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 misuse antibiotics fuels antibiotic resistance in bacteria, which can inhibit the treatment of antibiotic-resistant infections. Their excessive use in children with otitis media has given rise to a breed of bacteria resistant to antibiotics entirely. Additionally, the use of antimicrobial substances in building materials and personal care products has contributed to a higher percentage of antibiotic resistant bacteria in the indoor environment, where humans spend a large majority of their lives. Widespread use of fluoroquinolones as a first-line antibiotic has led to decreased antibiotic sensitivity, with negative implications for serious bacterial infections such as those associated with cystic fibrosis, where quinolones
