Two years ago I had a filling fall out of
my very back upper right tooth
but didn't feel any pain or any problems with it, so I sort of just forgot about it. Recently, however, it was causing me pain and I ended up in the ER. I was given antibiotics and a pain killer. I didn't take the antibiotics right away, like I should have, because I went to the dentist the day after and figured he would tell me what to do. I am guessing my tooth was abscessed, though neither places came out and told me.
