i had 4 of my 4 Amalgams removed 2 months ago with a high suction vacuum, lots of water and a dental; dam. i have never had any reason to think i had a problem with mercury, i just heard it was a good idea to remove them. i still have one filling, and am planning on keeping it, since it is going to need a crown. my question is, how long do i have to wait to get pregnant. i did a DDI hair test and my results for mercury were 1.4 ug/g.
