TMJ trigger point injections can help alleviate symptoms associated with temporomandibular joint (TMJ) disorders, especially when pain and dysfunction are linked to muscle tension or myofascial pain.
Relieving Muscle Tension
Trigger point injections target knots or tight bands in the jaw, face, neck, and head muscles. By injecting a local anesthetic, Toradol , steroid or botulinum toxin (Botox), these muscles relax, reducing tension and discomfort.
2. Reducing Pain
The injections interrupt the pain signals sent from the trigger points to the brain. This provides immediate relief for localized pain and decreases referred pain to the head, neck, or shoulders.
3. Improving Jaw Mobility
By relieving muscle tightness, trigger point injections can help restore normal jaw movement, making it easier to open and close the mouth without discomfort.
4. Addressing Bruxism (Teeth Grinding) For patients who grind or clench their teeth, trigger point injections can help relax overactive muscles like the masseter, preventing further strain on the TMJ.
5. Enhancing Other Therapies
Reduced muscle tension from trigger point injections can improve the effectiveness of other treatments, such as physical therapy, massage, or splint therapy, by creating a less painful and more flexible foundation for healing.
6. Minimizing Headaches and Facial Pain
TMJ disorders often cause tension headaches or facial pain due to referred pain from trigger points. Injections help reduce this referred pain, improving overall comfort.
7. Non-Surgical Alternative
Trigger point injections are a minimally invasive option for patients seeking pain relief without resorting to surgical interventions. They can be an effective part of a broader treatment plan.
Common Substances Used
Local Anesthetic (e.g., Lidocaine, Bupivacaine): Blocks pain signals and provides immediate relief.
Botulinum Toxin (Botox): Reduces muscle overactivity and provides longer-lasting relief (weeks to months).
Corticosteroids: Used in some cases to break up trigger points and reduce inflammation.
