Yes, if my teeth are misaligned, botox will not fix my bite(if this is what you mean by structural problem). My personal problem is clenching, which is causing me headaches and jaw pain. I have seen a NMD(they said in my case it would not help me), had numerous biteplates, tried muscle relaxers, done 4 months of acupuncture, and nothing has stopped me permanently from clenching. Botox has been proven to stop clenching at least for the time it stays in my body, so how can this not solve anything? They're doing clinical trials on it right now. I've thrown away thousands on things that didn't work so to actually find something that works(stops my clenching), I would pay anything for it.
