Only high-risk patients should receive antibiotic prophylaxis before dental procedures to help prevent infective endocarditis. Prophylaxis is reserved for those with conditions that make endocardial infection life-threatening if bacteria enter the bloodstream during dental work, such as prosthetic heart valves, a history of infective endocarditis, certain complex congenital heart diseases, and cardiac transplant recipients with valvular disease. For patients who need prophylaxis and are not allergic to penicillin, the standard regimen is amoxicillin 50 mg/kg (maximum 2 g) given orally 30 to 60 minutes before the procedure. If penicillin allergy is present, clindamycin 600 mg is an acceptable alternative. This approach targets the small group at highest risk while avoiding unnecessary antibiotic use in the broader dental patient population.
