Anyone know anything about risk of mercury from filling getting into breast milk? I've done lots of research and seems best to avoid having dental work done but I need a crown as otherwise I will probably end up with an infection and needing an extraction. My baby is 10 months and I want to carry on till 12-13 months. The problem is they have to drill out the old amalgam filling which means I will almost definitely breathe a lot of that in/swallow it. Help!
