Why (specifically) should a dentist care if a patient has a history of heart problems?

Some heart conditions increase the risk of infective endocarditis, an infection of the heart’s inner lining that can occur when bacteria enter the bloodstream. Certain dental procedures can allow bacteria from the mouth to enter the blood, so the dentist needs to review the patient’s history and follow any indicated precautions. A heart history does not automatically mean the dentist cannot provide treatment or must require a waiver; D is the best choice.
