Yes, new changes mean fewer antibiotics needed

Detailed Answer:
Hello and thank you for consulting us on Health Care Magic.
Yes, there has been a change in thinking about this in the last few years. Once we thought that anyone with a murmur was at risk for a heart valve infection called bacterial (or infective) endocarditis when they had invasive procedure like dental work. More recent studies have shown that most patients with a murmur are not at risk. There are some patients that still need antibiotics before dental procedures, these include patients with heart transplants, patients with certain types of valve replacements and patients that have had congenital heart defects repaired. If you are not sure what type of problem you have causing your murmur you could consider having your doctor order an echocardiogram to check that out, but in most problems causing murmurs you do not need antibiotics prior to dental procedures.
