Masseter / Jawline Reduction

Slims the jawline and reduces teeth grinding by relaxing the masseter muscles.

Masseter muscles

What is Masseter / Jawline Reduction?

Masseter treatment targets the large chewing muscle at the angle of the jaw. It has two purposes: cosmetically, it slims a square or heavy lower face and creates a softer, more oval jaw contour; it can also relieve the clenching and grinding that causes jaw pain, tension headaches and worn teeth.

How does Masseter / Jawline Reduction treatment work?

Botulinum toxin is injected into several points within each masseter muscle. With the signal to contract reduced, the muscle is used less forcefully and gradually reduces in bulk, in the same way any muscle atrophies when it is not exercised. Because this is a volume change rather than a surface change, the slimming effect develops slowly over weeks, while the relief from clenching is often felt much sooner.

  • Significant relief from teeth grinding and jaw clenching
  • Reduces tension headaches and morning jaw ache
  • Protects teeth and dental work from grinding damage
