Try not to worry about the stuff written on the internet or in half of the papers, its a load of rubbish. I am a dentist and had to have a filling done last month(naughty, I know) and chose to have it done in amalgam because its a better filling material in back teeth than composite(the tooth-coloured material) Its stronger, tends to last longer and has been used for filling teeth for over a hundred years without incident. Most of our parent's generation have a mouth full of amalgam fillings with no problems whatsoever. If it was as toxic as the Daily Mail would have you believe, that whole generation would have MS, ME, Alzheimers and all the other ailments that are blamed (without proof) on amalgam. Sorry for getting on the soapbox, it just really annoys me the way the media hype things up (see the swine flu for proof) without evidence to back it up and upset members of the public to the point that they wont have the best treatment because they are scared it will make them ill.
The guidance wth regard to using or replacing amalgam fillings in pregnant women is not to do it unless it is an emergency but this is purely precautionary-there is no evidence that it harms the baby. There isnt any guidance for women who are TTC but it would make sense if you are in the 2WW to treat you as though you are pregnant, so I would trly to schedule the appointment for the other 2 weeks of the cycle or possibly put off TTC for a month as although the amalgam is extremely unlikely to cause any harm to the baby if you were to be pregnant, you would probably spend the whole 9 months worrying.
Also, tempting as it may be to leave them as they are not causing you problems, this can lead to needing major work. Its always better to catch things early before the decay spreads, which is why regular check-ups & x-rays are recommended. By the time a lot of teeth show symptoms, the decay can have infected the nerve and you can end up with a root treatment or extraction-much better to have a simple filling.
Hope this helps xx
