Teeth grinding and jaw clenching is a common problem that usually happens during sleep, while concentrating or when stressed. Most people are unaware that they are grinding their teeth or clenching their jaw, but this can lead to common symptoms including headaches, ear pain, pain
and stiffness in the jaw area, wearing of the teeth, and increased tooth sensitivity. Frequent grinding and clenching results in the enlargement of the masseter muscles, the main muscles involved in teeth grinding and clenching.
The masseter muscle is located in the jaw and is used primarily when chewing. An enlarged masseter can be caused by a clenched jaw or teeth grinding through stress, concentration or during sleep. This can cause headaches, pain in the jaw and signs of wear on the teeth (temporomandibular joint disorder or ‘TMJ’). Injecting the masseter can weaken the muscle to relieve these symptoms and visually slim the face.
