Can MRI Be Done with Dental Crowns? A Patient Guide
Many patients ask: Can MRI be done with dental crowns? The short answer is yes, in most cases. The specific crown material affects safety and image quality. This guide explains what to expect and how to prepare.
Can mri be done with dental crowns
An MRI machine uses powerful magnets and radiofrequency pulses to create detailed images of soft tissues. Because the magnetic field interacts with metal, dental crowns require evaluation. Crown materials fall into three primary categories regarding MRI compatibility.
Non-Metal and Ceramic Crowns (Fully Compatible)
If your crown is made entirely of porcelain, ceramic, or composite resin, it is non-magnetic and safe. Materials like zirconium oxide (zirconia) cause no interference or image distortion. They do not react to the magnetic field. Read about crowns and bridges to learn more about these treatments.
Precious Metals and Amalgams (Safe but Minor Artifacts)
Crowns made of gold, silver, or platinum alloys are not strongly attracted to magnets. They pose no physical hazard. However, these metals can conduct electricity and create tiny eddy currents. This may cause minor image distortions (artifacts) around the mouth area.
Ferromagnetic Base Metals (Risk of Distortions and Displacement)
Older or lower-cost crowns may use base metal frameworks containing cobalt-chromium, nickel, or stainless steel. These materials are ferromagnetic and react strongly to magnets. They rarely become projectiles because they are cemented to the tooth. But the magnetic pull can stress the dental cement. They also create significant "black hole" artifacts on scans, which may obscure surrounding anatomy. Read about crowns and cancer risk to understand more about dental crown materials.
Other Dental Restorations and MRI Safety
Beyond crowns, patients may have implants, fillings, bridges, or orthodontic appliances. Most modern dental implants use titanium, which is generally MRI-safe. However, implants can cause some image distortion. Amalgam fillings are non-magnetic and safe, though they may cause minor artifacts. Composite resin fillings are completely safe and produce no artifacts. Orthodontic braces with metal brackets can cause significant artifacts. Always inform your MRI technologist about all dental restorations you have.
How Dental Crowns Affect MRI Image Quality
Metal crowns can create artifacts—distortions or signal loss—in MRI images. These artifacts can obscure nearby structures. For example, a metal crown on a molar can cause a signal void, potentially hiding a tumor or infection in the jawbone. Artifacts can also distort images of the brain, especially the temporal lobes. This can lead to false positives or missed small lesions. Radiologists may adjust imaging protocols to reduce these effects.
Potential Complications During a Scan
When determining if an MRI can be done with dental crowns, radiologists look for three technical issues:
Artifact Formation: Differences in magnetic susceptibility between tissue and metal cause local field distortions. This reduces image quality.
Radiofrequency Heating: Rapid MRI pulses can cause minor thermal heating in metal components. This is usually safe but may cause slight discomfort.
Mechanical Displacement: In rare cases with poor dental cement or structural integrity, a ferromagnetic framework may feel a tug from the scanner.
Alternatives to MRI for Patients with Dental Crowns
If an MRI is not recommended due to crown type or other reasons, healthcare providers may consider alternatives. Computed tomography (CT) scans offer detailed cross-sectional images of bones and blood vessels. CT is useful for dental structures and the temporomandibular joint. However, CT uses ionizing radiation. Cone-beam CT (CBCT) provides high-resolution 3D images of dental and facial structures with lower radiation. Ultrasound is radiation-free and can assess soft tissues. Your dentist and physician will choose the safest option for your situation.
Estimated Treatment Costs at Vitrin Clinic
For patients who want to replace older metallic restorations with MRI-friendly zirconia or ceramic crowns, dental tourism is popular. Vitrin Clinic in Istanbul, Turkey, offers advanced cosmetic and restorative procedures at lower costs than Western countries. The average cost of a premium zirconia or E-max ceramic crown at Vitrin Clinic ranges between $200 and $330 per tooth. This is more affordable than in the US or UK, where a non-metal crown can exceed $1,000 to $1,500. Read about gold crown value to learn more.
Best Practices Before Your MRI Appointment
If you have dental crowns and need an MRI, follow these steps:
Inform the Technologist: Tell the MRI technician about your dental crowns before entering the scanner room.
Know Your Materials: Contact your dentist to verify whether your crowns contain base metals or are ceramic/noble gold.
Check for Loosening: Ensure your crowns feel secure. If the scan targets your brain or neck, the radiologist may adjust sequences to minimize artifacts.
List All Restorations: Mention any implants, fillings, braces, or bridges along with crowns.

Frequently Asked Questions About MRI and Dental Crowns
Q: Can I have an MRI if I have a dental crown?
A: Yes, in most cases. Non-metal crowns are safe and cause minimal artifacts. Metal crowns are safe but may cause artifacts. Always inform your radiologist.
Q: Will my dental crown heat up during an MRI?
A: No, dental crowns do not contain ferromagnetic materials that would heat up or move. The risk of heating is minimal. Still, tell the technologist about any metal in your mouth.
Q: Can I get an MRI if I have a dental implant?
A: Yes, most implants are titanium and MRI-safe. They may cause some image distortion, which the radiologist can account for.
Q: What should I tell my doctor before an MRI?
A: Provide a complete list of dental restorations, including crowns, bridges, implants, fillings, and braces. This helps the radiology team plan properly.
Q: Are there alternatives to MRI if I have concerns?
A: Yes, CT, CBCT, and ultrasound are alternatives. Each has advantages and limitations. Your provider will recommend the best option for your needs.
In summary, yes, an MRI can be done with dental crowns, but communication with your healthcare team is essential.
