I got Botox for TMJ. Is it possible for the tech to have missed my masseter muscles?

Full effect can take several weeks. If no improvement, a discussion with your treating provider is recommended.

Thank you for your message! I would recommend that you follow up with your provider. It is possible that not enough was injected or the muscles was not injected correctly. Often times, a lot of Botox is required to fully tame TMJ symptoms as the masseter muscle is large. Botox typically takes about 14 days to kick in as well. 

The use of neuromodulator such as Botox can alleviate some symptoms associated with TMJ Disorders.  The medication weakens the muscles that act on the joint.  In other words, it does not directly affect the mechanics of the joint itself.  By relaxing the muscles that surround and move the joint, symptoms can be alleviated.  However, it takes an accurate diagnosis and a proper clinical examination to determine which symptoms are present and why.  It takes several rounds of Botox/Dysport to the muscles of the face that control chewing to adequately relax them prior to feeling relief.  It takes about 1 week for the injection to work, and then it can take up to several weeks to see the benefits with respect to your symptoms.  I tell my patients to wait 1 month following injections before judging the efficacy of the treatment.   However, the diagnosis of TMD (Temporomandibular Joint Disorders) is a complex one.  Not all symptoms can be improved with Botox/Dysport.  I would recommend a proper and thorough evaluation with a Maxillofacial Surgeon to truly assess if you are an ideal candidate for Botox injections to the masseter,  versus injections to additional muscles,  versus a different treatment altogether.   It is possible to miss the muscles or have poor placement, especially when dealing with smaller muscles.  The amount of Botox used for the unique strength of the muscle is also important.  Please consult with a specialist knowledgeable in TMJ and Facial Pain to ensure your time and finances are being properly used.  All the best!
