What is a Masseter Botox?
Masseter Botox is Botox injected into the masseter — the large chewing muscle at the back of the jaw. It is used to slim a wide or square jawline, soften an overactive jaw, and relieve TMJ symptoms like clenching, grinding, and jaw tension.
Because the masseter is a big, strong muscle, it takes far more units than a wrinkle treatment — typically 20 to 50 units total across both sides. Jaw slimming is gradual: you will notice tension relief within a week or two, but visible narrowing develops over 6 to 8 weeks as the muscle shrinks with disuse. Results last about 4 to 6 months.
Most providers price masseter Botox per unit, the same rate as regular Botox, so your cost depends mostly on how many units your jaw needs. Ask how your provider prices and roughly how many units they expect before booking.
How much does a Masseter Botox cost in Boston?
Masseter Botox in Boston typically runs $360 to $900 per session because the jaw muscle needs 20 to 50 units. Per-unit providers in Boston charge about $12-$18 per unit, so the total comes down to how strong your masseter is and whether you are treating for slimming, TMJ relief, or both.

What to ask your provider
- How many units do you recommend for each side of my jaw, and why?
- Am I a candidate for slimming, TMJ relief, or both?
- How long until I see the jaw actually narrow — and how long will it last for me?
- What happens to chewing and my smile while the muscle relaxes?
- Do you price per unit, and what is your current rate?
- How many masseter treatments do you perform each month?
Frequently asked questions
How much does masseter Botox cost in Boston?
Masseter Botox in Boston typically costs $360 to $900 per session. The jaw muscle needs 20 to 50 units at roughly $12 to $18 per unit, so a stronger masseter costs more. Ask your provider for an estimated unit count before booking.
How many units do I need for jaw slimming?
Most jaw-slimming treatments use 30 to 50 units split across both sides. TMJ relief alone may need only 20 to 25. Your provider should base the number on how strong and prominent your masseter is, not a flat rate.
How long until masseter Botox slims the jaw?
Tension and clenching relief often start within one to two weeks, but visible slimming develops over 6 to 8 weeks as the muscle shrinks from reduced use. Full effect is usually seen by two to three months.
Does masseter Botox help TMJ and teeth grinding?
Yes — relaxing the masseter reduces clenching and grinding force, which eases jaw tension, soreness, and TMJ-related headaches for many patients. Some treat purely for TMJ with no interest in slimming.
How long does masseter Botox last?
Masseter Botox typically lasts 4 to 6 months — often a bit longer than facial Botox because the muscle takes time to rebuild strength. Repeat sessions can lengthen results as the muscle stays smaller over time.
