Why Antibiotics Can't Cure a Tooth Infection

Video Transcript

Why can't antibiotics cure a tooth infection? Here's the answer. Inside an infected tooth, the pulp is dead. Without living tissue, there is zero blood flow into the root canal. No blood flow means no delivery system for the medicine. Antibiotics travel through the bloodstream. They surround the outside of the tooth root, but they cannot penetrate inside. This creates the illusion of a cure. Pills may temporarily calm the surrounding tissue, but the infection source remains trapped inside. The pain will return. The only way to cure the infection is to physically remove the source. That means root canal therapy — cleaning and sealing the inside of the tooth — or tooth extraction, removing the entire infected tooth. This matches official guidelines. Antibiotics alone are not a treatment for tooth infections. The American Dental Association and American Association of Endodontists advise against relying on antibiotics, because overuse breeds dangerous antibiotic resistance.
