I remember 5 years ago, my symptoms can definitely be connected to metallic braces.

If you must get braces, get plastic ones that are see through.

Yes, they leach plastic in your body, but its better than metal.

and secondly, metals will combine to be more toxic, lead, mercury, etc, metal in frying pans that you breathe in, petrol in the atmosphere, all combine.

Having metal braces was pretty much the very time I can pinpoint when I lost my health. Age 15. They are extremely toxic and in combination with amalgam, it's a nightmare combination.
