Dental Anesthesia

Medicating for mitral valve prolapse

09/02/2008

Question:

I heard you no longer need to medicate before dental work if you have a mitral valve prolapse. Is this true?

Answer:

Actually, mitral valve prolapse never required Infective Endocarditis (IE) antibiotic prophylaxis. If mitral regurgitation, or leakage of the valve, occurred in conjunction with or without the prolapse, then antibiotics were required.

The newest guidelines determined that the risk of bacterial infection entering the blood stream from the mouth and possibly infecting the mouth was much more likely with daily activities such as tooth brushing, flossing and eating, rather than from dental treatment. Additionally, the decreased use of antibiotics should help reduce resistance to the drugs in the future.
