Trigger Point Injections

Treatment Options

How Do Trigger Point Injections Work for Orofacial Pain Relief?

Trigger point injections target specific areas of the jaw, head, and neck musculature to alleviate chronic headaches and TMJ pain. These injections are relatively comfortable and performed in-office. During the procedure, an anaesthetic such as lidocaine or mepivacaine is injected into the trigger points. The anaesthetic numbs the site, reducing the perception of referred pain for a few hours. Additionally, the mechanical disruption of the knot with a needle modifies the transmission of pain fibres, providing therapeutic pain relief that can last from days to months.

Why Might I Need a Trigger Point Injection?

You may need a trigger point injection if you experience chronic TMJ headaches, neck pain, or muscle tension. Trigger point injections offer relief by mechanically prodding the muscle and introducing a local anaesthetic to alleviate pain and reduce muscle tension and spasm. These injections are particularly beneficial for some patients with TMJ pain caused by teeth clenching and grinding, addressing the underlying issues contributing to muscle discomfort.

How Can a Trigger Point Injection Help Me?

Trigger point injections for TMJ pain can significantly reduce discomfort and improve muscle function for many patients. The mechanical needling process helps diminish muscle tension and spasm, while the local anaesthetic interrupts pain-irritated nerves, providing short-term pain relief and reducing soreness. Most patients experience a welcome lessening of pain within a few days after the injections. Multiple injection sessions spaced three to six weeks apart may be necessary for optimal results. Throughout the treatment process, efforts are made to identify and mitigate risk factors such as teeth clenching and grinding, promoting long-term relief and improved muscle health. Unlike surgical interventions, trigger point injections are minimally invasive, offering fewer risks and a quicker recovery time. Patients can resume their daily activities with minimal disruption after treatment.
