Botox for jaw slimming treatment benefits

  • Quick, non-invasive procedure

    Some patients are conscious of having a wide or square jawline. This may be a result of an enlarged masseter muscle, caused by teeth grinding (bruxism) or temporomandibular joint (TMJ) disorders.
    Botox is well-known for its use in aesthetic medicine for gently reducing facial muscle activity to minimise expression lines and wrinkles.
    Botox can also be effectively used to relax the masseter muscle to create a slimmer contour to the jawline. The treatment takes up to 30 minutes and lasts for up to 6 months.

  • Significant results

    A course of targeted botox injections is a gentle, successful way to slim the jawline and achieve a softer, more oval contour.

  • Wider benefits

    Conditions such as teeth grinding (bruxism) or temporomandibular joint (TMJ) disorders can cause an enlarged masseter muscle.
    By relaxing the masseter muscle with botox treatment, tension in the jaw is alleviated. This can reduce the likelihood of bruxism, which can wear the surface of the teeth. In addition, the discomfort of TMJ symptoms can also be reduced.
    When used in combination with botox treatment for the neck, jaw botox has the additional benefit of lifting and tightening the lower face.

The science behind botox
for jaw slimming

Botox, or botulinum toxin, temporarily relaxes muscles through blocking certain nerve signals.

When botox is carefully injected into the masseter muscle, which is one of the primary muscles in the jaw responsible for mastication (chewing), the muscle is gently relaxed.

This reduction in the activity of the masseter muscle results in a slimmer, more oval profile to the jawline.

Botox for jaw slimming has the additional benefits of managing the incidence of teeth grinding (bruxism ***link to treatment page***) and the often uncomfortable symptoms of temporomandibular joint (TMJ***link to treatment page***) disorders

You can be reassured that although injections are being made into your masseter muscle, there is no restriction to mobility or to the function of the jaw.
