The recovery time for TMJ injections can vary significantly, influenced by health factors, lifestyle, and treatment goals. These injections may be part of a personalised plan to help manage jaw tension, facial pain, and certain TMJ symptoms, though results differ between individuals. They may target specific jaw muscles or the temporomandibular joint to assist in reducing tightness and supporting jaw function, depending on how the body responds.
These injections are often combined with other care options, such as oral splints, jaw exercises, or physical therapy. Recovery experiences differ; some people may notice symptom relief sooner, while others may need more time. Discuss expectations, potential side effects, and follow-up care with a qualified healthcare professional before deciding if this TMJ treatment suits your needs.
Knowing the process and factors that affect recovery can help you prepare for post-treatment. Recovery experiences vary, so seek personalised advice from a qualified dental or medical professional before making treatment decisions.

- Follow-up appointments allow progress checks, treatment adjustments, and discussion of combining therapies such as physical therapy or jaw exercises for improved comfort and function.
What You May Feel in the First 48 Hours After a TMJ Injection
During the first one to two days after TMJ injections, it is common to notice temporary changes near the injection site. These are part of the body’s short-term healing process and are often managed without further treatment. You may experience the following:
- Mild swelling:
Puffiness near the jaw joint may appear within the first 24 hours and typically eases within two to three days. Applying a wrapped cold pack for 10 minutes at a time can help. - Numbness:
Temporary numbness in the facial muscles or around the mouth may occur immediately after the procedure and usually fades within a few hours. - Tightness or muscle tension:
The jaw muscles may feel less flexible for one to two days as the body adjusts to treatment. - Soreness or discomfort:
Mild aching can develop when opening the mouth or chewing during the first 48 hours. Eating soft foods such as mashed potatoes, yoghurt, scrambled eggs, smoothies, pasta, or soup can reduce strain.
These effects generally improve within several days. If symptoms persist beyond a week, or if significant bruising, swelling, or difficulty chewing develops, contact your healthcare provider for assessment.
Common Short-Term Effects and When They May Occur
After TMJ injections, some people may notice temporary changes in the jaw or nearby areas. These effects are often manageable and may improve without additional treatment. The recovery time for TMJ injections can vary, so short-term effects may go away at different rates for each person. In the first few days, you may notice one or more of the following temporary effects:
- Stiffness in the jaw muscles:
This effect can occur within the first 24 hours and may last for two to three days. Gentle jaw movement and avoiding hard foods, such as nuts, raw carrots, or crusty bread, during this period can help maintain comfort. - Tenderness at the injection site:
This feeling may appear within the first day and typically eases within three to five days. Applying a wrapped cold pack for 10 minutes at a time can help reduce sensitivity. - Mild bruising:
This can develop around the injection site within 24–48 hours and often fades within a week. - Temporary swelling:
This may appear near the jaw joint during the first two days and usually improves within three days. - Soreness when chewing:
This can occur during the first 48 hours. Choosing soft foods such as oatmeal, cottage cheese, ripe bananas, poached fish, or blended vegetable soup can help reduce strain while still supporting nutrition.
When Might Symptom Relief Begin?
The recovery time for TMJ injections varies for each person. Some notice changes within days, while others need several weeks. Relief timing depends on the injected substance, the severity of the condition, and overall health conditions.
Relief patterns also differ by injection type. The sections below outline common timeframes and influencing factors.
How Quickly Botulinum Toxin Injections May Work
Botulinum toxin injections may begin to reduce muscle activity within three to seven days, though this can vary. Many people notice maximum effect after one to two weeks. Response time can depend on muscle tone, injection placement, and the amount administered.
What to Expect With Corticosteroid Injections
Corticosteroid injections may ease inflammation within one to three days, although some people take longer to notice changes. The speed of improvement often relates to inflammation levels and general health.
Relief Timeline for Hyaluronic Acid Injections
Hyaluronic acid injections may take longer to relieve symptoms. These injections improve joint lubrication, with effects developing gradually over several weeks. This approach is often selected for joint-related concerns such as reduced jaw movement or stiffness.
Why Some Patients May Experience Delayed Relief
People with chronic or complex TMJ disorders may respond more slowly to treatment. Progress may be gradual. If no improvement occurs after the expected timeframe, it is important to see a healthcare provider for reassessment.
Factors That Can Influence Recovery and Results
The speed of recovery and the degree of symptom relief after TMJ injections can vary for each person. Multiple elements may affect how the body responds, how long the benefits last, and how comfortable recovery feels. Knowing these factors can help set realistic expectations and support discussions with your healthcare provider.
Severity and Duration of TMJ Symptoms
People with mild TMJ symptoms may notice changes sooner than those with long-term or severe discomfort. If the jaw joint or surrounding facial muscles have been strained for months, tissues may take longer to respond. Relief may appear gradually as muscle tension and inflammation reduce.
Type and Dose of Injection Used
The type and amount of substance injected, whether botulinum toxin, corticosteroids, or hyaluronic acid, may influence the degree of pain relief and its duration. Each formulation works differently, targeting muscle activity, inflammation, or joint lubrication. Some focus on easing muscle tension in the jaw muscles, while others aim to improve jaw movement or reduce swelling in the temporomandibular joint. The dosage may also influence results, with adjustments based on the person’s TMJ symptoms and treatment goals.
Response to Previous Treatments
A person’s history with other TMJ treatments can provide insight into how they might respond now. If oral splints or jaw exercises have eased facial pain in the past, injections may offer similar benefits. If earlier treatments produced limited improvement, injections may still help, but could require more time or be combined with physical therapy.
Overall Health Conditions
General health can affect recovery. Conditions such as bruxism (teeth grinding), arthritis, or high stress levels may continue to strain the jaw joint after treatment. Managing these factors, through stress management, limiting gum chewing, or using muscle relaxants when appropriate, may help support longer-lasting benefits.
Clinical Judgement and Technique
A healthcare professional’s choice of injection site and method may influence comfort and results. Targeting the specific muscles or areas within the temporomandibular joint may help the medication reach the intended location. Technique can also affect comfort during the outpatient procedure and the extent of any muscle relaxation or pain relief.
How Long Do the Effects Last?
The duration of benefits from TMJ injections can vary depending on the type of injection and individual response.
Botulinum toxin effects may last about three to six months, with a gradual return of muscle activity over time. Corticosteroid injections may provide relief for roughly four to eight weeks, though some people experience benefits for up to three months. Hyaluronic acid injections may offer benefits for around three to six months, particularly when aimed at supporting joint lubrication and jaw movement.
When to Follow Up With Your Healthcare Provider
Attending scheduled follow-up appointments helps monitor progress and adapt your TMJ treatment as needed. Seek advice sooner if facial pain, jaw stiffness, or other TMJ symptoms persist or worsen.
Ongoing evaluation allows for adjustments that support safe and effective care, whether that means changing the injection type, adjusting the dose, or combining with other approaches such as physical therapy or jaw exercises.
Final Thoughts
The recovery time for TMJ injections can vary from person to person. Some people may notice early sensations such as mild swelling or jaw tightness, while others may focus more on gradual improvements in jaw function and symptom relief. Timelines for benefits can range from a few days to several weeks, depending on the type of injection, individual health, and other influencing factors.
