Hi, I just went to my dentist because I was having sever pain on one of my wisdom teeth, he said it was infected and either needed to be pulled or root canal. I am on ibuprofen 600mg and penicillin 500mg, and vicodin 500mg all of them every 6 hrs. Ive been taking them for two days now and the pain has gone away but now i have another wisdom tooth on the other side hurting. This tooth hurts sometimes for maybe a day or two then goes away this pain i have now is very little and only hurts when i eat so its not bad like my other tooth. My question is could the infection spread from my left wisdom teeth to my right one? Shouldnt the penicillin kill the infection?
