Many people have a concern — if they have a dental crown, bridge, or implant, can they undergo an MRI or CT scan?
There is also a fear that such scans may not be possible in the future. Let’s clear these misconceptions.
Common Concerns:
First, there is a fear that due to the strong magnetic field of MRI, the crown or implant might be pulled out.
Second, there is a concern that the energy in MRI may heat the metal and cause burns inside the mouth.
Third, there is a doubt whether the image quality of the scan will be affected.
Understanding the Materials:
Most dental metals are safe.
Cobalt-chromium alloys → Have very minimal magnetic properties.
Titanium → Non-magnetic, so there is no reaction in MRI.
Acrylic dentures → Being plastic, they do not cause any issues.
However, removable appliances (removable dental devices) should be removed before the scan.
Modern MRI Techniques:
In modern MRI machines, small distortions in images can be corrected using software. Therefore, image quality is usually not a problem.
Practical Advice:
If the crown or bridge is loose, consult a dentist before the scan.
If necessary, it can be properly fitted or temporarily removed.
Summary:
Even if you have dental implants, crowns, or bridges, MRI/CT scans can be done safely — there is no need to worry 👍
