Square Shaped Face (Masseter)


The masseters are large muscles, one on each side of the face, connecting the cheek bone to the lower end of the jaw bone. They are used when for chewing food but may be overactive in people who clench their jaws when stressed, grind their teeth or in those that frequently chew gum. These activities can lead to enlargement of these muscles.

Overactivity and associated enlargement of these muscles not only gives a square appearance to the lower face but also can damage the teeth, cause jaw pain and result in temporo-mandibular joint dysfunction (tmj). Neuromodulators such as Botox, Dysport and Xeomin can help reduce muscle tension and overactivity and thereby provide relief.

People with wide jaws may narrow their jaw line by diminishing the size of the masseter muscles with Botox, Xeomin or Dypsort.
