Is it okay to have a brain CT scan with metal dental braces in the mouth?

In general, it is acceptable to undergo a brain CT scan if you have metal dental braces in your mouth. Details are as follows:

Typically, metal dental braces may interfere with MRI (magnetic resonance imaging) results, primarily because metallic materials can interact with the magnetic field used in MRI, causing distortion and imbalance in the field and compromising image accuracy. However, brain CT scans rely on X-rays for imaging, and metal braces in the mouth do not significantly affect X-ray transmission or compromise the accuracy of the results. Therefore, individuals with metal dental braces can safely undergo brain CT scans.

It is important to note that prior to undergoing a brain CT scan, healthcare providers should conduct a professional assessment of the patient. Because CT scans involve ionizing radiation, pregnant women and those planning pregnancy should avoid this procedure whenever possible, as radiation exposure may pose risks to both the mother and fetus. During the examination, patients should strictly follow medical instructions, cooperate fully with healthcare staff, remain as still as possible, and avoid any head movement that could compromise image quality. Additionally, patients should not wear metallic accessories on the head during the scan.
