Masseter botox is the most comfortable method used in the treatment of teeth clenching habit, which manifests itself with symptoms such as deterioration of the jaw line, pain in the joint head and ear area, wear on the tooth surfaces and tooth sensitivity. The habit of tightening with botox injected into the masseter muscle, which can also be felt in the cheek tissue, can be stopped for about 6 months. At the end of the period, although there is no return in every patient, if the habit starts again, botox can be renewed. The effect of the applied botox starts after 7-10 days, and at the end of this period, the effect of botox is fixed by applying an additional dose.
