MRI with braces: screening, images and what to ask

An MRI appointment can raise a question you had never considered when starting orthodontic treatment: what happens to the metal in your mouth? Contact the imaging center when the scan is arranged. Early information gives its team time to clarify what it needs from you and your orthodontist.

Why does the MRI team need to know?

MRI uses strong magnetic fields and radiofrequency energy. The FDA explains that some devices can move, heat or interfere with an examination. These are reasons for screening, not a prediction that your braces will cause an injury. A device described as MR Conditional is suitable only under its specified conditions; do not interpret that label as unrestricted permission.

The FDA places the individual risk-benefit assessment with the responsible physician, typically the radiologist. Your orthodontist can help identify the appliance, while the imaging service determines how it fits the planned scan. An online answer or another patient’s experience cannot provide that clearance.

What should you tell the imaging center?

Complete the screening form accurately and tell the MRI technologist about devices or implants. The FDA recommends bringing an implant card if you have one. If you do not know an appliance’s name or material, say so and ask what documentation the center needs.

• Describe what you wear: fixed braces, a bonded retainer, an expander, or a removable aligner or retainer.
• Mention additional dental work or devices you know about, including implants or jaw hardware.
• Provide the treating orthodontist’s contact details and the scan date.
• Report anything that feels loose, damaged or uncomfortable.
• Ask where the office should send requested device information.

If you have a dental implant, the FDA specifically advises notifying imaging professionals before MRI, because implants can interfere with images. Include that information even when the appointment was prompted by your braces.

Safety and clear images are separate questions

Metal can produce an artifact: distortion or missing detail in the picture. RadiologyInfo notes that braces and retainers may affect images of the face or brain. An artifact is an imaging problem; its presence alone does not mean the appliance has harmed you. Ask whether it could obscure the particular area the doctor needs to assess.

Cincinnati Children’s explains that different imaging techniques or angles can sometimes improve pictures affected by orthodontic hardware. In some cases, a device may need professional removal. That decision should follow discussion among the referring clinician, radiologist and patient or parent, with the orthodontist involved in any appliance work.

A friend’s knee scan does not settle the question for your brain scan. Ask two clear questions: Can this appliance remain for the planned examination? Will the resulting images answer the clinical question? If the answer is uncertain, ask which team will resolve it before the appointment.

What about clear aligners and permanent retainers?

Describe the full setup, including any bonded wire behind the teeth. Ask the MRI team exactly which removable items to take out and when to do so. Bring their usual storage case. If instructions seem to conflict with your orthodontic wear schedule, ask the two teams to clarify the plan.

For a fixed retainer, our retainer removal guide explains why removal belongs with a dental professional. Do not pull off brackets, cut wires or remove a bonded appliance yourself to prepare for a scan.

If an appliance change is requested

Ask the imaging service to specify the requested change and the reason, rather than relaying a vague instruction to “remove the metal.” Share that request with your orthodontist. For appointments in Valencia or elsewhere in Santa Clarita, confirm the order of visits before taking time away from school or work.

• Is the request about safety, image quality, or both?
• Which component needs attention, and who confirmed the request?
• When must the scan happen, and who coordinates any timing changes?
• What orthodontic follow-up, replacement or retention plan is needed afterward?
• Are there separate charges for appliance removal and replacement?

What if the scan is urgent?

Tell the medical and radiology teams about your appliance immediately. Do not postpone an urgent scan on your own while waiting for routine orthodontic contact. RadiologyInfo explains that delaying or missing imaging can delay diagnosis. The medical team should decide how to manage the scan’s urgency and any device concerns.

On the day of your MRI

Follow the imaging center’s preparation instructions and repeat any unanswered appliance questions before entering the scanner room. The FDA encourages asking how to alert the technologist to a problem. Make sure you know how to call for help. Report pain, heat or other unusual discomfort promptly rather than waiting for the scan to finish.

Keep a copy of any appliance information obtained for this visit. If another scan is arranged later, tell that imaging service what you currently have and ask what it needs. Record any agreed orthodontic follow-up alongside the scan appointment so it is easy to find.
