Can MRI be done with dental crowns? This is a common question many people ask before undergoing an MRI scan. Since an MRI (Magnetic Resonance Imaging) uses strong magnetic fields and radio waves to create detailed body images, patients often worry that metal-based dental restorations might interfere with the process. The good news is that in most cases, having dental crowns does not prevent you from getting an MRI safely.
However, understanding how crowns interact with MRI technology can ease your concerns and help you prepare for your medical imaging procedure. Let’s explore everything you need to know in simple terms.
What Happens During an MRI Scan?
An MRI machine uses powerful magnets and radio waves to capture detailed images of your internal organs and tissues. Unlike X-rays or CT scans, it doesn’t use radiation.
During the scan:
-
You’ll lie still on a sliding bed that moves into the MRI machine.
-
The machine creates a magnetic field that aligns the atoms in your body.
-
A computer then translates these signals into highly detailed images.
Because of the strong magnet, anything metallic inside your body can potentially react and distort the images. That’s why patients are usually asked to remove jewelry, piercings, or metal accessories before the scan.
Are Dental Crowns Safe for MRI?
In most cases, dental crowns are completely safe during an MRI. Most modern crowns are made of non-magnetic materials such as:
-
Porcelain
-
Ceramic
-
Composite resin
-
Zirconia
Even crowns that contain a small amount of metal are usually made with non-ferromagnetic alloys like gold or titanium. These materials are non-reactive to magnetic fields, meaning they won’t move or heat up inside the MRI scanner.
So, if you’re wondering, “Can MRI be done with dental crowns?” — the answer is yes, it’s safe in the vast majority of cases.
When to Inform Your Radiologist About Dental Crowns
Even though most dental restorations are MRI-compatible, it’s always wise to inform your doctor or MRI technician about them. Transparency helps ensure your safety and the quality of your imaging results.
Here’s what you should share before the scan:
-
The type of dental crown you have (metal, ceramic, or porcelain).
-
The number and location of your crowns.
-
Any dental implants, bridges, or braces currently in your mouth.

Can Dental Crowns Affect MRI Image Quality?
In rare cases, metal crowns can cause minor image distortions known as “artifacts.” These appear as blurry or shadowy areas on the MRI image. However, this effect is usually limited to the mouth or head region and does not affect scans of other parts of the body, such as your back or abdomen.
If your scan involves your jaw, neck, or head area, your radiologist may take steps to reduce these effects, such as:
-
Adjusting the scanning angle or sequence
-
Using advanced software filters to correct distortion
-
Focus on areas away from the crown
In most instances, these minor issues do not interfere with diagnosis or treatment.
What If You Have Metal-Based Dental Crowns?
If your crowns are older or contain magnetic metals like nickel, you might feel a slight tug during the MRI. This sensation is rare, but it’s still important to notify your radiologist before the procedure.
You don’t need to worry about damage — modern MRI technology is designed to handle such situations safely. However, medical professionals may recommend:
-
Conducting a safety check on your dental work
-
Adjusting the MRI settings for comfort and accuracy
Remember, it’s best to share every detail about your dental history before your scan.
What to Do Before Your MRI Appointment
To make your MRI experience smooth and worry-free, follow these simple steps:
-
Inform your doctor about all dental work, including crowns, bridges, or implants.
-
Carry dental records if available — they can help identify the materials used.
-
Remove all removable dental appliances, such as retainers or dentures, before the scan.
-
Stay relaxed. MRI scans are painless, and your technician will guide you throughout the process.
Knowing that your dental crowns are safe gives you peace of mind during the procedure.
