Hello.
I've only recently discovered the dangers of amalgam fillings and now I'm desperate to remove mine.
But I live in Kazakhstan and there are no clinics that safely do it. Here no one's even aware of the dangers of amalgam fillings. In neighboring Russia there's also nothing like that.
So I'm thinking about doing what I can, and remove it with a local dentist using a rubber dam. It's better than no protection.
But I also don't have a nasal oxygen mask.
So I'm thinking about making an improvised one, maybe sticking a couple of long tubes into my nostrils and filling my nostrils with something like plasticine around the tubes, so that I can breath though those tubes. Maybe put those tubes out of the window or into some improvised container. Again, it's far from ideal, but it would be better than nothing.

If you have similar experience or have any other suggestions, I'd greatly appreciate them.
