Braces and MRIs: A Magnetic Mix or a Safe Scan?

Most modern braces, including metal, ceramic, and clear aligners, are considered safe for MRI scans. While metal braces may cause minor image artifacts, they typically won’t be pulled out or cause harm. Always inform your doctor and the MRI facility about your braces before the scan so they can take any necessary precautions.

What is an MRI?

Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool that creates detailed images of the body’s internal structures. It generates these images using a strong magnetic field and radio waves, allowing doctors to diagnose various conditions, from brain injuries to joint problems.

The Concern: Metal and Magnets

The primary concern regarding braces and MRIs is that traditional braces are made of metal. MRI machines use powerful magnets, and there’s a natural concern about how these magnets might interact with metal braces. Will the braces be pulled out? Will they heat up? These are common anxieties.

Are Dental Braces Safe for MRI?

The good news is that, in most cases, dental braces do not pose a significant risk during an MRI scan. While it’s true that braces are made of metal, the materials used in modern orthodontic appliances are typically non-ferrous, meaning they are not strongly attracted to magnets. This should reassure you about the safety of your braces during an MRI.

• Traditional Metal Braces contain metal, but the alloys used are generally considered MRI-safe. They may cause minor image artifacts (distortion) but won’t be pulled out or cause significant harm. This reassurance should reinforce your sense of security and trust in your orthodontic treatment.
• Ceramic Braces are made of tooth-colored ceramic material and are entirely non-metallic. They are safe for MRIs.
• Invisalign and Other Clear Aligners are plastic and entirely safe for MRI scans. However, you will typically be asked to remove them before the scan.

Why Does the Concern Persist?

The lingering concern about braces and MRIs often comes from older information or a general misunderstanding of the materials used in modern orthodontics. It’s important to note that years ago, some orthodontic appliances contained more ferrous metals, which could indeed pose a risk. However, contemporary orthodontic materials have evolved, and the risk is minimal. This evolution in materials should make you feel informed and up-to-date about your orthodontic treatment.

Potential Issues and How They’re Addressed?

While generally safe, there are a few potential issues to be aware of:

• Image Artifact: Metal braces, mainly traditional metal braces, can sometimes create minor image artifacts or distortions in the MRI scan, especially in areas close to the mouth. This is usually not a significant problem for diagnostic purposes, but your radiologist should be aware of it. They may adjust the scan parameters to minimize any interference.
• Minor Warmth: Some patients might experience a slight warming sensation in their braces during an MRI. This is usually minimal and not harmful.

What to Do Before Your MRI?

• Inform Your Doctor and Radiologist: It’s crucial to inform your doctor, who is ordering the MRI, and the facility staff that you have braces. This allows them to take necessary precautions or adjust the required scan parameters.
• Know Your Braces Type: If you’re unsure what braces you have, check with Toombs Orthodontics. Knowing the materials your braces are made of can help the MRI staff make informed decisions.
• Remove Removable Appliances: If you wear removable retainers or aligners such as Invisalign), you must remove them before the MRI scan.
