ImplantPPCCan You Get an Mri with a Dental Implant
Yes, most people with dental implants can still get an MRI. That's the short version, and for implants placed in the last couple of decades, it holds up.
What trips people up is mixing two separate questions into one. First: is the implant safe inside that big magnet? Second: will the implant mess up the pictures? Those are different problems with different answers. The first one is almost always a calm yes. The second one is real, but manageable.
There's a third thing too, and it catches people off guard — anything in your mouth that comes out. A partial denture, a retainer, a night guard. None of that has anything to do with your implant, and all of it has everything to do with what you hand over before you walk into the scan room.
The short answer: implants and MRI scanners usually get along fine
An MRI doesn't use X-rays. It uses a very strong magnet and radio waves to build pictures of what's inside you. That magnet is why you get asked about metal — pacemakers, surgical clips, metal fragments, that sort of thing. Some of that hardware can genuinely be dangerous in a scanner.
Dental implants aren't in that group.
Most implants today are made of titanium or zirconia, and both are generally safe for MRI scans. Titanium is a non-magnetic metal, so the scanner's magnet doesn't pull on it or heat it up. Zirconia is a ceramic, which means there's no metal involved at all.
You also won't find a list of dental implant types that are automatically off-limits for MRI. The tricky metal cases tend to come from other parts of the body, not your jaw.
Still — and this matters — safe for you isn't the same as invisible to the machine. Hold that thought.
Why titanium and zirconia stay out of the magnet's way
Think about what an MRI magnet actually does. It doesn't care about metal in general. It cares about *magnetic* metal — iron, some steels, a few alloys. Those get pulled, twisted, or heated.
Titanium isn't magnetic. That's the whole reason it's used for implants, joint replacements, and bone plates in the first place. Zirconia isn't metal at all, so there's nothing for the magnet to grab.
So an implant sitting in your jaw isn't going anywhere and isn't heating up. That part of the story is boring, in the best possible way.
But here's the catch that connects the safety question to the picture question: even non-magnetic metal can disturb the magnetic field around it. Not enough to hurt you. Enough to leave a smudge on the image.
Can the magnet pull an implant loose or make it hurt?
No. If the implant is titanium or zirconia, the magnet has nothing to pull on. That's the appeal of those materials.
And keep in mind what an implant actually is. Once it's healed, it's fused to the bone in your jaw. It's not a loose screw rattling around in there, and the scanner can't unscrew it.
That said, if an implant already feels loose, wobbly, or sore before your scan, say so when you check in. Not because the MRI will make it worse, but because it's useful information — and because a loose implant is a dental problem worth getting looked at either way. Your dentist handles that, not the MRI technologist.
If you feel anything unusual during the scan itself, use the intercom and tell the technologist. That's what it's there for.
What implants can do to the picture itself
This is where the real, practical downside lives. Not safety. Pictures.
Implants can cause minor image distortion or reduce clarity in the area right around them. Metal doesn't block the scan so much as smear it a little, like a smudge on a window. Usually it's a small patch, and radiologists see it constantly — they know how to read around it.
Older implants may blur the image more than newer ones do. The material and design of older hardware isn't always as scanner-friendly.
So when does it actually matter? When the thing your doctor wants to look at is right next to the implant. If you're getting your jaw, mouth, sinuses, or face scanned, that distortion sits in the middle of the area of interest. If you're getting a knee scanned, nobody cares.
You can't fix this yourself, and you shouldn't try. What you *can* do is make sure the imaging team knows the implant is there before the scan is planned, so they're not surprised by what shows up.
Crowns, bridges, fillings, and the stuff that comes out
Here's the distinction the internet tends to blur: fixed dental work versus removable dental work.
Fixed things — crowns, bridges, fillings, root canal posts, bone graft hardware — are cemented or bonded in place. They generally follow the same rule as implants. Usually safe, sometimes a source of image distortion, especially if they're metal. You don't take them out, and you shouldn't try.
Removable things are a different story entirely. Some prostheses and appliances should come out before an MRI, and the research on this is fairly clear about it. That list usually includes:
- Partial dentures and dentures with metal clasps
- Retainers and clear aligners
- Night guards and bite splints
- Anything else you can take out of your own mouth
The good news: if you can pop it out yourself, you can solve that problem in ten seconds. Just tell the technologist it exists, then hand it over.
What to tell the MRI technologist before the scan
This is the part that actually protects you and your scan. Skip the guesswork and just disclose everything. Run through this list out loud or on the screening form:
- The implant itself — that you have one, roughly where, and when it was placed if you know.
- Every fixed restoration — crowns, bridges, fillings, posts, anything cemented in.
- Every removable appliance — dentures, partials, retainers, guards.
- Past oral or jaw surgery — plates, screws, wires, grafts.
- Anything loose, sore, or recently placed.
- Any paperwork from your dentist describing the implant material.
If you have a card or record from your implant dentist listing the material, bring it. That single piece of paper ends the guessing.
Then ask the one question that matters: *does anything in my mouth need to come out before I go in?*
If your implant is old, loose, or a mystery
Old implants are the ones most likely to affect image clarity, so they're worth flagging even if everything feels fine. Don't assume the team will figure it out from the scan.
If you have no idea what your implant is made of, say exactly that. "I don't know" is a useful answer. A guess isn't — it can send the screening in the wrong direction. Your implant dentist or the practice that placed it may have records, and it's worth asking before scan day rather than scrambling on the morning of.
If the implant feels loose or painful, tell the MRI team *and* call your dentist. Two separate people, two separate concerns. And never try to remove or adjust a fixed implant or restoration yourself — that's a job for a dental professional, not a screwdriver and not a nervous Tuesday night.
Common questions about implants and MRI
What if my implant isn't titanium or zirconia? There isn't a specific dental implant type that's known to be incompatible with MRI. The standard advice still applies: tell the technologist what you have and let them make the call along with the radiologist.
How do people with implants actually get scanned? The same way anyone else does. They show up, fill out the screening form, mention the implant and any other dental work, and get scanned. The disclosure is the whole trick.
Is there metal in an implant that the magnet cares about? Titanium, the most common implant material, isn't magnetic. So no pull, no heat. The implant may still throw off a bit of image distortion, which is a picture problem, not a safety problem.
Can I get an MRI with metal on my teeth? Metal in your mouth doesn't automatically cancel the scan. What it does is make the disclosure step non-optional — past dental treatment is relevant to the MRI team, and some removable appliances need to be taken out first.

Your best move is a phone call before the appointment, not a conversation in the changing room. Ring the MRI facility, tell them about every implant, crown, bridge, filling, plate, and removable appliance you have, and ask whether anything needs to come out. Then do the same thing again when you arrive, because the screening form isn't a formality — it's the reason the scan goes smoothly.
