If both my invislign treatment ($4,000) and tmj treatment ($2,500) fails? I have been 3 months into my invislign treatment and i have yet to see even the slightest results. I also still have significant tmj pain. Is it possible to get most if not all my money back if these treatment fails, i mean my orthodontist highly assured me that these treatments would fix my tmj problem and i feel i have been taking advantage. I am paying a heavy amount of money for results.
