Can You Have An MRI With Dental Crowns?

Posted .

You can indeed have an MRI with dental crowns. Dental crowns, usually made from non-magnetic materials like porcelain or ceramic, do not interfere with the MRI’s magnetic field. It’s crucial to inform the MRI technician about your dental crowns to ensure proper precautions for accurate imaging results. Dental crowns, also known as caps, are custom-made covers for damaged teeth. By understanding this, you can confidently undergo MRI procedures, knowing your dental crowns won’t hinder your medical imaging needs.

Note: Always consult with your dentist and healthcare provider for personalized advice.

The Importance of Dental Crowns

  • Dental crowns protect and strengthen damaged teeth.
  • Recommended for teeth with root canal therapy, large fillings, or severe decay.
  • Restore function and appearance, allowing patients to eat, speak, and smile confidently.
  • Designed to be durable and long-lasting, preserving natural tooth structure.

Understanding MRI Scans

  • MRI (Magnetic Resonance Imaging) is a non-invasive diagnostic procedure.
  • Utilizes powerful magnets and radio waves for detailed internal body structure images.
  • Commonly used for diagnosing injuries, tumors, and diseases.
  • Provides valuable data for accurate diagnoses and treatment planning.

The Concerns with and MRI with Dental Crowns

  • Some dental crowns contain non-magnetic materials like porcelain or ceramic.
  • However, certain crowns may have metal components, potentially affecting MRI scans.
  • Metal substructures or alloys can interfere with MRI, leading to image artifacts.

Types Dental Crowns for MRI Compatibility

The compatibility of dental crowns with MRI scans depends on the type of crown material used. Here are the most common types of dental crowns and their MRI compatibility:

1. All-Ceramic Crowns

All-ceramic crowns, such as porcelain or zirconia crowns, do not contain any metal and are considered MRI-safe. They are highly compatible with MRI scans, as they do not produce any artifacts that can interfere with the image quality.

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

PFM crowns have a metal substructure covered with a layer of porcelain. The metal substructure can be made of non-magnetic metals, such as gold or titanium, or magnetic metals, such as stainless steel or cobalt-chromium alloys. Non-magnetic PFM crowns are generally considered MRI-safe, while magnetic PFM crowns may cause artifacts on the MRI images.

3. Metal Crowns

Metal crowns, such as gold or stainless steel crowns, are MRI-safe as long as they do not contain any magnetic components. However, metal crowns can still produce artifacts on the MRI images, which may affect the interpretation of the results.

Precautions and Recommendations for MRI with Dental Crowns

  • It’s crucial to notify your healthcare provider about your dental crowns before undergoing an MRI to assess their compatibility with the scan.
  • Your healthcare provider will determine the type of crowns you have and the best course of action. In some cases, temporary crown removal might be necessary to ensure precise imaging.
  • Collaboration between your dentist and healthcare provider is essential to ensure your safety and provide the best care during the MRI procedure.

Benefits of Dental Crowns

  • Dental crowns bring multiple advantages to patients. They can enhance the appearance and functionality of damaged teeth.
  • By restoring the aesthetics of your smile and safeguarding the underlying tooth structure, they help boost confidence.
  • Dental crowns are known for their durability and long-lasting properties, offering a reliable solution to various dental issues.


In conclusion, the compatibility of dental crowns with MRI scans depends on the type of crown material used. All-ceramic crowns are generally considered MRI-safe, while PFM crowns and metal crowns may cause artifacts on the MRI images. It is important to inform your healthcare provider about your dental restorations before undergoing an MRI scan to ensure accurate imaging. Dental crowns offer significant benefits for patients and can greatly improve the function and appearance of damaged teeth.

Key Takeaways: Can You Have an MRI With Dental Crowns?

  • Yes, you can have an MRI with dental crowns.
  • Dental crowns are usually made of non-magnetic materials, such as porcelain or ceramic, which are safe for MRI scans.
  • However, it’s important to inform the medical staff about your dental crowns before the MRI to ensure safety and accurate results.
  • In some cases, the metal used in dental crowns may cause artefacts on the MRI images, but it usually doesn’t interfere with the scan itself.
  • If you have any concerns or doubts, consult with your dentist or the medical staff performing the MRI to address any specific issues related to your dental crowns.

Frequently Asked Questions

Are dental crowns safe for MRI scans?

Dental crowns are generally safe for MRI scans if made of inert ceramic material. However, it’s crucial to inform the radiologist or technician about the metal dental crowns before the scan to warn them about the chances of potential artifacts or distortions in the images. In cases where there are concerns about crowns interfering with the MRI, an alternative imaging technique like a CT scan may be recommended. Consulting with your healthcare provider and the imaging center is advisable to ensure the safety and accuracy of the MRI scan.

Can dental crowns cause discomfort during an MRI?

Dental crowns do not cause discomfort during an MRI; however, anxiety or claustrophobia can be triggered by the MRI machine. Discuss any concerns with your healthcare provider before the scan, as accommodations like sedatives or open MRI machines may be available to ensure a comfortable experience. Communication is key for a positive MRI experience.

Are there any risks associated with dental crowns and MRI scans?

The risks of dental crowns in MRI scans are generally minimal. However, loose or damaged crowns may pose dislodgment risks. Regular dental check-ups are vital to ensuring crown stability. Crowns with ferromagnetic materials can heat or displace due to MRI magnets, making it essential to inform the radiologist or technician about crown composition before the scan.

Do all MRI centers allow patients with dental crowns?

Patients with dental crowns can typically have MRI scans, but it’s crucial to inform the imaging centre beforehand for a thorough assessment. Consulting with your healthcare provider or dentist is wise to ensure a safe and suitable MRI experience with dental crowns, considering your specific needs and any potential concerns.

Can dental crowns affect the accuracy of MRI images?

Dental crowns, particularly those with metal components, can cause distortions in MRI images, potentially impacting accuracy. However, modern MRI technology and skilled radiologists can reduce these distortions through parameter adjustments and specific sequences. Providing detailed crown information to the imaging center is crucial for accurate diagnosis. Advances in techniques and radiologist expertise have improved MRI’s compatibility with dental crowns, ensuring better image quality.

Final Thought: Can You Have an MRI With Dental Crowns?

Having dental crowns should not prevent you from having an MRI. Most crowns are made from non-magnetic materials, reducing the risk of interference with the MRI’s magnetic field. Informing your healthcare provider and MRI technician about your crowns is essential for a safe and accurate scan. Advancements in MRI technology have led to protocols and techniques that minimize artifacts from dental restorations, even if they contain metal. Adjusting the MRI machine settings can accommodate metal-containing crowns for accurate scans. Consult with your dentist and healthcare provider to determine the best approach, ensuring both dental health and overall well-being. Modern materials and technology enable safe MRIs with dental crowns.
