Muscle relaxant inject into the TMJ muscles often eliminate headaches, reduce neck and back pain resulting from teeth grinding and jaw tension

Jaw Muscle Relaxant Injections – Penrith
Muscle relaxant injections may assist in managing concerns related to teeth clenching, jaw tension, and facial muscle overactivity. Two commonly treated muscles are the masseter (at the jawline) and the temporalis (located at the sides of the forehead and above the ears), both of which play a role in chewing and clenching.
When overactive, these muscles may contribute to facial tension or discomfort. Muscle relaxant injections may help soften their activity and support a more relaxed facial profile.
Common Reasons Patients Seek Treatment
Persistent clenching or grinding of the teeth (bruxism)
Muscle tension in the jaw or temples
Discomfort extending to the neck, head, or facial areas
Interest in a softer, more contoured jawline
Treatment Areas: Masseter and Temporalis
Masseter Muscle: Located at the sides of the jaw, this muscle contributes to chewing and can appear prominent in people with strong or square jawlines. Reducing its activity may help slim the face and ease jaw tension.
Temporalis Muscle: Found on the sides of the forehead, this muscle also assists in chewing and clenching. In some cases, treating this area can support overall jaw muscle balance and provide added relief from muscle overactivity.
