tinnitus can be caused by so many different things....
if your cochlea was damaged by the procedure (mine was) then http://www.**********.*** may has a homeopathic remedy which worked for me. they have about 10 different remedies, all homeopathic.
there is a tinnitus forum here on curezone. there's some great notes on it, particularly in regards some laser treatments which I've been hearing are great. There's one doc in the u.s., and one in Germany. if you can't find the notes on the tinnitus forum, email me.
if the teeth are involved either through infection or bite problems there's a dentist in PA named charles e smith that i've read has had positive results with tinnitus. http://www.icnr.com/cs/cs_14.html
regular doctors don't have a clue about this, don't go there...
