A 30 years old lady with bruxism habit and dislikes her asymmetrical jawline. She was treated by Botox injection to her masseter muscle. She is very happy with her new look!
The masseter muscle (the large chewing muscles located on the jaw in form of the ears) is a major facial muscle located in the jaw that is associated with chewing and teeth grinding, TMJ or Bruxism. Grinding not only damages the teeth, but some dentists and doctors believe it can also cause headaches and facial pain, known as temporomandibular joint disorder (TMD) or temporomandibular joint pain (TMJ pain).
