Cortisone Injection for TMJ: What to Know First
Edited by Merve Aydin, Health Content Editor · About 5 min read · General information, not medical advice
Quick answer
A cortisone injection for TMJ is a corticosteroid placed into or around the jaw joint to reduce inflammation. Mayo Clinic lists it among options when self-care is not enough, but a rapid evidence review in American Family Physician found no clear advantage over saline flushing and flagged potential cartilage damage, so it is not recommended as routine care. NIDCR advises asking about simpler treatments first. It is a decision to make with a clinician who can explain the trade-offs, not a quick fix.
What a cortisone injection for TMJ is
Cortisone is a corticosteroid, a drug that damps inflammation. In the jaw it is injected into the joint space or the tissue just outside it. The goal is to reduce pain and swelling from an inflamed joint lining or arthritis.
It is not the same as:
- Arthrocentesis, which flushes the joint with saline
- Hyaluronic acid, a lubricant injected into the joint
- Botox, which weakens muscles rather than treating the joint
- Trigger point injections, which target muscle bands
Patients often use "cortisone shot" for any jaw injection. Ask exactly what is being injected and where.
Who offers it and how it is done
Joint injections are usually performed by oral and maxillofacial surgeons, some dentists with orofacial pain training, and physicians who treat joint disease. The procedure is brief.
- The clinician examines the jaw, checks opening, and reviews imaging if available.
- The skin is cleaned and numbed.
- A needle is guided into the joint space, sometimes with imaging guidance.
- A small volume of steroid, often mixed with local anesthetic, is injected.
- You are observed briefly, then sent home with aftercare instructions.
AAOMS describes joint surgery as a spectrum, with arthrocentesis and arthroscopy before open procedures. A steroid injection sits on the conservative end, but it is still an invasive step that follows a diagnosis.
What the evidence says
The evidence is mixed, and the disagreement is worth understanding.
The case for: corticosteroids reduce inflammation, and some trials show short-term pain relief. Mayo Clinic lists injections among treatment options for TMD. Clinicians use them for acute inflammatory flares and arthritis.
The case against: a 2023 rapid evidence review in American Family Physician concluded that intra-articular corticosteroids were no better than saline flushing for pain or jaw motion and were not recommended because of potential damage to articular cartilage. A network meta-analysis cited in that review also raised concern about methylprednisolone.
The bottom line: short-term relief is possible, but the benefit is not clearly superior to simpler flushing, and repeated steroid exposure may harm the joint surface. That makes it a selective option, not a first-line treatment.
What to try first
NIDCR recommends conservative, reversible care before procedures. That means:
- Soft foods and jaw rest
- Heat or cold
- Gentle exercises and physical therapy
- Over-the-counter NSAIDs for short periods, if safe for you
- A splint trial for clenching-related pain
- Addressing sleep and stress
If pain persists despite these steps, imaging and an orofacial pain exam can determine whether the joint itself is inflamed, degenerated, or displaced. That diagnosis decides whether an injection is reasonable. See TMJ treatment options for the wider ladder.
Risks and limits
- Cartilage damage. The main concern with repeated steroid injections.
- Infection. Rare but serious; sterile technique matters.
- Bleeding and bruising.
- A post-injection flare of pain for a day or two.
- Facial flushing or a temporary rise in blood sugar.
- Skin thinning at the injection site.
- Nerve irritation if the needle passes near a sensory branch.
Repeated injections are generally avoided. If the first does not help, repeating the same approach is unlikely to change the outcome. A second opinion is reasonable before agreeing to a series.
Questions to ask before agreeing
- What is the diagnosis, and what does the imaging show?
- Is the injection into the joint or the muscle?
- What would saline flushing or physical therapy offer instead?
- How many injections have you performed, and what complications have you seen?
- What is the plan if this does not work?
- What are the risks for my specific health conditions, including diabetes?
- Will this be billed as medical or dental, and what will I pay?
A clinician who welcomes these questions is a better partner than one who promises relief.
A cortisone injection is one option among several, and it is not a substitute for a diagnosis. Read cortisone shot for TMJ for the procedure overview, TMJ arthrocentesis for the flushing alternative, and TMJ trigger point injections if the pain is muscular.

Frequently Asked Questions
Can you get a cortisone shot for TMJ?
Yes, it is offered by some oral surgeons and orofacial pain clinicians. It is not routine first-line care, and evidence does not show a clear advantage over saline flushing.
Does a cortisone shot help TMJ pain?
Some people get short-term relief, especially during an inflammatory flare. Trials have not shown a consistent advantage over simpler treatments, and benefit may fade.
Is a cortisone shot safe for the jaw joint?
It carries risks, including infection, bleeding, and potential cartilage damage with repeated use. A single carefully chosen injection may be reasonable; a series is harder to justify.
How long does a cortisone shot last?
Relief, when it occurs, often lasts weeks. Response varies, and the evidence does not support a predictable long-term effect.
What is the difference between a cortisone shot and arthrocentesis?
Arthrocentesis flushes the joint with saline, while a cortisone shot delivers steroid. Some studies find similar pain relief, and flushing avoids steroid exposure to cartilage.
Will insurance cover a TMJ cortisone injection?
Coverage varies by plan and billing category. Ask whether it is medical or dental, whether prior authorization is required, and what your out-of-pocket cost will be.
