Correct answer: D — Tooth extraction

Dental extraction involves manipulation and disruption of the gingival tissues and periapical region, causing significant transient bacteraemia (oral streptococci entering the bloodstream). This bacteraemia can seed damaged or prosthetic heart valves, potentially causing infective endocarditis. Other high-risk procedures include scaling, root planing, periodontal surgery, implant placement, endodontic surgery, and any procedure involving incision of the oral mucosa. Procedures that do NOT require prophylaxis include: radiographs, orthodontic adjustments, placement of removable prostheses, primary tooth shedding, and lip trauma.
