Temporomandibular Joint (TMJ) Injection

If you suffer from jaw pain, clicking, locking, or difficulty opening your mouth, a Temporomandibular Joint (TMJ) injection may be a non-surgical option to relieve pain and improve jaw function. This guide explains what a TMJ injection is, who it’s for, its benefits, risks, how to prepare, and frequently asked questions.

What Is a Temporomandibular Joint (TMJ) Injection?

A TMJ injection is a minimally invasive procedure in which a corticosteroid, anesthetic, or other therapeutic agent is injected into the temporomandibular joint, located at the junction of your jawbone and skull, just in front of the ear.

TMJ injections are used to treat conditions such as:

Temporomandibular joint dysfunction (TMD)
Jaw arthritis
Joint inflammation
Internal derangement
Persistent jaw pain that hasn’t responded to conservative treatments

The goal of the injection is to reduce inflammation, relieve pain, and restore jaw movement.

Is a Temporomandibular Joint (TMJ) Injection Right for Me?

You might be a candidate for a TMJ injection if:

You have chronic jaw pain, tightness, or popping sounds
You’ve been diagnosed with TMD, arthritis, or jaw joint inflammation
Oral appliances, anti-inflammatories, or physical therapy have not provided relief
You want to avoid or delay more invasive treatments or surgery
Your jaw pain is affecting eating, speaking, or sleep

Benefits of Temporomandibular Joint (TMJ) Injections

Key benefits of TMJ injections include:

Targeted pain relief at the joint
Reduction in inflammation and swelling
Improved jaw mobility
Outpatient procedure with minimal downtime
May help avoid surgery.
Can be diagnostic, confirming the TMJ as the source of symptoms

Risks of Temporomandibular Joint (TMJ) Injections

While safe for most people, possible risks include:

Mild pain or swelling at the injection site
Facial bruising
Infection (very rare with proper sterile technique)
Temporary facial numbness or weakness (if anesthetic affects nearby nerves)
Allergic reaction to injected medications
Joint stiffness or flare-up for 1–2 days
Tissue thinning if steroids are used frequently

How to Prepare for a Temporomandibular Joint (TMJ) Injection

Here’s how to prepare:

Inform your provider of any allergies, medications, or recent infections
Let them know if you are on blood thinners
You do not need to fast or change medications unless instructed
Wear comfortable clothing and avoid applying makeup near the jaw area
No sedation is typically used; you may drive yourself to and from the appointment.

How Is a Temporomandibular Joint (TMJ) Injection Performed?

A TMJ injection is quick and typically done in the clinic:

Positioning: You'll lie down or recline slightly.
Skin cleaning: The skin over the TMJ is cleaned thoroughly.
Numbing: A local anesthetic may be used.
Injection: A small needle delivers medication into the TMJ. Ultrasound or fluoroscopic guidance may be used for precision.
Bandage: A small adhesive bandage is applied.

The procedure usually takes 10–15 minutes.

Post-Procedure Care and Restrictions

After the injection:

You may experience mild soreness or stiffness for 1–2 days
Apply ice to the area if needed
Avoid chewing tough or hard foods for 24–48 hours
Return to normal activities as tolerated
Avoid jaw clenching or excessive talking for a day or two
Monitor for any unusual symptoms such as redness, heat, or persistent numbness

How Long Will It Last? Will I Need More?

Relief may begin within a few days, with effects lasting weeks to months
Some patients need repeat injections, especially in cases of chronic TMJ inflammation
Injections are typically spaced out, often no more than 3–4 per year per joint

Frequently Asked Questions (FAQs) About Temporomandibular Joint (TMJ) Injections

Q: Will the injection hurt?
A: Most patients tolerate the injection well. A numbing agent may be used to reduce discomfort.

Q: Can I eat after the procedure?
A: Yes, but stick to soft foods for the first day or two.

Q: Can this cure my TMJ disorder?
