I actually started grinding my teeth (I have stopped now) around when my hearing first started to decline more - I think it was frustration of not being able to hear right and stress with it (new job around that time too but I never grinding before that).
I did get a guard and it helps to relax the jaw because it keeps your mouth slightly open. I only have tinnitus in one ear and i mostly only hear it when I have my aids out - so at night. But I DO notice it is louder in the morning when I wake up. I know that I sometimes clench my teeth when I sleep but I do not think I grind anymore as I haven’t worn the guard for a long time.
Around than when I first developed the tinnitus too but I don’t know if it is because my grinding teeth because well I still have it. I do know that I have an uneven bite because of wrongly done orthodontist procedure when I was a kid (dentist said the reason my bit is misaligned is because they took out too many teeth on top and not on the bottom) so I also have Tmj problems because of this. I often notice if I move my jaw a certain way sometimes that the tinnitus will change.
So I am of the belief that it is jaw than my hearing loss that causes my tinnitus because why don’t I have it in my other ear if it is my hearing loss? My bite tends to set toward the right - tinntuis is in the left ear. My hearing loss is almost equal in both ears as far as I know.
I was also naughty and used a cotton swab because I thought my hearing loss was wax pre_HA so that might have been it too. That is why I went to the ENT - thought there was something in my ear causing the ringing and of course, nothing was there and my ENT dismissed it as part of my hearing loss and that I needed aids.
I still don’t believe that is what is causing the tinnitus and I never will. I have gotten used to mine - I sometimes even sit and listen to it esp. at night when I am going to sleep. Definately takes some psychological adjustment not to tell it drive you crazy! :)
