Preventive antibiotic administration in oral and dental surgery reduces the risk of serious systemic infections arising from procedure-related bacteremia. Transient bacteremia arises from manipulation of the gingival tissue or the periapical region of teeth and may precipitate complications, such as infective endocarditis, in susceptible individuals. High-risk populations include patients with specific cardiac conditions, selected prosthetic devices, and significant immunocompromise. Most candidates for prophylaxis are asymptomatic and identified through a structured medical risk assessment. Prophylaxis involves administering an appropriate antimicrobial agent before the procedure, in accordance with current evidence-based guidelines, to reduce the risk of bacteremia-associated infection. Indications are limited to defined high-risk scenarios. Contraindications include hypersensitivity reactions, drug interactions, and circumstances in which potential harm outweighs benefit. Clinical challenges include accurate risk stratification, appropriate agent selection, and precise timing of administration. Excessive antibiotic use can lead to adverse drug events and increased antimicrobial resistance, while failing to provide prophylaxis increases the risk of preventable systemic infections. Integration of antimicrobial stewardship principles and interprofessional collaboration is essential to optimizing patient safety and public health outcomes. This activity provides healthcare professionals with the knowledge to identify patients undergoing dental procedures who require prophylaxis and to implement guideline-directed antimicrobial regimens. This activity also provides deeper insights into oral microbiology related to bacteremia, systematic medical evaluation of indications and contraindications, evidence-based prophylaxis protocols, and strategies to prevent unnecessary antimicrobial exposure. In addition, this activity also emphasizes interprofessional collaboration among healthcare providers when caring for patients at risk for procedure-related bacteremia and systemic complications. Objectives: Identify patients who meet criteria for prophylactic antibiotic use prior to dental or oral surgery. Implement guideline-directed, evidence-based prophylactic antibiotic regimens to ensure safe and individualized antibiotic use in dental and oral surgery.

Disruption of the dental mucosa, whether during routine procedures or oral surgery, permits oral microorganisms to enter the bloodstream, resulting in transient bacteremia.[1] This phenomenon has long been recognized as a potential precursor to infective endocarditis and other biofilm-associated infections, including prosthetic joint infections.[2][3] The association between dental procedures and infective endocarditis was first proposed in 1923. By 1935, Streptococcus viridans had been isolated from the blood cultures of 61% of patients with dental sepsis.[4] Recognition of these risks prompted the American Heart Association (AHA) to include recommendations for antimicrobial prophylaxis before dental procedures in its 1955 guidelines.[5] Although antibiotics were historically prescribed broadly in dental practice, contemporary recommendations advocate a more selective approach, limiting prophylaxis to patients at the highest risk of infection.

Appropriate antimicrobial prophylaxis involves coordination across the entire healthcare team, including dentists, oral and orthopedic surgeons, infectious disease specialists, cardiologists, primary care physicians, and pharmacists. Dentists play a central role in the prescribing of antimicrobial prophylaxis. In 2014, a panel of experts developed the ADA guidelines on antibiotic prophylaxis before dental procedures to prevent prosthetic joint infection. Impediments to guideline-adherent prescribing include incomplete information regarding patients’ cardiac histories at the time of dental procedures, pressure from other physicians or patients to prescribe antibiotics, and insufficient education on current recommendations. The current AHA guidelines for infective endocarditis prophylaxis were developed following an exhaustive review of all available data. Cardiologists play a crucial role in advising patients and dentists regarding the need for antimicrobial prophylaxis before dental procedures and oral surgery. Orthopedic surgeons contribute by guiding patients with implanted prosthetic joints. Primary care providers are also involved because patients frequently inquire about prophylaxis prior to dental visits. Infectious disease physicians provide guidance to both patients and other healthcare providers and contribute significantly to education and outreach. Pharmacists assist in antimicrobial selection for complex cases, such as patients with antibiotic allergies, while antimicrobial stewardship pharmacists support appropriate prescribing through outreach and education. Many physicians, surgeons, and pharmacists further advance knowledge on this subject through research. As multiple healthcare professionals are often involved alongside the dentist or oral surgeon, all members of the patient’s care team must deliver consistent guidance and education. Clear and consistent guidance helps prevent antibiotic overprescribing, reduces the risk of antimicrobial resistance, and avoids unnecessary adverse events when prophylaxis provides no benefit.
