Jaw tension, teeth grinding, and facial discomfort are more common than many people realise. Often linked to stress or sleep-related habits, these issues can affect not only your comfort — but also your long-term dental health and facial shape.
At Fluid Medical, we offer a safe, doctor-led treatment using Botulinum toxin to target the masseter muscles — helping to relieve discomfort while subtly refining the jawline.
What Are the Masseter Muscles?
The masseter muscles are the strong, rectangular muscles located on either side of your jaw. They play a key role in chewing, but when overactive, they can contribute to:
* Teeth grinding (bruxism)
* Jaw clenching
* Facial tension and discomfort
* Headaches
* Tooth wear and damage
* A widened or square jawline
Overactivity in these muscles is often driven by stress, habitual clenching, or sleep-related grinding — and without treatment, symptoms can worsen over time.
How Does Masseter Botox Work?
Botulinum toxin is carefully injected into the masseter muscles in small, controlled doses. This temporarily reduces the strength and activity of the muscle.
By relaxing the masseters, the treatment helps to:
* Decrease the force of clenching and grinding
* Relieve jaw tension and discomfort
* Protect teeth from excessive wear
* Gradually reduce muscle bulk
As the muscle becomes less active, it can also soften the appearance of a wide or square jaw — creating a more tapered, balanced facial shape.
The Benefits of Masseter Treatment:
* Slimmer, more contoured jawline
* Reduces clenching and grinding
* Eases jaw discomfort and tension
* Non-surgical and minimally invasive
* Gradual, natural-looking results
This treatment offers both functional relief and aesthetic refinement — making it a popular option for patients seeking a dual benefit approach.
What to Expect
The procedure is quick and performed in-clinic by a qualified doctor. There is minimal discomfort and no required downtime, allowing you to return to your normal routine immediately.
Results typically:
* Begin to appear within 1–2 weeks
* Last approximately 3–4 months
With consistent treatment, the masseter muscles may gradually reduce in size over time, and symptoms of grinding and clenching often become less severe.
