Had one of my teeth removed and ate ibuprofen for that pain. After about a week, I started getting really bad heartburn kind of pain, figured it might be because of the ibuprofen and thought that the pain from the ex-tooth couldn't be as bad as the pain in my chest and throat. So I skipped taking the ibuprofen and in a few hours I was ready to pick up a knife from the drawer and slit my wrists. The pain in where tooth had been was unreal, I was convinced the site had become infected and wasn't sure if I'd be able to wait for the dentist to return my call before killing myself. I was able to hold on long enough to get the call back, was prescribed antibiotics and told to come in the next day, picked the meds up at the pharmacy and took some ibuprofen as well. The next day I was perfectly fine, the dentist didn't find anything problematic in my mouth and so the nightmare scenario must have been a simple result of stopping the pain medication regiment too soon. I learned a couple of things from that bullshit ordeal: 1) ibuprofen is, surprisingly enough, much more effective in killing pain originating in the mouth than opiates are (I'm an addict, so of course my first course of action was to double up my daily dose of my drug of choice, didn't do a damn thing to curb the pain and it was only when I resumed taking ibuprofen that I finally got relief), and 2) dental pain is very effective fuel for suicidal ideation.
