Masseter Treatment (Jaw Slimming)

A slimmer face. A softer jawline. Relief from teeth grinding. One injection.

The masseter is the powerful chewing muscle on either side of the jaw. When overly developed — due to habitual teeth grinding (bruxism), jaw clenching, or genetics — it creates a wide, square lower face. Botulinum toxin injected into the masseter temporarily weakens and shrinks the muscle, slimming the lower face and creating a softer, more oval or V-shaped facial contour.

Benefit Details Facial Slimming Reduces the width of the lower face — results visible at 4-6 weeks as muscle volume reduces Bruxism Relief Significantly reduces grinding force — protecting teeth and reducing headaches and jaw pain TMJ Symptom Relief Relieves temporomandibular joint pain and clicking caused by excessive masseter tension Asymmetry Correction Different doses on each side correct natural or acquired jaw asymmetry Treatment Time 15-20 minutes Onset Slimming effect visible at 4-6 weeks (muscle atrophy takes time) Duration 4-6 months; longer with repeated treatment Downtime None — mild jaw tenderness for 24-48 hours only

Frequently Asked Questions

Will I lose chewing ability?

No. The masseter is significantly stronger than needed for normal chewing — reducing its volume does not impair eating in any meaningful way. Patients occasionally notice slightly reduced bite force on very hard foods in the first few weeks, which fully normalises.

Can men have masseter treatment? Yes — typically for bruxism relief and TMJ symptom management rather than facial slimming. The treatment and dose are identical; only the aesthetic goal differs. Slim your jaw, ease your grind — drbhavyaplasticsurgery.com
