Only the people at greatest risk of bad outcomes from infective endocarditis — an infection of the heart's inner lining or the heart valves — should receive short-term preventive antibiotics before common, routine dental and medical procedures.
The patients who still need preventive antibiotics prior to dental treatment are those with:
- artificial heart valves
- a history of having had IE
- certain congenital (present from birth) heart conditions
- a cardiac transplant which develops a problem in a heart valve.
