what does masseter botox do

Masseter Botox relaxes the jaw muscle used for chewing, which can reduce teeth grinding, jaw clenching, TMJ-related tension, and can also make the lower face look slimmer over time.

What it does

It works by temporarily blocking nerve signals to the masseter muscle, so the muscle can’t contract as strongly.

Common reasons people get it

• To ease jaw pain or tightness from clenching or grinding.

• To soften a square or bulky jawline.

• To help with facial asymmetry caused by an overactive masseter.

What to expect

Some people notice less tension within days to a week, while the slimmer jawline effect usually shows more gradually over 2 to 6 weeks. Results commonly last about 3 to 6 months.

Important note

It should be done carefully by a qualified injector, because too much or poorly placed treatment can affect chewing, smile balance, or facial movement.
