I used to take an antibiotic premedication before my dental treatment but was recently told it’s no longer necessary. Why?
In 2007, the American Heart Association developed new guidelines that changed which patients were required to have antibiotic prophylaxis prior to dental treatment to prevent infective endocarditis. These guidelines explicitly state that people with mitral valve prolapse (MVP) are not required to premedicate prior to dental work, which is a big change from past thinking on this topic.
