Can CLARITHROMYCIN (BIAXIN 500MG) for a tooth/jaw infection? I know you have to be careful what to say or not to say, I just don t have dental insurance, and can t afford to go to the dentist till I get my taxes back, but right now I know I have an infection and I have a full, new prescription, please tell me that it can be used for the infection. Thank you in advance for your time and advice. Chrissie Bergen
