Antibiotic use in dentistry of bacteria from advanced caries. The first line of treatment is the removal of the source of inflammation or infection by local operative measures. Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. Penicillin in the form of amoxicillin is the most common antibiotic to use. However, 3% of the patient population is allergic to penicillin, so erythromycin is often used in
Antibiotic sensitivity antibiotic sensitivity testing offered as one combined service. This is because the clinician needs to know which organism is causing the infection, and which drugs will specifically work against this strain.

Because susceptibility can vary even within a species (with some strains being more resistant than others), antibiotic susceptibility testing (AST) is usually carried out to determine which antibiotic will be most successful in treating a bacterial infection in vivo.
