I feel for you... tooth ache really is one of the worst 'not-a-horrific-injury' pains.
I managed to get ear ache a few weeks ago hill walking in strong, cold winds. Don't think I've had ear ache since I was in single figures... surprisingly unpleasant actually which I felt, at the time, was akin to tooth ache. On reflection, perhaps I was being a bit soft... tooth ache I think is worse.
Good luck.
