Can i take amoxicillin for toothache?

Only if it was prescribed by a physician or dentist for a diagnosis of infection within the oral cavity. Please do not take random or old antibiotic scripts without a diagnosis.

Do you have an infection? Antibiotics are not analgesics, and in the end you still need to see a dentist to diagnose your issue and treat the problematic tooth. Don't take medications thinking you will resolve the cause of the pain.
