Antibiotic Prophylaxis in Dentistry: What’s Changed and Why

In this episode of Oral Health Matters, host Dr. Karlynn Sievers is joined by Erinne Kennedy, DMD, MPH, MMSc, Assistant Dean for Curriculum and Integrated Learning at the Kansas City University College of Dental Medicine, for an in-depth discussion on antibiotic prophylaxis in dentistry and why the guidelines continue to evolve. The conversation explores how new evidence has reshaped recommendations by more clearly weighing risks versus benefits, and why antibiotic prophylaxis is now reserved for specific patient populations, including those with certain prosthetic joints, high-risk cardiovascular conditions, and immunocompromising conditions. Dr. Kennedy emphasizes the importance of avoiding antibiotics unless they are truly indicated and introduces the concept of “living guidelines” that are regularly updated as new data emerges. The episode also addresses broader issues of antibiotic resistance, key considerations when treating cardiovascular patients, and the removal of clindamycin from recommended use due to its elevated risk of C. difficile infection. Throughout the discussion, Dr. Kennedy shares practical strategies to help dental professionals implement effective antibiotic stewardship and make evidence-based decisions in everyday practice.   Oral Health Matters is produced by Association Briefings.
