Are Dental Implants Safe for MRI? A Comprehensive Guide for Patients
MRI and dental implants—two words that make a lot of people nervous. If you’ve ever wondered whether your smile will mess up a scan or put you at risk, you’re not alone! This article has the plain answers you’re looking for. Read on to discover why dental implants are generally safe for MRI, what you should tell your doctor, and how to be ready for your next scan.

What Is an MRI, and Why Is Metal a Problem?
Let’s start with the basics. MRI means magnetic resonance imaging. In simple words, it’s a strong test that doctors use to look inside your body without opening you up. It uses a big magnet and radio waves.
Why do people worry about metal? The magnet inside an MRI is much, much stronger than the ones on your fridge. If a piece of metal is the wrong kind, the MRI could pull on it, heat it up, or even make the scan picture blurry. That sounds scary, right? But not all metals act the same way in magnetic fields. Some stick to magnets, and some don’t.
Problem: You might worry that metal in your mouth could move or get hot during a scan.
Worry: What if it does? Could it hurt you or mess up your test?
Answer: Keep reading. Most dental implants use stuff that is safe and don’t react to the MRI, but it helps to know what’s in your mouth!
What Makes Dental Implants Different from Other Metal?
Not all dental work is the same. Some old fillings and braces have metals that act differently in strong magnets than the metals used in most dental implants today.
Dental implants are small posts or screws that the dentist puts in your jaw to hold new teeth. What matters most is the material. Most are made from titanium, some from zirconia (a kind of ceramic), and a few old ones from stainless steel or cobalt-chromium.
Check out this quick table:
| Material Type | Magnetic? | MRI Risk Level | Used Today? |
|---|---|---|---|
| Titanium / Titanium Alloy | No (not magnetic) | Low | Yes, 90%+ |
| Zirconia (ceramic) | No | None | Yes, growing |
| Stainless Steel, Cobalt-Chromium (old) | Yes | High | Rare |
Are Titanium Implants Safe for MRI?
This is the big question. Modern titanium dental implants are a little bit magnetic, but not enough to matter. In plain talk, they don’t really “care” about a magnetic field. It’s like putting a plastic bottle near a magnet—nothing happens.
My dentist once showed me a titanium implant. He held a magnet to it, and nothing happened. It stayed put, and that’s just how it would act in an MRI. Studies show that these implants don’t get hot enough to be dangerous during a scan, and they don’t move.
Even the FDA and groups like the American Dental Association (ADA) and American College of Radiology (ACR) say: modern titanium implants are safe for MRI. You’re more likely to set off a metal detector at the airport than have trouble in an MRI.

What About Zirconia Implants?
Zirconia might sound fancy, but think of it as really strong, non-metal stuff—doesn’t care about magnets at all. It’s a type of ceramic, and it simply doesn’t react in an MRI. No heating, no moving, and actually, zirconia implants make better MRI pictures since they don’t mess up the view.
So if you have a zirconia implant, you can relax—no MRI worries here. These are especially liked by people who want no metal in their mouth.
Could My Dental Implant Cause Problems in an MRI?
Here’s what most people worry about. For almost everyone with modern dental implants, there are only two things to think about:
1. Will It Move?
No. Implants are stuck in your jawbone; titanium and zirconia aren’t affected by the MRI magnet.
2. Will It Get Hot?
Tests show only a tiny rise in heat (less than 2°C). Your morning coffee is way hotter than that.
3. What About Odd Feelings or Pain?
Very rarely, someone might feel a little warmth or tingling, but it’s not dangerous and goes away fast.
4. What About Old Implants?
If your implant is really old (before the 1990s) or made from steel or some other strong magnetic metal, stop and tell your doctor—don’t keep quiet!
Common Issues Table
| Issue | How Common? | What Could Happen | Who Should Worry? |
|---|---|---|---|
| Heating | Very rare | Slight warmth | Not really a problem |
| Movement | Extremely rare | Not seen in modern implants | Only very old steel ones |
| MRI Image Artifact | Common | Blurry spot near the implant | Head/neck MRI, not body |

How Can I Minimize Risks Before My Scan?
Here’s an easy checklist:
Tell your doctor and MRI team about your dental work. If you have an implant card or dental paper, take it with you. If not, call your dentist—they can help.
Let them know:
- What kind of implant you have (titanium, zirconia, etc.)
- Which tooth or teeth have implants
- If you don’t know, just say so. It’s always better to check!
Mention any other dental work—like braces or old metal crowns. This lets the MRI team adjust things to keep you safe and get the best pictures.
Are There Cases Where MRI Is Not Safe with Dental Implants?
Most new dental implants, especially those put in after the 1990s, are safe. Still, there are rare times when an MRI is not a good idea.
Old steel or cobalt-chromium implants: These were put in years ago. They can be pulled by an MRI magnet and might even move a little—not good.
Loose, not healed implants: If you just had surgery and the implant isn’t “set” in your jaw yet, your doctor might ask you to wait before any scans.
Most people reading this don’t need to worry. But if you’re not sure, ask your dentist or oral surgeon. Our digital dental lab team helps dentists spot these cases fast.
What Do Experts and Guidelines Say?
Good question! You don’t have to trust just me. Here’s what top experts and groups say:
American College of Radiology (ACR):
Most dental implants today are MRI conditional. That means they’re safe as long as you follow the normal rules—just let your medical team know.
Food and Drug Administration (FDA):
Implant companies must prove their products are safe for MRI before they can sell them. That little titanium post in your jaw passed some serious safety tests!
Research:
Studies show titanium and zirconia implants don’t move or get hot in MRI scans, and problems are super rare.
Quick tip: The main thing isn’t your safety—it’s that metal in your mouth can blur part of the MRI image.
How Do Dental Implants Affect MRI Image Quality?
Some doctors forget about this. Implants, especially metal ones, can mess up the scan picture right around your mouth or jaw. Radiologists call these “artifacts”—big white or black spots where the machine can’t see past the implant.
But:
- If it’s a shoulder or body MRI, dental implants don’t matter at all.
- Head or neck scans? You might see blurry spots next to the implant. The MRI team may change settings to work around this.
- Ceramic implants leave smaller blurry spots than metal ones.
Just make sure your doctor knows about your dental work!
What Should I Tell My Doctor or Dentist?
This is super important! If you remember one thing, remember to always tell your doctor if you have dental implants before you get an MRI.

Conclusion: Putting Your Mind at Ease
If you’ve read this far, the answer is simple: modern dental implants are safe for MRI. Titanium and zirconia don’t move, don’t get hot. The worst thing that happens is a blurry spot on the picture, but doctors usually work around it.
But, always tell your medical team about any implants, especially if your dental work is old or you aren’t sure what’s in your mouth. Being open is the best safety tool you have.
