Personal anecdote: removing a lower wisdom tooth that was close to the jaw nerve nearly cured my tinnitus back in the day.

The surgeon dentist was really surprised by this and could not evoke any similar cases in their practice before mine.

It's interesting that worked. It reminds me of Scott Adams' story where he lost his voice due to spasming and got it back through surgery that cut one of the nerves involved.
