If you’ve been dealing with jaw pain, stiffness, or clicking when you speak or chew, it’s natural to explore treatment options for relief. One question that often comes up is, are TMJ injections painful?
This concern is completely understandable, especially for those already experiencing facial pain, chronic tension, or sensitivity in the jaw area. The idea of injections near the jaw joint can cause anxiety, even if the procedure is brief and commonly performed in dental settings.
Temporomandibular joint disorders (TMD) affect the joints and jaw muscles responsible for chewing, speaking, and overall jaw function. These issues can lead to painful clicking, limited movement, and ongoing muscle tension around the temporomandibular joint.
When self-care techniques or physical therapy haven’t provided enough symptom relief, TMJ injection treatments may be recommended as part of your broader care plan. These may include botulinum toxin (Botox), corticosteroids, or other medications, depending on your symptoms.
In this article, we’ll walk you through the full process—what to expect, how discomfort is managed, and what the procedure actually involves. Our goal is to give you realistic, helpful information so you can feel more confident when exploring your treatment options.

Understanding TMJ Disorders and Injection Treatments
The temporomandibular joint (TMJ) connects your lower jawbone to your skull. It plays a key role in speaking, chewing, and everyday jaw movement.
When this joint or surrounding muscles become inflamed, irritated, or overworked, it can lead to temporomandibular joint disorder (TMD). This condition affects many adults.
Common symptoms of TMJ disorders include:
- You may hear or feel clicking or popping when chewing or yawning.
- Muscle spasms can occur in the jaw, neck, or shoulders.
- Some people feel tightness or pressure in their jaw joints.
- Facial pain often develops near the temples or around the ears.
- Jaw movement may become limited, uneven, or uncomfortable.
TMD can result from teeth grinding, clenching, jaw injury, or chronic muscle tension. It may also relate to arthritis or joint wear over time.
When nonsurgical treatment options like mouth guards, oral splints, or physical therapy have not been effective, your provider might consider TMJ injection treatments.
There are several types of injections, each used for different symptoms:
- Steroid injections may help reduce inflammation inside the joint capsule.
- Botox injections can relax overactive facial muscles, which may relieve chronic jaw pain caused by grinding or clenching.
- Trigger point injections use a local anaesthetic or muscle relaxant to target painful taut bands within the muscles.
- Intra-articular injections are placed directly into the joint to relieve pain, improve mobility, and support muscle relaxation.
The type of injection used will depend on the cause of your symptoms, the severity, and your response to previous treatments. Your dental professional will recommend an appropriate approach after assessing your individual needs.
How Painful Are TMJ Injections?
If you’re considering this treatment, a common question patients ask is, “Are TMJ injections painful?
It’s a common concern. While most patients experience only mild discomfort, pain levels can vary depending on several individual and treatment-related factors.
Some people describe the sensation as similar to a quick flu shot or a mild sting like a local anaesthetic injection you might receive at the dentist. Others feel slight pressure or aching around the injection site, especially if the area is already inflamed or tender.
Several factors can affect your level of discomfort during TMJ treatment, including:
- The type of injection being administered plays a role. For example, intra-articular injections that go directly into the TM joint may feel different from trigger point injections placed into tight chewing muscles.
- The injection site itself also matters. Areas with more nerve endings or existing muscle tension may feel more sensitive during the procedure.
- Your personal pain threshold influences how you perceive the injection. Everyone responds differently—what feels like a mild pinch to one person may feel sharper to someone else.
- Anxiety or past medical experiences can increase pain sensitivity. Feeling nervous about the procedure can cause your body to tense up, which may heighten discomfort.
- The presence of chronic conditions, such as myofascial pain or TM joint pain, can make the area more reactive to touch, pressure, or needle insertion.
Although the experience can vary, here’s what many patients report during and after TMJ injections:
- You may feel a quick pinch followed by a burning or stinging sensation as the medication is injected into the tissue.
- Injections targeting facial muscles or trigger points may produce a dull ache that lasts a few moments. This often settles quickly.
- Some patients feel mild soreness, swelling, or bruising at the injection site, especially if inflammation or scar tissue is present.
- You may also notice a temporary feeling of tightness or fullness in the area as the injected material begins to work.
- After the injection, minor side effects like redness, tenderness, or numbness may occur but typically improve within a few days.
- These sensations are considered part of the normal response to the injection and are usually mild. The procedure itself is brief and often completed in a single outpatient clinic visit.
If pain persists, worsens, or feels unusual after the injection, it’s important to speak with your dentist or qualified healthcare professional. They can assess the situation and determine whether additional care or a different treatment option is appropriate.
