Can You Have an MRI With Dental Implants?
In most cases, you can have an MRI with dental implants. Modern dental implants are usually made from titanium or zirconia, and both materials are generally considered compatible with MRI.
The bigger issue is often image quality, not safety. Metal in the mouth can sometimes distort the scan, especially when the MRI is focused on the head, face, jaw, or neck.
That said, not every dental metal object behaves the same way. An implant post in the jaw is different from a removable denture, an older bridge, orthodontic hardware, or a magnetic attachment used with some overdentures.

Why Dental Implants Are Usually MRI-Compatible
MRI uses a strong magnetic field and radiofrequency energy to create images. Many people worry that any metal in the body will be pulled or shifted, but that concern does not apply equally to all metals.
Most dental implants are made of titanium. Titanium is not ferromagnetic, which means it is not strongly attracted to a magnet the way iron-containing metals can be.
Some implants and implant components may also involve zirconia or titanium alloys. These materials are widely used because they are durable, biocompatible, and generally stable in MRI settings. If you prefer a metal-free option, ask your dentist about porcelain implants.
Once a dental implant has healed into the jawbone, it is also mechanically fixed by bone integration. This process is called osseointegration, meaning the bone has fused tightly to the implant surface. If you want to learn more about how long implants last, read about dental implant longevity.
Because of that combination of material properties and firm fixation, modern dental implants are usually not a reason to cancel an MRI. The final decision still belongs to the radiology team, especially when there are multiple devices or unclear records.
What Can Still Be a Problem During MRI
The most common issue is artifacts. Artifact means a shadow, blur, or distortion on the MRI image that can make nearby anatomy harder to interpret.
This matters most when the scan is of the brain, sinuses, jaw joints, oral cavity, salivary glands, or upper neck. A knee or lumbar spine MRI is much less likely to be affected by a dental implant.
When Do Dental Implants Affect MRI Image Quality?
The amount of distortion depends on several factors. These include the implant material, the size and shape of the hardware, the MRI technique, and how close the area of interest is to the implant.
A single implant in the back of the mouth may cause little trouble for many scans. Multiple implants, implant bars, full-arch metal restorations, or dense metal crowns can create more noticeable interference.
For example, all-on-4 implants may create more artifacts because of the amount of metal involved. Patients with extensive tooth loss or full-arch restorations may also want to learn more about full-mouth implants if they are discussing long-term treatment planning with their dentist.
So the question is not only whether the MRI is safe. It is also whether the images will be clear enough to answer the medical question. Studies on dental material artifacts show that some dental materials can obscure nearby anatomy on MRI.
Dental Hardware That Deserves Extra Attention
A standard implant fixture in bone is usually straightforward. Other dental hardware may need more discussion with the imaging center before the scan.
Examples include magnetic overdenture attachments, some older implant components, certain orthodontic appliances, removable partial dentures with metal frameworks, and less common maxillofacial reconstruction hardware. These items are not automatically unsafe, but they may need case-by-case review.
If you are unsure what type of dental work you have, contact the dentist or oral surgeon who placed it. The office may be able to provide an implant card, chart note, or manufacturer information.
That detail can save time on the day of the scan. It also helps the MRI team decide whether any adjustment is needed before imaging begins.
What to Tell the MRI Center Before Your Scan
Tell the MRI center if you have any dental implants, implant-supported bridges, dentures, crowns, braces, retainers, or oral surgery hardware. If something is removable, mention that too.
Useful details include when the work was done, which side of the mouth it is on, and whether you know the material. If the scan is for the head or neck, this information becomes even more important.
Many imaging centers use a screening form before MRI. Fill it out carefully, and do not assume that dental hardware is too minor to mention.
If the staff wants more information, they may contact your dentist. That is normal and often helps avoid last-minute rescheduling.
Will You Need to Remove Anything?
A dental implant that is surgically fixed in the jaw is not something you remove for MRI. The same is true for most implant fixtures that have healed normally.
Removable items are different. Dentures, removable partials, orthodontic retainers, night guards with metal parts, and some snap-on implant prostheses may need to be taken out before the scan.
This is partly a safety issue and partly an image-quality issue. Even when an item is not dangerous, removing it may reduce artifacts and improve the usefulness of the MRI.
The imaging staff will tell you what should stay in and what should come out. Follow their instructions rather than making assumptions at home.
When You Should Ask More Questions
A few situations justify a closer look before MRI. One is when you do not know what type of implant or attachment you have, especially if it was placed many years ago or outside the United States.
Another is recent oral surgery. Fresh surgical sites, temporary components, or combined facial hardware may need clarification even if the implant itself is expected to be MRI-compatible.
You should also ask more questions if you have pain, loosening, swelling, or suspected implant failure. Those symptoms do not necessarily make MRI unsafe, but they may point to a separate dental problem that needs evaluation.
If the MRI is being ordered for a condition near the jaw or face, it is reasonable to ask whether dental metal could limit the study. In some cases, the radiologist can adjust the scan technique or recommend a different imaging test.
Red Flags That Need Prompt Dental or Medical Follow-Up
Seek prompt dental or medical care if you have rapidly increasing facial swelling, fever, trouble swallowing, trouble breathing, uncontrolled bleeding, or severe worsening pain. These are urgent red flags and may point to infection or another serious problem.
Also get evaluated if an implant feels mobile, your bite suddenly changes, or you have persistent numbness in the lip, chin, or tongue. Those findings are not normal and should not wait for a routine visit.
An MRI appointment should not delay care for an active dental emergency. If symptoms are significant or worsening, contact a dentist, oral surgeon, or urgent medical service based on severity.
How Dentists and Radiology Teams Usually Handle This
In real practice, this is usually a documentation and planning issue. The radiology team screens for implanted devices, and the dental office may confirm the type of implant if records are needed.
If the implant is a standard modern system, the scan often proceeds as scheduled. If there is concern about image distortion, the radiologist may still move forward but note that the study has technical limitations.
That distinction matters. A scan can be safe yet less useful for a very specific question near the mouth or skull base.
Plan Ahead for a Smoother MRI Experience
From a patient perspective, the best move is early disclosure. Mention dental implants when the MRI is booked, not only when you arrive.
That gives the team time to review the details and helps prevent same-day delays. If you are unsure what kind of implant or dental hardware you have, your dentist can usually help identify it before the imaging visit.

FAQs
Can a titanium dental implant move during an MRI?
In most cases, no. Titanium is not strongly attracted to the MRI magnet, and a healed implant is anchored in bone.
Can dental implants ruin an MRI scan?
They usually do not ruin the scan, but they can create artifacts near the mouth, jaw, or face. Whether that matters depends on what body part is being imaged.
Are zirconia implants safer than titanium for MRI?
Both are generally considered compatible with MRI. The practical difference is often less about safety and more about how much image distortion occurs in a specific scan.
Should I tell the MRI center about a single dental implant?
Yes. Even one implant should be disclosed on the screening form so the imaging team has a complete record.
Can I have a brain MRI with dental implants?
Often, yes. The main concern is whether the implant causes an artifact that affects the area the radiologist needs to see.
Do dentures or removable implant teeth need to come out?
Sometimes. Removable dental items are commonly taken out before MRI, especially if they contain metal or could affect image quality.
