Are Dental Braces Safe for MRI?

Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool that uses strong magnetic fields and radio waves to create detailed images of the body’s internal structures. It’s invaluable for diagnosing a wide range of medical conditions. However, if you have dental braces, you might wonder, “Are they safe for an MRI?” 

Understanding the Concerns: Metal and Magnets

The primary concern regarding braces and MRIs stems from traditional braces being made of metal. MRI machines use powerful magnets, and metal objects can be attracted to these magnets. This raises legitimate questions about the potential for braces to be pulled or moved during an MRI scan, causing discomfort or even injury.

The Good News: Most Modern Braces Are MRI-Safe

The vast majority of modern braces in Pompano Beach, FL, including those used at Lighthouse Point Orthodontics, are made from materials that are considered MRI-safe.  This means they are either non-magnetic or weakly magnetic and, therefore, unlikely to be significantly affected by the MRI’s magnetic field. These materials include:

• Stainless Steel: Stainless steel is a metal; the specific alloys used in orthodontic braces are generally considered MRI-safe. They may cause minor image artifacts (distortion), but the magnet won’t forcefully pull them.
• Titanium: Titanium is a non-magnetic metal often used in orthodontic appliances, including some types of braces. It’s entirely safe for MRI scans.
• Ceramic: Ceramic braces are non-metallic and pose no risk during an MRI.
• Clear Aligners (like Invisalign): Clear aligners are made from thermoplastic material and are entirely MRI-safe. However, you’ll need to remove them before the MRI.

While most modern braces are MRI-safe, there are a few factors that can influence the situation:

• Type of Braces: As mentioned above, the most crucial factor is the material of your braces. Older braces made with certain types of ferromagnetic materials might pose a risk, but these are less common today.
• Strength of the MRI Magnet: MRI machines have different magnetic field strengths, measured in Tesla (T). The stronger the magnetic field, the greater the potential interaction with any metal. While most modern braces are safe for standard MRI strengths (typically 1.5T and 3T), it’s always best to inform your orthodontist and the MRI technician about your braces.
• Location of the Braces: While unlikely, if a metal component of the braces is very close to a sensitive area of the body being imaged, it might cause some image distortion. This is usually not a significant concern, but it’s worth mentioning to the MRI technician.
• Other Orthodontic Appliances: If you have other orthodontic appliances, such as retainers, expanders, or temporary anchorage devices (TADs), in addition to braces, it’s essential to discuss these with your orthodontist and the MRI technician, as some may need to be removed before the scan.

What to Do If You Need an MRI with Braces?

If you need an MRI and you have braces, here are the steps you should take:

1. Inform Your Orthodontist: Let your orthodontist at Lighthouse Point Orthodontics know you need an MRI. They can confirm the type of braces you have and provide you with any necessary information about their MRI compatibility. They may even be able to give the MRI facility a letter confirming the materials used in your braces.
2. Inform the MRI Facility: When you schedule your MRI, inform the facility that you have braces. They will likely ask you about the type of braces you have and may have specific protocols in place for patients with orthodontic appliances. Providing them with the information from your orthodontist is very helpful.
3. Follow the MRI Technician’s Instructions: The MRI technician will guide you through the process and provide any specific instructions regarding your braces. They may ask you to remove any removable appliances, like retainers or aligners.
4. Don’t Worry Excessively: In most cases, having braces will not prevent you from having a necessary MRI. Modern braces are generally safe, and the MRI facility is well-equipped to handle patients with orthodontic appliances.
