Hi Finn, you're welcome.

personally I would get two amalgams done at one session. The whole procedure with the anaesthetic and all the preparation seems a lot if you're only getting one done at once. Sometimes the best way to get it done is by the dentist numbing on area of the mouth (e.g. lower left side or what side he decides to remove first) and then for him/her to remove the amalgams in that particular quadrant in one session.

It's up to you, I understand how you feel but bear in mind you will already be exposed to mercury vapor in the office itself and the anaesthetic is also not healthy. Wouldn't you prefer to get two or so out in one session? rather than expose yourself to all that, and go through the whole preparation of numbing to just do one?

however, that is your decision and whatever you feel more comfortable with. I do understand your feelings.
