  2. I have been in the tinnitus community for a while now and I have experience what you are going though with tinnitus , I do know people that have got
    tinnitus from having their implants done. Ringing in the ear after an implant can go away on its own, but that is BS of what the mouth and jaw specialist said. I have definitely seen and heard of a connection between tinnitus and teeth and mouth. There is a treatment for ringing ears and if you are
    interested you can contact Dr William herbal remedies that what I take that stop the ringing in my ear that was really driving me crazy, don't Lose hope .,I have found a solution for my fellow citizens . If you haven't I would suggest trying Dr William herbal supplement. Again, this is a thing that takes time and usually requires time and patience for it to work WITH no side effects. But I'm not hear to sell you the product, I'm only hear to tell you that it works, but it is a journey and can be difficult. I hope at this point in want away on it own. Good luck . his email address drwilliams098765@gmail.com for advice and for his product
