A the dentist some office procedures and drugs could be problematic. Poor dental hygiene at home could result in infections which could cause valve problems. So dental care is important.

Yes: Knowing that you are a heart patient, your dentist may alter the type of local anesthesia he uses. They may decrease or eliminate Epinephrine

Yes...at home!!!!: For many years the american heart association recommended antibiotic coverage prior to dental care. These recommendations have essentially been discarded since there was little proof they worked. However with gum & tooth infections being active infections in the body, daily flossing and brushing plus corrective dentistry will reduce bacteria from entering your bloodstream making you healthier.
