Hello Michelle,
I recently finished 39 HBO treatments, like your husband I had a piece of exposed bone and some severe tooth aches. I just finished my treatment on July 11 and they worked like a charm , the exposed bone fell off and healed, had two teeth pulled without any problems. I do now have Myopia and need reading glasses all the time and may even need something stronger, although they tell me it is only a temporary condition it has been close to a month now. I have asked many drs and professionals who work with HBO almost all of them agree that the benefits of HBO are permanent. good luck michelle, e-mail me if you have any other questions.
