What is this? I've brushed my teeth 2-3 times a day since I had a crown/root canal a few months ago, i have throbbing pain throughout my mouth on both side all over, no wisdom teeth removed yet. I'm 21 and pain has been constant for a week or so, getting extremely irritable and it's starting to effect my work, I don't have insurance and can't afford another $3,000 proceedure
