Infection: Sounds like you have another infection and need a different antibiotic. Get seen soon for treatment. Bacterial infections will not go away on their own, usually, and can get worse if untreated.

Antibiotics only control bacterial infection of tooth for as long as you take them, so corrective dental treatment required (root canal or extraction). Please return to your Dentist for evaluation and appropriate Rx.
