Why didn't bruxism Botox work on me?

Botox can be highly effective as a preventative treatment for teeth grinding. The amount of product required can vary dramatically from patient to patient. Injection of the masseter muscles requires significant knowledge and expertise and I suggest seeing someone who is highly experienced with this procedure.

Botox results vary.  In most instances even for masseter improvement the standard starting dose is 20/30 Units PER SIDE.  In korea they do more. I suggest speaking to an expert.  Best, Dr. Emer.

The experience and the judgment of the injector is critical. Not all doctors know how to treat this. Many patients need very high doses and results will improve if coordinated with a mouth guard during the evening. I am assuming you went to a docotr who uses real botox and not an internet counterfeit product and they knew where to inject? Most people need 3 injection sites per side. I have been doing this for 9 years in this area and have never seen a non-responder.

The proper physician to diagnose TMJ disorders, occlusion and Bruxism is a dentist or oral surgeon which is the only specialist who should be treating such a diagnosis with Botox as this is functional and not "cosmetic Botox" which would be more appropriate for dermatologist or Plastic Surgeon.

Although nothing in medicine is 100% and works all the time this should work.  the type of doctors who treat this vary but you need to be sure you are seeing a board certified dermatologist or plastic surgeon and I have used as much as 100 units on each side