Pain Management During TMJ Injections
Pain management is an important part of any TMJ injection procedure. While some temporary discomfort may occur, clinics use several techniques to keep patients as comfortable as possible.
The process usually begins with preparation. A topical anaesthetic gel is often applied to numb the surface of the skin or inner cheek. This helps reduce the sting when the needle is inserted.
In many cases, a local anaesthetic is used. It numbs the deeper tissues around the injection site. This helps block pain signals during the procedure.
Techniques used to manage discomfort during TMJ injections:
- A topical numbing agent can be applied to the skin or gums. This reduces surface sensitivity before the injection begins.
- A local anaesthetic may be injected to numb the area more deeply. This helps minimise pain during treatment.
- Most clinics use slow, controlled injection techniques. This helps limit tissue irritation and lowers the risk of bruising or additional soreness.
- During the procedure, the jaw may be gently supported. This helps relax the facial muscles and keeps the area stable for accurate treatment.
What patients might still feel:
- Even with anaesthetic, you may feel a brief pinch as the needle is inserted.
- Some patients notice pressure during the injection. This is more common in areas of muscle tightness or around the TM joint.
- A sense of fullness or warmth might be felt after the medication is delivered. This depends on the substance used, such as botulinum toxin or triamcinolone acetonide.
- It’s also normal to feel mild swelling, tenderness, or soreness at the injection site after the procedure. These effects are temporary.
Pre-injection tips to reduce anxiety and discomfort:
- During your consultation, ask questions and share concerns. Knowing what to expect can help you feel more prepared.
- Try relaxation techniques before your appointment. Slow breathing or gentle stretching may ease stress and reduce muscle tension.
- Follow all instructions provided before your procedure. This may include advice about food, fluids, or adjusting prescription medications.
- Wear comfortable clothing for your visit. Avoid tight collars or scarves, especially around the neck and jaw area.
Pain levels vary from person to person. Stress, past experiences, and the presence of chronic pain or inflammation can influence them.
After treatment, you may be advised to use ice packs or other pain relief options. These help reduce TMJ pain, soreness, and any residual muscle tension.
These comfort measures are often part of a broader approach to managing TMJ disorders. They may be used alongside oral appliances, physical therapy, or procedures like TMJ arthroscopy.
The TMJ Injection Procedure: Step by Step
Understanding what happens during a TMJ injection can help reduce uncertainty and make the experience feel more manageable. Below is a step-by-step overview of how the procedure is commonly performed in clinical settings.
Before Your Appointment
- Fasting is usually not required. However, avoiding heavy meals may help prevent stomach discomfort.
- Wear comfortable clothes. A loose necklinis helpful, especially if the injection site is near your jaw, neck, or face.
- Bring a current list of any prescription medie cations.
- Inform your practitioner about any allergies or medical conditions. This helps minimise the chance of complications.
- Most people can drive themselves home. If a stronger anaesthetic or sedation is used, you may be asked to organise someone to accompany you.
Arrival and Preparation
- You may be asked to complete a short health form or update your medical history.
- Your provider will review your symptoms, such as difficulty opening, neck pain, or other TMJ dysfunction, and confirm if the injection remains the appropriate treatment.
- The injection site will be cleaned with an antiseptic solution to reduce the risk of infection.
- A topical anaesthetic might be applied to the skin or inner cheek to numb the outer surface.
- In most cases, a local anaesthetic will then be injected to numb the deeper tissues. This helps reduce discomfort during the procedure.
During the Injection
- You’ll be seated in a reclined chair or on a treatment bed. Your head will be gently supported.
- The provider will locate the temporomandibular joint (TMJ) or target muscle, sometimes using touch or ultrasound guidance.
- A fine needle is inserted into the joint or muscle. This could involve intra-articular, trigger point, or botulinum toxin injections, depending on the condition being addressed.
- You may feel a brief pinch, some pressure, or a short-lasting ache.
- The medication is administered slowly to help reduce irritation and support healthy blood flow.
- The full procedure usually takes 15 to 30 minutes, depending on how many injections are administered and the treatment type.
Immediately After the Injection
- Light pressure or a cold compress may be applied if swelling develops at the injection site.
- You’ll be observed for a short period to watch for any immediate reactions.
- Most people can leave shortly after the procedure unless further monitoring is needed.
- Mild soreness, stiffness, or tenderness is common. This can be eased with ice packs, rest, or over-the-counter pain relief.
- You may be advised to avoid chewing hard foods, intense jaw movement, or sleeping on the injection side for a short time.
