Masseter pain can be a symptom of temporomandibular joint dysfunction (TMJD) and tension type headaches. Botox into the masseters has been shown to reduce pain levels significantly in these instances.
Between 3 and 4 injections are given into each masseter muscle. The injection may be given while you are clenching hard so that it is directly into the muscle. The muscle can feel a bit sore with clenching for a day or two after treatment. It is possible to return to your normal activities straight away. An anaesthetic is not required.
Results can take 4 to 6 weeks to show. The effect lasts anywhere from between 4 to 10 months.
Botox in the masseter is typically used for:
-managing teeth grinding
-reducing jaw tension, pain, and clenching
-contouring a square jaw
-creating a balanced face shape
