Masseter Botox
Masseter Botox is a specialised injectable treatment that targets the powerful chewing muscles at the sides of your face. By administering botulinum toxin into these muscles, the treatment can effectively reduce teeth grinding, alleviate jaw tension, and create a more refined facial contour.
At Bolton Aesthetics Clinic, these treatments are performed by Gail herself—a highly qualified practitioner with extensive credentials, including GRMN, DPSN, BSC (Hons) MSc, and nurse prescriber status—ensuring you receive the highest standard of care with optimal safety and results.
About Masseter Botox
Think of masseter Botox as a therapeutic and aesthetic solution for your jaw area. This remarkable treatment works by temporarily relaxing the masseter muscles—the strong muscles responsible for chewing that connect your cheekbone to your lower jawbone. When these muscles become overactive through habitual clenching or grinding, they can cause physical discomfort and create a square, widened appearance to the lower face.
With Gail’s advanced medical qualifications and specialised understanding of facial anatomy, you can trust that your treatment precisely targets the correct muscle fibres for optimal results. Her approach balances the therapeutic benefits of pain relief and tension reduction with the aesthetic advantages of facial slimming. Whether you’re seeking relief from teeth grinding or jaw pain or simply wish to refine your facial contours, Gail’s medical expertise ensures your treatment is performed with precision, safety, and an artistic eye for balanced, natural-looking results.


How Masseter Botox Works
The Science Behind Muscle Relaxation
The Treatment Process
Your masseter Botox treatment at Bolton Aesthetics Clinic begins with a thorough consultation where Gail evaluates your jaw muscles, facial structure, and specific concerns. The actual procedure is quick and straightforward:
- The treatment area is cleansed thoroughly to reduce infection risk
- Gail identifies the precise injection points by having you clench your teeth to feel the masseter bulge
- Using ultra-fine needles, the botulinum toxin is carefully injected into specific points within the muscle
- Multiple injection points ensure even distribution throughout the muscle for balanced results
The entire procedure typically takes just 10-15 minutes with minimal discomfort
Most clients report only mild discomfort during the injections, describing the sensation as a quick pinch. No downtime is required, allowing you to return to normal activities immediately after treatment.
Results Timeline
Following your masseter Botox treatment, results develop gradually:
- Initial relaxation begins within 3-5 days
- Full muscle relaxation effects typically appear within 10-14 days
- Noticeable facial slimming may take 3-4 weeks as the muscle gradually reduces in size
- Results typically last 4-6 months before the muscle gradually returns to its original state
- With repeated treatments, longer-lasting results often develop as the muscle becomes conditioned

Benefits of Masseter Botox
Therapeutic Benefits
- Teeth Grinding Relief: Reduces bruxism by limiting the masseter’s ability to contract forcefully, protecting teeth from damage
- TMJ Pain Reduction: Alleviates tension in the temporomandibular joint, reducing associated headaches and facial pain
- Jaw Tension Release: Relieves chronic clenching and associated discomfort through targeted muscle relaxation
- Headache Prevention: Reduces tension headaches triggered by jaw clenching and muscle overactivity
- Improved Sleep: Many clients report better sleep quality without nighttime grinding and clenching
Aesthetic Benefits
- Facial Slimming: Creates a more oval or V-shaped facial contour by reducing the width of the lower face
- Jawline Refinement: Softens a square jawline for a more feminine or balanced appearance
- Balanced Facial Proportions: Harmonizes facial features by reducing overly prominent jaw muscles
- Natural-Looking Results: Creates subtle refinement without looking “done” or altering natural expressions
- Non-Surgical Approach: Achieves facial contouring without incisions, anaesthesia, or recovery time
