Negative effects of massester reduction with Botox?

There is no negative effect long term of injecting masseters with botox.  I suggest you only go to an expert for treatment.  Best, Dr. Emer.

Injection of Botox or other neuromodulators into the masseter muscle can slim the muscle over time improving jawline and reducing teeth grinding in some patients.  There are no long term side-effects, stopping treatment will cause the muscle to rebound fairly quickly.  In the short term, injections can cause irregular smiles and difficulty with chewing if inappropriate placement or dosages are used.  Make sure to seek out an experienced expert injector in your area.

Hi noted your concern regading negative side effects of botox in the masseter if in appropriate placement of the injection occurs it can cause asymmetry while smiling and difficulty in chewing .however when done in the proper plane the likehood of side effects is very low.

An experienced injector can help slim the jawline by injecting Botox into the masseter muscles.  It can also prevent grinding of the teeth.

There are no long term problems. However, there are 2 methods to use to taper the muscle, one uses 5points  and one 2. if the one that uses 5 points there is more injection toward the mouth and you may not be able to have a wide smile.  be sure you see a board certified dermatologist or plastic surgeon

Masseter reduction is a win win situation,   You may be a little weak for awhile but this will go.   Any changes in you voice will soon go.   So no worry.   This is a great treatment.   My Best,   Dr Commons
