Can You Get an MRI if You Have Dental Crowns?

Can You Get an MRI if You Have Dental Crowns?
June 1, 2023

Many people with dental crowns always ask if MRI can be done with dental crowns. If you have dental crowns, you can usually get an MRI. Most dental crowns in Paso Robles are made of non-magnetic materials such as porcelain, ceramic, or zirconia, which are unaffected by an MRI machine’s magnetic field. As a result, having dental crowns should not interfere with the MRI scan results or cause any harm to the patient.

On the other hand, metal crowns with metal components may cause artifacts or distortions in the images produced by the MRI scan in some cases. This is because magnetic fields can affect metal objects, causing signal loss or distortion in the surrounding tissues.

Factors That Determine Whether You Can Get an MRI with Dental Crowns

Here are five factors that may influence whether you can get an MRI while wearing dental crowns:

  1. The type of crown you have can affect your ability to have an MRI. Most non-metallic crowns, such as those made of porcelain, ceramic, or zirconia, are MRI-safe. On the other hand, metal crowns or those containing metal components may not be safe.
  2. Age of the Crown: The age of your crown may impact its ability to withstand an MRI. Older crowns may have deteriorated or been damaged over time, making them more vulnerable to magnetic fields.
  3. Crown size and location: The size and location of your crown can also impact your ability to undergo an MRI. Here are five factors that may influence whether you can get an MRI while wearing dental crowns:
  4. The magnetic field strength of the MRI machine can also affect your ability to have an MRI with dental crowns. Higher-powered machines may introduce more distortion or artifacts into the images.
  5. Personal health considerations: Your overall health and medical history may also influence your ability to undergo an MRI with dental crowns. Your healthcare provider may need to evaluate your risk factors and decide on the best course of action for you.

Alternatives to MRI for Patients with Dental Crowns

Patients with dental crowns who cannot have an MRI have other diagnostic imaging options. Here are a few examples:

  • A computed tomography (CT) scan

This is a non-invasive diagnostic imaging test that produces detailed body images. It creates cross-sectional images of the area being scanned using X-rays. Because CT scans do not use magnetic fields, so they are generally safe for dental crown patients.

  • Ultrasound imaging

Ultrasound imaging creates images of the body by using high-frequency sound waves. Because it does not use magnetic fields or ionizing radiation, it is a non-invasive and safe imaging option for patients with dental crowns.

  • PET scan

A positron emission tomography (PET) scan is a type of diagnostic imaging test that creates images of the body using a radioactive tracer. Because PET scans do not use magnetic fields, so they are generally safe for dental crown patients.

  • Bone Scan

This diagnostic imaging test creates images of the bones using a small amount of radioactive material. Because it does not use magnetic fields, it is a non-invasive and safe imaging option for patients with dental crowns.

Consulting with Your Dentist and Doctor

If you have dental crowns and require an MRI, you must consult with both your dentist near you and your doctor. Here are some topics to bring up with them:

  • Type of crown: Inform your dentist and doctor at Vineyard Dental & Orthodontics about the type of crown you have. They can tell if it contains any metal or if it is made of non-magnetic materials suitable for an MRI.
  • Crown age and condition: The age and condition of your crown can also impact its ability to withstand an MRI. Your dentist can inspect the crown and advise you on any precautions you should take.
  • The magnetic field strength of the MRI machine can also affect your ability to have an MRI with dental crowns. Your doctor can advise you on the appropriate MRI machine strength to use.
  • Personal health considerations: Your overall health and medical history may also influence your ability to undergo an MRI with dental crowns.
