Topic at a Glance

  • TMJ injections may help reduce pain, inflammation, muscle tension, and other symptoms associated with some TMJ disorders.
  • Injections may be considered when conservative treatments have not provided sufficient relief.
  • Depending on the injection type, medication may be delivered into or around the temporomandibular joint or into targeted muscles and trigger points.
  • TMJ injections are generally well tolerated, although temporary discomfort, bruising, swelling, or other side effects may occur.

What Are TMJ Injections?

TMJ injections are minimally invasive procedures used to deliver medication into or around the temporomandibular joint to help reduce pain and inflammation associated with TMJ disorders. The temporomandibular joint connects the lower jaw to the skull and allows the jaw to open, close, and move.

TMJ disorders can cause symptoms such as pain while chewing, talking, and normal daily activities. While TMJ disorders occur, individuals can experience severe headaches as well as difficulty moving their jaw. TMJ injections may help reduce some of these symptoms and improve jaw function.

Injections for TMJ are administered directly into the temporomandibular joint by a healthcare professional. Depending on the type of injection, imaging techniques such as ultrasound or fluoroscopy may be used to help guide accurate placement.

TMJ injection treatments may contain one of the following medications:

  • Botox injections (Botulinum toxin): These may be used to reduce excessive muscle activity and muscle tension in the jaw muscles.
  • Steroid injections: Corticosteroid or steroid injections may be used to help reduce inflammation and pain within or around the joint.

TMJ injections may also be used to treat trigger points in the muscles surrounding the jaw. These painful areas of muscle tension may develop following trauma, repetitive strain, teeth grinding, or jaw clenching, and can contribute to jaw pain and other TMJ symptoms.

A trigger point injection may help relax muscle tension and reduce pain symptoms.

Why Are TMJ Injections Needed?

TMJ injections may be used to reduce TMJ pain, inflammation, and discomfort while improving jaw function for people experiencing symptoms related to temporomandibular joint disorders.

They are typically considered when conservative treatments, such as medication, physical therapy, lifestyle modifications, or oral splints, have not provided sufficient relief. However, the effectiveness of injection therapy can vary from person to person.

TMJ injections may be used in combination with other therapies for managing TMJ disorder symptoms. For example, a steroid injection may provide temporary pain relief, which can make it easier to perform prescribed jaw exercises as part of a broader treatment plan.

Who is a Good Candidate for TMJ Injections?

You may be a good candidate for TMJ injections if you have chronic jaw pain caused by a muscular problem or trigger points. Other factors that may make TMJ injections an appropriate treatment option include the following:

  • Symptoms have not improved despite trying conservative treatments
  • You continue to clench your teeth despite self-care measures and physical therapy
  • Have been evaluated for other possible causes of TMJ, such as nerve involvement

Preparing for a TMJ Injection

Your doctor will provide personalized instructions before your TMJ injections are scheduled. Instructions may include limitations on eating before the procedure or specific guidelines regarding taking existing medication on schedule. Tell your doctor about medications you take, including blood thinners, as well as any allergies, previous reactions to injections, or other health conditions.

During the TMJ Injection Treatment

TMJ injections are a relatively short procedure typically completed in under 30 minutes. The exact steps depend on the type of injection being performed and the area being treated. During the procedure, you can expect to:

  • Be brought into the procedure room
  • Have the injection site cleaned by your doctor or medical team member
  • Receive a local anesthetic if needed to help minimize discomfort.
  • Have the medication injected into or around the TMJ or targeted muscle, depending on the purpose of the treatment.

After the procedure, it is important not to rub the injection site. Side effects from the procedure are typically mild and may include:

Your doctor will provide specific instructions for after the procedure, including follow-up if needed.

Benefits of TMJ Injections

TMJ injections are an office-based treatment that is minimally invasive and allows some patients to return to their normal activities the same day.

TMJ injections may provide temporary or long-lasting relief depending on the patient. Some of the potential benefits of TMJ injections include the following:

  • Reduce symptoms such as pain, inflammation, or muscle spasms in the jaw
  • It may improve jaw movement and function
  • May provide temporary relief that allows patients to participate in other treatments, such as physical therapy or jaw exercises
  • Can be part of a broader treatment plan

Risks and Complications of TMJ Injections

TMJ injections are generally well tolerated, although, like any medical procedure, they carry some risk of side effects or complications. You will usually only experience some temporary discomfort or numbness around the injection site. These side effects can usually be alleviated with pain relievers or ice.

Rare complications of TMJ injections can include the following:

  • Bleeding
  • Bruising
  • Infection
  • Allergic reaction to the anesthetic agent
  • Vascular (vein) injury

When Botox is used, additional side effects may occur. The most common side effects of Botox for TMJ treatment are:

  • Headache
  • Flu-like illness
  • Nausea

What to Expect After TMJ Injections

Side effects from the procedure, including soreness at the injection site, typically decrease after a day or two. Some patients may begin to notice improvement in their pain within 24 to 72 hours, while others may take longer to experience relief. The timeline can vary depending on the type of injection, the underlying cause of the TMJ symptoms, and the individual patient’s response to treatment.
