Your bridge won’t normally get pulled out of your mouth during an MRI. That’s the scary image people sometimes have in their heads, but it isn’t how a fixed dental bridge works. A bridge is cemented onto supporting teeth or attached as part of a dental restoration, so it stays where it belongs.<\/p>\r\n
Some bridges contain metal. But most dental metals used in fixed restorations don’t pose a major safety problem during an MRI. The bigger issue is that metal can sometimes interfere with the images, especially when the scan is focused around your head or face.<\/p>\r\n
\u2022 Porcelain or ceramic bridges usually cause little concern because they contain little or no metal.<\/p>\r\n
\u2022 Metal-containing bridges are often still compatible with MRI, though the exact alloy matters.<\/p>\r\n
\u2022 Older dental work can be harder to identify, especially if you don’t have the original treatment records.<\/p>\r\n
This is where things get a little more interesting. A dental bridge can create an area of distortion called an artifact. It basically means the metal interferes with the MRI signal and leaves some distortion around the restoration.<\/p>\r\n
That usually matters most when the radiologist needs a very clear picture of the mouth, jaw, face, or nearby tissues. If you’re having an MRI of your knee, for example, your dental bridge isn’t sitting anywhere near the area being examined, so the effect on the scan is usually irrelevant.<\/p>\r\n
\u2022 If you know the bridge contains metal, say so before the scan rather than keeping quiet about it.<\/p>\r\n
\u2022 Your dentist may have records showing exactly what material was used, which is handy if the MRI team asks.<\/p>\r\n
\u2022 A loose or damaged bridge deserves attention anyway, especially if you’ve noticed movement or discomfort.<\/p>\r\n
Usually, no. A fixed dental bridge isn’t like a removable denture that you can simply take out before entering the MRI room. Trying to remove a properly fitted bridge just for an MRI would be unnecessary in most situations.<\/p>\r\n
The trick is to let the MRI team make the call based on the bridge and the scan you’re having. They deal with MRI safety all day, and they’ll know what information matters.<\/p>\r\n
