Bruxism is the medical term for teeth grinding. Most people probably grind and clench their teeth from time to time. It is an oral Para-functional activity. However, if Bruxism occurs on a regular basis the teeth can be damaged. Teeth grinding may be caused by stress and anxiety, it occurs during sleep and represents one of the most common sleep disorders.
Symptoms of Bruxism are:
- Hot, cold, or sweet sensitivity in the teeth
- Earache (the structures of the temporo-mandibular joint are very close to the ear canal, and one can feel the referred pain.
- Sore jaw
Bruxism can change the appearance of your face. In particular, the enlargement of the masseter muscle (one of the four muscles involved in mastication, which closes the jaw during chewing) may lead to a square jaw contour.
Bruxism is successfully treated with Botulinum toxin (type A) injections into the masseter muscle.
It is indicated in two types of conditions:
- a therapeutic indication (to release the symptoms of Bruxism) and
- an aesthetic indication aiming to triangulate and soften the facial contour.
Botulinum toxin injections help to treat the symptoms of Bruxism and reshape the lower face. Relaxation of the masseter muscle reduces muscle hypertrophy and accentuates cheek prominence creating a highly desirable “blush” effect, a more aesthetically pleasant, slimmer, oval-shaped lower face.
Botulinum toxin treatment for bruxism should be repeated every 6 months.
