question: hi i think i have an infection in one of my wisdom teeth, i think its called pericoronitis? my tooth has been impacted for quite some time but this is the worst it has ever felt as far as pain goes. i do not have insurance at this time to get it pulled or get antibiotics. what i need to know is what antibiotics are used for infections like this,and is there somewhere i can get them without the expensive trip to the doc and an outrageous bill for the help i need?
