You are discussing prevention of infective endocarditis with parents of a child with a complex congenital heart defect. A critical teaching point to emphasize includes:

A. Delaying dental care increases the risk of poor oral hygiene, which can actually increase the risk of endocarditis. B. High-dose IV antibiotics are the treatment for infective endocarditis, not prevention. C. Daily prophylactic antibiotics are not recommended due to risk of resistance and adverse effects. D. Administering antibiotics 1 hour prior to dental procedures is the correct recommendation for preventing infective endocarditis in high-risk children, including those with certain congenital heart defects.
