Tinnitus

The Mayo is always the best reference. I suffer from tinnitus. Could the disorder you're thinking of be Meniere's disease?
 The dental related cause is TMJ. I was checked for both, mine was caused by a virus.
 

@Mental/@lowrider:
Thanks fellows.  Yes-I did see the Mayo Clinic info.  Don't think it's Menier's disease.  I'm not dizzy and it's in both ears.  On a scale of one to ten, guess it's about a 3-4.  If you've ever been around a gun shot or firework explosion, in close proximity, you know that ringing in your ears that eventually goes away.  I've been around both when young and dumb.  My problem is-it never goes away.  It hasn't interfered with my music listening, but does with multiple conversations going on and some TV dialog.

Me Too !! Sucks just learn to ignore it And live with it 
Good Luck !!

@handymann  have you been examined by an ENT? Ever had a hearing test by an audiologist?
I'm glad I did since they were able to reduce my tinnitus episodes.
