Hi there, today is my 9th day taking penicillinV500 x 6hrs for an abscess any time I eat I get like a big pimple red then it gets infected. Need advic?

Antibiotics. Antibiotics will not cure your infected tooth. The infection is spreading to your jaw bone and may become dangerous. You need immediate Dental Treatment. If a Dentist gave you antibiotic and sent you away, find a different Dentist. If you are self-medicating, or got antibiotic from ER, Urgent Care, or Physician, find a Dentist immediately.
