Can you have an mri if a dental crown?

In general, it is safe to have an MRI (Magnetic Resonance Imaging) scan with a dental crown. Dental crowns, which are types of dental restorations, typically do not interfere with the magnetic fields used in MRI machines.

Here are some points to consider regarding MRI and dental crowns:

1. Non-Metallic Crowns: Dental crowns that are made of non-metallic materials, such as porcelain or ceramic, do not pose any concerns during an MRI scan. These materials are MRI-compatible and do not produce any artifacts or distortions in the MRI images.

2. Metal Crowns: Dental crowns that contain metallic components, such as those made from gold, amalgam, or certain alloys, may cause artifacts on the MRI images. However, these artifacts are usually minimal and do not significantly affect the overall quality of the MRI scan. In most cases, having a metal crown does not prevent you from undergoing an MRI.

3. Consultation with the Radiologist: If you have concerns about your dental crowns and an upcoming MRI scan, it's advisable to consult with both your dentist and the radiologist who will conduct the MRI. They can provide specific advice based on your individual situation.

4. Special Considerations: If you have a dental crown with a large metallic component near the area being imaged, or if you have a history of significant metallic artifacts in previous MRIs, the radiologist may recommend alternatives such as using different imaging techniques or taking special precautions during the scan to minimize artifacts.

It is always important to inform your healthcare provider, including the radiologist, about any dental restorations or implants you have before undergoing an MRI scan. This allows them to make appropriate adjustments and provide the best possible imaging experience.
