How the Treatment Works for Teeth Grinding
Targeted at the muscle, not the teeth, for long-lasting relief that complements your existing dental care.
Without treatment
- •Over-contracted masseter muscle
- •Heavy grinding & clenching force
- •Progressive enamel wear & fractures
- •Recurring jaw pain & headaches
- •Damage to crowns, veneers and fillings
- •Increased risk of TMJ disorders
After treatment
- Masseter activity partially relaxed
- Reduced grinding force on teeth
- Less morning jaw pain & tension headaches
- Better protection for your dental work
- Lower risk of fractures and worn restorations
- Subtle slimming of bulky jaw line over months
Often combined with a night guard. For severe grinders we frequently recommend wearing a custom night guard alongside the injections. They reduce the muscular force; the guard provides a physical barrier between your teeth. The two work very well together, particularly for protecting crowns, veneers and implant restorations.
Benefits of Muscle-Relaxing Injections for Bruxism
A minimally invasive option for patients whose grinding has not been controlled by a night guard alone.
Reduces Grinding Force
The injections partially relax the masseter muscle, which can significantly reduce the force generated during clenching and grinding.
Protects Your Teeth
Lower bite force helps protect natural teeth, fillings, crowns, veneers and implant restorations from continued wear and fracture.
Relieves Jaw & Head Pain
Many patients report reduced morning jaw pain, tension headaches and facial muscle fatigue within 1–2 weeks.
Quick, In-Chair Procedure
The injection appointment itself usually takes around 15 minutes, with no downtime and a normal return to daily activities.
Subtle Jaw Slimming
In patients with enlarged masseter muscles, treatment can gently soften and slim the lower face shape over several months.
Complements a Night Guard
Works alongside a custom night guard for severe bruxism, the injections reduce the force, the guard protects the teeth.
Your Treatment Journey
From first consultation to follow-up review, what to expect.
Consultation & Assessment
Dr Carlos reviews your medical history, symptoms, jaw function and dental wear patterns to confirm bruxism and rule out contraindications.
Treatment Plan & Consent
You receive a personalised plan, written consent, and a clear explanation of dose, expected effects, risks and aftercare.
Injection Appointment (~15 mins)
Small precise injections are placed into the masseter muscles on each side. Discomfort is minimal, most patients describe it as a quick pinch.
Review at 2 Weeks
A follow-up appointment is included to assess your response. Small top-ups can be made if needed to fine-tune the result.
Maintenance Every 3–4 Months
Effects typically last 3–4 months. Repeat sessions help maintain relief and, over time, may reduce the dose required.

Frequently Asked Questions
A prescription muscle-relaxant is placed into the masseter, the powerful muscle that closes your jaw. By partially dampening the nerve signals that drive its contraction, the injections take the force out of clenching and grinding while leaving normal chewing and speech unaffected. The result: less strain on your teeth and relief from jaw and head pain.
