an allergic reaction to the materials used in dental crowns, particularly metal alloys. It is important to inform your dentist of any known allergies before undergoing treatment.

2. Sensitivity: Some individuals may experience temporary sensitivity to hot or cold temperatures after receiving a dental crown. This sensitivity typically subsides within a few weeks.


1. Restored Function: Dental crowns can improve the functionality of damaged teeth, allowing you to chew and speak properly.

2. Aesthetics: Crowns made from porcelain or porcelain-fused-to-metal can provide a natural and aesthetically pleasing appearance, enhancing your smile.

3. Durability: Dental crowns are known for their durability and can withstand the forces of biting and chewing.

4. Protection: Dental crowns can protect weak or damaged teeth from further decay or damage.

In conclusion, while there may be some concerns about the potential toxicity of dental crowns, the materials used in their construction are generally considered safe and biocompatible. Dental professionals carefully select materials to minimize the risk of toxicity and ensure patient safety. As with any dental treatment, it is essential to discuss any concerns or questions with your dentist to make an informed decision about your oral health.

Frequently Asked Questions

Are Dental Crowns Toxic?

When it comes to dental crowns, concerns about their toxicity are understandable. However, modern dental crowns are generally safe and non-toxic. The materials used in dental crowns have been extensively tested and approved by regulatory bodies. They are designed to be biocompatible and do not pose a significant risk to your health.

Most dental crowns are made from porcelain, ceramic, or a combination of metal and porcelain. These materials are chosen for their durability, aesthetics, and compatibility with the human body. While some metals used in crowns, such as nickel, can cause allergic reactions in a small percentage of people, your dentist will take into account any known allergies or sensitivities before recommending a specific material for your crown.

How are Dental Crowns Made?

Dental crowns are custom-made to fit your individual tooth and mouth. The process usually involves multiple steps. Firstly, your dentist will take impressions of your teeth to create an accurate model. This model is then sent to a dental laboratory, where skilled technicians will craft your crown.

The dental laboratory will use the impressions and any other specific instructions from your dentist to create a crown that matches the shape, size, and color of your natural teeth. The materials used for the crown, such as porcelain or ceramic, are carefully selected to ensure a durable and aesthetically pleasing result. Once the crown is ready, your dentist will bond it to your tooth, giving you a restored and functional smile.

How Long Do Dental Crowns Last?

The lifespan of a dental crown can vary depending on various factors, including the material used and how well you take care of your oral health. On average, dental crowns can last between 10 to 15 years. However, with proper maintenance and regular dental check-ups, they can last even longer.

To ensure the longevity of your dental crown, it is important to practice good oral hygiene. Brushing twice a day, flossing daily, and using an antimicrobial mouthwash can help prevent decay and gum disease, which can compromise the integrity of the crown. Additionally, avoiding habits such as grinding or clenching your teeth can also extend the lifespan of your crown.

Can Dental Crowns Cause Allergic Reactions?

While dental crowns are generally safe and well-tolerated, some individuals may have allergic reactions to certain materials used in crowns. Nickel, a metal commonly used in dental alloys, can cause allergic responses in some people. If you have a known allergy to nickel or other metals, it is important to inform your dentist before getting a dental crown.

Your dentist will consider your allergies and sensitivities when selecting the appropriate material for your crown. Alternative materials such as all-ceramic or zirconia crowns can be used for individuals with metal allergies. By discussing your concerns and medical history with your dentist, they can ensure the crown material chosen is compatible with your body.

Are Dental Crowns a Safe Option for Restoring Teeth?

Dental crowns are a widely accepted and safe option for restoring teeth. They have been used in dentistry for many years with proven success. The materials used in dental crowns, such as porcelain and ceramic, are biocompatible and well-tolerated by the body.

By placing a dental crown, your dentist can protect and strengthen a weakened or damaged tooth, restoring its functionality and appearance. Dental crowns can also be used to improve the aesthetics of your smile by covering discolored or misshapen teeth. Overall, dental crowns are a reliable and safe treatment option for various dental concerns.
