NeuroCranial Restructuring

Annyone know if this really work?
I have notcied if i bite hard enough my tinnitus gets louder. I have also some kind of click in my jaw every time i open my mouth (might be tmj).
I did get tinnitus due loud sound exposure, but im startink to think that problem with my jaw/neck might have made my tinnitus worse.
Annyone know if this so called NeuroCranial Restructuring work and if it is safe?
