Teeth Grinding Relief with Masseter Botox®

Botox® injections into the masseter muscle provide dual benefits: alleviating aches and pains caused by grinding or clenching, and softening and narrowing the appearance of a wide face and square jaw.

Fast Facts

Masseter Botox

Injecting small doses of botulinum toxin directly into the masseter muscle weakens it enough to stop involuntary grinding of the teeth and clenching of the jaw. This relaxation reduces wear and tear on the teeth, damage to the temporomandibular joint (TMJ), and headaches. Voluntary movements like chewing and facial expressions are not affected by Botox®.

Additionally, Botox® in the jaw can slim and contour the lower face, making it a popular treatment for those with a more masculine, square-shaped jawline or chubby cheeks.
