If you have dental implants and your doctor recommends an MRI scan, you may wonder whether the two are compatible. It’s a common concern because MRI machines use powerful magnetic fields, and many people assume that metal dental implants could pose a risk.
The good news is that in most cases, you can safely undergo an MRI with dental implants. Modern dental implants are designed using biocompatible materials that are generally considered safe in MRI environments. However, there are a few important considerations regarding image quality, implant materials, and communication with your healthcare providers.
In this guide, we’ll explain how MRI scans work, whether dental implants affect MRI safety, and what patients should know before their appointment.
What Is an MRI?
MRI stands for Magnetic Resonance Imaging.
It is a diagnostic imaging technique that uses the following:
- Powerful magnets
- Radio waves
- Computer technology
to create detailed images of internal structures such as
- Brain
- Spine
- Joints
- Organs
- Soft tissues
Unlike X-rays and CT scans, MRI does not use ionizing radiation.
Can You Have an MRI with Dental Implants?
Quick Answer
Yes.
Most modern dental implants are MRI-safe and do not prevent patients from undergoing MRI scans.
Dental implants are typically made from titanium, which is a non-ferromagnetic metal. This means it is not strongly attracted to magnetic fields and generally does not pose a safety risk during MRI examinations.
Millions of patients with dental implants safely undergo MRI scans every year.
What Materials Are Dental Implants Made From?
Most dental implants are manufactured using:
Titanium
Titanium is the most common implant material because it is:
- Strong
- Lightweight
- Corrosion-resistant
- Biocompatible
- Non-ferromagnetic
Titanium is widely used in medicine, including the following:
- Dental implants
- Joint replacements
- Bone fixation devices
Zirconia
Some implants are made from zirconia, a ceramic material.
Benefits include:
- Metal-free construction
- Excellent aesthetics
- MRI compatibility
Zirconia implants are also considered safe for MRI procedures.
Why Dental Implants Usually Do Not Affect MRI Safety
MRI safety concerns generally involve ferromagnetic metals such as the following:
- Iron
- Nickel
- Cobalt
These materials may:
- Move within magnetic fields
- Heat up
- Distort images
Dental implants are different.
Because titanium is non-ferromagnetic, it typically:
- Does not move during MRI
- Does not become dangerous
- Remains securely integrated within the jawbone
This makes modern implants safe for MRI examinations.
Can Dental Implants Affect MRI Images?
While dental implants are generally safe, they can occasionally create imaging artifacts.
What Are MRI Artifacts?
Artifacts are distortions or shadows that may appear on MRI images.
These artifacts can:
- Reduce image clarity
- Obscure nearby structures
- Affect diagnostic accuracy in specific areas
The likelihood depends on:
- Implant material
- Implant size
- MRI strength
- Area being scanned
When Can Dental Implants Cause Imaging Issues?
Artifacts are most noticeable when the MRI is focused near the mouth, face, or head.
Examples include:
Brain MRI
Most brain MRIs remain diagnostic despite dental implants.
TMJ MRI
Temporomandibular joint imaging may occasionally be affected.
Facial Imaging
Artifacts may interfere with visualization of nearby structures.
Neck Imaging
Depending on implant location, image distortion may occur.
Radiologists can often adjust scanning techniques to minimize these effects.
Should You Tell the MRI Technician About Dental Implants?
Absolutely.
Before undergoing an MRI, inform the following:
- MRI technologists
- Radiologists
- Referring physicians
Provide information about:
- Dental implants
- Implant-supported dentures
- Orthodontic appliances
- Crowns
- Bridges
This allows the imaging team to plan accordingly.
Are Older Dental Implants MRI-Safe?
Most dental implants placed over the past several decades are MRI-compatible.
However, older restorations may contain:
- Mixed metal alloys
- Magnetic components
- Unknown materials
If you’re unsure about your implant material:
- Contact your dentist
- Request implant records
- Inform the MRI facility
Additional evaluation may be recommended.
What About Other Dental Restorations?
Dental Crowns
Most crowns are MRI-safe.
Dental Bridges
Typically safe but may create minor artifacts.
Dentures
Removable dentures should usually be removed before scanning.
Orthodontic Braces
Braces are generally safe but may significantly affect image quality, particularly in head and neck scans.
Retainers
Your imaging team will advise whether removal is necessary.
MRI Safety and Dental Implant Success
Many patients worry that MRI machines might loosen or damage implants.
Fortunately, this is not the case.
A properly integrated dental implant is securely fused to the jawbone through a process called osseointegration.
MRI scans do not:
- Loosen implants
- Damage implants
- Affect implant function
- Interfere with osseointegration
Patients can safely continue normal implant care after an MRI.
Questions to Ask Before Your MRI
If you have dental implants, consider asking:
- Will my implants affect image quality?
- Should I bring implant records?
- Is my implant material MRI compatible?
- Do I need to remove any dental appliances?
- Are alternative imaging methods necessary?
Open communication helps ensure the best diagnostic results.
Common Myths About MRI and Dental Implants
Myth #1: Dental Implants Will Be Pulled Out During an MRI
Fact: Modern titanium implants are not strongly magnetic and remain safely fixed in the jawbone.
Myth #2: MRI Scans Damage Dental Implants
Fact: MRI scans do not harm dental implants or affect their longevity.
Myth #3: You Cannot Have an MRI If You Have Dental Work
Fact: Most modern dental restorations are MRI-compatible.
Myth #4: Dental Implants Always Ruin MRI Images
Fact: While minor artifacts can occur, modern imaging techniques often minimize their impact.
Frequently Asked Questions
Can titanium dental implants go in an MRI?
Yes. Titanium implants are generally considered MRI-safe.
Will an MRI damage my dental implants?
No. MRI scans do not damage properly placed dental implants.
Can dental implants affect brain MRI results?
Minor artifacts are possible, but most brain MRIs remain diagnostic and useful.
Should I remove implant-supported dentures before an MRI?
Your imaging provider will advise based on the type of restoration.
Can zirconia dental implants be used with MRIs?
Yes. Zirconia implants are considered MRI compatible.
Conclusion
So, can you get an MRI with dental implants?
In most cases, the answer is yes. Modern dental implants made from titanium or zirconia are generally MRI safe and do not pose a risk during imaging procedures. While minor image artifacts may occasionally occur, especially during head and neck scans, dental implants rarely prevent patients from receiving important diagnostic imaging.
The best approach is to inform your MRI team about your dental implants before the scan. With proper communication and planning, most patients with dental implants can safely undergo MRI examinations without complications.
