Masseter Botox in Irvine, CA: Jaw Slimming, TMJ Relief & Bruxism Treatment
If you grind your teeth at night, clench your jaw under stress, or simply feel your face looks wider than you'd like — masseter Botox may be the most impactful 20-minute treatment you've never tried.
The masseter muscle sits at the angle of the jaw. When it's overdeveloped — from grinding, clenching, or genetics — it creates a wide, square jaw. Botox placed precisely into the masseter causes it to partially relax and, over 6–8 weeks, gradually slim.
At Spectrum Skin Clinic in Irvine, Dr. Sabeen Munib performs every masseter Botox treatment personally. Bilateral placement, calibrated dosing, and assessment of your chewing muscle function — this is not a standard cosmetic injection.
Physician-Performed. Bilateral Assessment. Every Time.
Masseter Botox done incorrectly creates asymmetry, weakness in chewing, or an unnatural facial contour. Done correctly — with bilateral assessment, appropriate unit selection, and precise placement — the result is a softer, more oval jaw with no functional compromise.
Dr. Munib palpates your masseter before every treatment, identifies the correct injection zone, and doses bilaterally based on your muscle mass.
Physician assessment. Bilateral precision. Natural jaw contouring.
"I'd been grinding my teeth for years and woke up with jaw pain every morning. After masseter Botox with Dr. Munib, the pain was gone within a week. The jaw slimming was a bonus." — Nicole R.
What Masseter Botox Can Do For You
- Slim a wide or square jaw to a softer, more oval shape
- Relieve bruxism (teeth grinding) — protect your teeth and reduce morning jaw pain
- Reduce TMJ tension and associated headaches
- Decrease the appearance of a heavy or masculine lower face
- Create lower face balance when combined with chin or jawline filler
Jaw Slimming & Contouring
Botox placed into the masseter body reduces the muscle's volume over 6–8 weeks. The jaw transitions from square to oval, and the lower face looks proportionally slimmer. Effect is cumulative with consistent treatment.
Bruxism & TMJ Relief
Masseter Botox significantly reduces the force of nocturnal grinding and daytime clenching. Most patients notice reduced morning jaw soreness within 1–2 weeks. Teeth protection is an important secondary benefit.
Lower Face Rebalancing
A wide jaw can make the chin look recessed and the overall face look bottom-heavy. Masseter slimming, sometimes combined with chin projection filler, rebalances the lower third for more harmonious proportions.