TMJ injections are often brief and relatively low-risk. When carried out by a trained healthcare professional, the procedure is generally considered safe and well-tolerated.
Knowing what to expect during each step can help you feel more at ease. If you have questions, you’re encouraged to speak with your provider before your visit.
Recovery and Post-Injection Discomfort
After TMJ injections, it’s common to experience mild side effects as your body adjusts. These usually settle within a few days.
What You May Notice
- You may feel soreness or tightness near the area where the injection was given, especially when speaking or chewing.
- Swelling can occur, along with mild jaw discomfort or stiffness.
- Some people feel tired or notice low-grade discomfort in the jaw muscles.
- If trigger point injections are used, the surrounding muscles might feel achy or stiff as they respond.
- These sensations usually improve within several days, though in some cases, they can linger for up to two weeks.
When to Follow Up
Contact your provider if:
- Discomfort worsens or does not begin to settle after a few days.
- Swelling becomes more pronounced or is accompanied by redness or warmth.
- You notice signs of infection, such as discharge or fever.
- Jaw movement becomes more limited or feels significantly more difficult than before the injection.
Early communication helps clarify what’s normal and when further care may be helpful.
At-Home Care Tips
- A cold compress can be applied for short periods to reduce swelling and support comfort.
- If your provider has advised it, a general non-prescription pain relief may assist with short-term soreness.
- It’s helpful to avoid hard or chewy foods for a few days to ease pressure on the jaw.
- Sleeping on your back or opposite the injection side can help reduce direct pressure during rest.
- Warm compresses or light jaw movement exercises may be suggested a day or two later, depending on your provider’s advice.
- Posture awareness and avoiding habits like clenching or grinding can reduce tension and support a more comfortable recovery.
- Any personalised instructions, such as jaw exercises or the use of splints, should be followed to support your progress.
TMJ injections are commonly used in dental settings to support jaw comfort and movement. While recovery varies, most people return to their daily routines shortly after the procedure. If something feels unusual or concerning, a quick conversation with your provider can offer reassurance or guidance.
Benefits vs. Discomfort: Is It Worth It?
As with any medical intervention, TMJ injections have both potential benefits and limitations. Understanding these aspects can support informed decision-making in collaboration with your dental professional.
Potential Benefits of TMJ Injections
- Pain relief:
TMJ injections may help reduce jaw discomfort caused by inflammation or muscle tension. - Improved joint function:
Some patients report enhanced jaw mobility and less stiffness. - Minimally invasive:
Injections may delay or reduce the need for surgical intervention in appropriate cases. - Adjunctive use:
Can complement other therapies such as bite splints, physiotherapy, or lifestyle modifications.
Evidence-Based Outcomes
- Corticosteroids
Corticosteroid injections have been shown to reduce inflammation and improve joint function in patients with certain TMJ disorders. These benefits are especially observed when treatment is administered during the early or moderate stages of the condition [Al-Moraissi et al., 2020. PMID: 31711937]. - Hyaluronic Acid (HA)
Hyaluronic acid injections may support joint lubrication and enhance mobility. Evidence suggests multiple sessions could lead to better long-term outcomes compared to a single injection. - Botulinum Toxin (Botox)
Botulinum toxin injections may help reduce pain associated with muscle overuse or clenching in select TMD patients. However, current evidence is mixed. Its use remains investigational for TMJ management.
Discomfort & Considerations
TMJ injections are generally well tolerated; however, they may cause temporary side effects such as the following:
- You may experience mild soreness or swelling at the injection site following the procedure.
- A feeling of jaw stiffness or fatigue may develop. This usually lasts from a few hours to a few days.
- In rare cases, patients may notice localised bruising or joint discomfort after treatment.
These effects are usually short-lived. They can often be managed with rest, gentle jaw exercises, and over-the-counter pain relief—if recommended by your healthcare provider.
Is It Right for You?
The suitability of TMJ injections depends on several key factors, including the following:
- Your symptoms’ severity and the underlying cause of your temporomandibular condition will play a critical role in determining whether injections are appropriate.
- Your response to prior conservative treatments, such as physiotherapy, occlusal splints, or medications, may influence whether more targeted interventions are necessary.
- Your long-term goals, such as achieving sustained pain relief, improving jaw function, or avoiding surgical procedures, should be considered when exploring injection therapy.
Results from injection therapy can vary from person to person. Factors such as your overall health, diagnosis, and lifestyle may influence how effective the treatment is for you. That’s why it’s important to speak with a dentist experienced in TMJ management to explore the most appropriate options for your needs.
