What are Masseter Relaxing Injections?
The masseter is a powerful chewing muscle located at the side of your jaw. Overuse (from clenching, grinding, or genetics) can cause masseter hypertrophy—making the jaw appear wider or squarer. Masseter Relaxing Injections involve injecting small, controlled doses into this muscle to relax and weaken it slightly. Over time, the muscle diminishes in bulk, giving a softened, more contoured facial appearance.
Beyond aesthetics, Masseter Relaxing Injections are also used to reduce symptoms of bruxism (teeth grinding), jaw clenching, tension headaches, and TMJ discomfort.
Benefits & Applications
• Jaw Slimming / Facial Contouring – Softens a bulky or square jawline by reducing muscle size.
• Bruxism & Jaw Tension Relief – Decreases force of clenching and grinding, reducing wear on teeth, jaw pain, and associated symptoms.
• Reduced Headaches / Facial Pain – Can help alleviate tension headaches originating from overactive jaw muscles.
• Non surgical & Minimal Downtime – Treatment typically takes ~15–30 minutes; patients can usually return to normal activities right after.
• Temporary & Adjustable – Effects are reversible and can be repeated or adjusted over time.
Are Masseter Relaxing Injections for You?
You may be a good candidate if:
• You have broad or square jaw appearance due to strong masseter muscles
• You suffer from bruxism, tooth grinding or jaw clenching
• You experience jaw pain, facial tension or headaches related to muscle overuse
• Your facial bones are proportionate (i.e. not a square jaw due only to bone structure)
• You are in good general health, not pregnant, and have no contraindications to botulinum toxin
However, this treatment may not be suitable for:
• Cases where jaw width is due to bone, not muscle
• Severe TMJ structural disorders needing surgery
• Individuals with neuromuscular diseases, pregnancy, certain medications or health conditions
• Patients seeking permanent change—Masseter Relaxing Injections are temporary and must be repeated
Kelly Ann evaluates all these factors during consultation to ensure safe and effective outcomes.
How long do the effects last?
Typically 3–6 months, depending on dosage, muscle strength, metabolism and patient habits.
Is it painful?
Discomfort is minimal. Many patients feel slight pinpricks during injection. Numbing cream can reduce sensitivity.
Will Masseter Relaxing Injections affect my chewing?
If dosed correctly, it reduces excessive muscle overactivity but does not eliminate chewing function. You should still be able to bite and chew normally.
When will I see results?
Some relief may appear in days; full contour changes often develop after 4–6 weeks.
Can I repeat treatment?
Yes. Many patients have repeat sessions every 4–6 months to maintain results.
Could I get sagging or jowling from this?
When correctly dosed and targeted, this risk is low. Excessive weakening could theoretically lead to changes in lower face support, so precise technique is critical.
