Masseter Muscle Relaxants

The masseter muscles are powerful jaw muscles located on either side of the face. While essential for chewing, overactive masseters can create a wide or square jawline, contribute to clenching and grinding (bruxism), cause jaw discomfort, and even lead to tension headaches.

At Boutique Dental Bondi, we use Dysport® — a trusted neuromodulator — to gently relax the masseter muscles. This treatment offers two main benefits:

  • Jawline slimming: Reduces muscle bulk to create a softer, more refined lower face.

  • Relief from clenching and grinding: Helps ease tension in the jaw and protects teeth from wear.

Treatment is quick, with minimal discomfort and no downtime. Results develop gradually over the following weeks as the muscle activity reduces, improving both facial shape and jaw comfort.

Our clinicians tailor each treatment to your needs, taking into account your dental history, facial structure, and overall goals to ensure safe, natural results.


As with any cosmetic or medical procedure, results vary and all treatments carry potential risks. A full medical history will be taken before treatment, and you may wish to seek a second opinion from an appropriately qualified health practitioner before proceeding.
