MRI scans
MRI TMJ
A scan of the temporomandibular (jaw) joints that shows the position and movement of the joint disc.
What to expect
- Preparation: Usually none - eat, drink and take medication as normal unless told otherwise. You will complete a safety questionnaire covering implants and previous surgery, and remove all metal items before the scan.
- During the test: You lie on a motorised couch that moves into the scanner. The machine is noisy, you wear ear protection, and you need to keep as still as possible. Most MRI examinations take 20-45 minutes.
- Results: A consultant radiologist reports the scan, typically within 24-72 hours of your appointment.
- Who follows up: The report goes to your referring GP or specialist, who explains the findings and arranges any follow-up.
- Cost: an indicative cost varies by provider.
About this test
A scan of the temporomandibular (jaw) joints that shows the position and movement of the joint disc. It is usually recommended for persistent jaw pain, clicking or locking that has not settled with conservative care.
How to access it privately
You can arrange a private MRI either with a referral from your GP or specialist or, for many scans, by self-referring as a self-pay patient with a short pre-scan questionnaire. Routine NHS diagnostic waits are often long - frequently measured in months - whereas private slots are typically available within days to around two weeks. Costs vary by provider and should be confirmed with the provider before booking.
Frequently asked
Common questions about MRI TMJ.
Quick, plain-English answers to what people ask us most.
-
What is MRI TMJ?
MRI TMJ is a diagnostic test used to look at a specific part of the body or how it is functioning, helping doctors reach a clear diagnosis. It is usually requested when symptoms, an examination finding, or an earlier test result needs further investigation. Your doctor can explain exactly why it has been suggested in your case.
-
Why would a doctor order MRI TMJ?
Doctors typically request this test to confirm or rule out a suspected condition, investigate unexplained symptoms, or monitor something that has already been diagnosed. It gives more detailed information than a standard examination alone can provide. The result helps guide what treatment or further investigation, if any, is needed.
-
Do I need to prepare for MRI TMJ?
Preparation depends on the exact scan; some require fasting, a full bladder, or pausing certain medications, while others need no preparation at all. You will usually be sent clear instructions when the appointment is booked, and any implants, allergies, or previous surgery should be flagged in advance. If you are unsure what applies to you, check with the booking team beforehand.
-
What happens during MRI TMJ?
You will usually be positioned comfortably while the scanner or ultrasound probe captures images of the relevant area; the appointment itself is typically straightforward and does not usually require an overnight stay. A radiographer or sonographer guides you through each step, and most appointments are completed within an hour. You can normally go home and resume your usual activities shortly afterwards, unless told otherwise.
-
Does MRI TMJ hurt or carry risks?
Most imaging tests are painless and non-invasive, though scans with contrast dye or those requiring an injection may involve brief discomfort. Serious complications are uncommon, and the team will explain any relevant risks, such as those linked to contrast agents or radiation exposure, before you go ahead. Let staff know about any allergies or kidney problems beforehand.
-
How long do results take?
Results are usually reported by a specialist within a few days, though this can vary depending on the complexity of the test and whether further analysis is needed. You will normally be told when and how to expect your results at the time of booking. Urgent findings are typically flagged and communicated more quickly.
-
What do abnormal results mean, and what happens next?
An abnormal result does not automatically mean something serious - it simply indicates that further assessment may be needed. Your doctor will review the findings in the context of your symptoms, history, and any other test results before recommending next steps, which might include further investigation, referral to a specialist, or reassurance that no action is needed. Always discuss your specific results with a doctor rather than interpreting them alone.
-
Is MRI TMJ available privately, or should I wait for the NHS?
MRI TMJ can usually be arranged privately, often within days, with results reviewed by a specialist rather than waiting for routine NHS scheduling, which can take considerably longer depending on local demand. Cost varies by provider, and many private providers accept both self-referral and GP or specialist referral. Your GP can also advise on the appropriate NHS pathway if you would prefer to wait.
-
Is MRI TMJ accurate and reliable?
This is a well-established test used routinely in clinical practice, and when performed and interpreted by an experienced specialist it is generally considered reliable. As with any test, results are always interpreted alongside your symptoms and medical history rather than in isolation. Occasionally a test may need to be repeated or supplemented with further investigation for a fully clear picture.
-
How do I book MRI TMJ privately, and how quickly can I be seen?
You can typically book privately with or without a GP referral, and appointments are often available within a matter of days. A specialist reviews and reports the results, with a clear explanation of what they mean and any recommended next steps.
