One thing to keep in mind is that chelation has a lot of dangers, so be sure to do your research before proceeding with a chelation protocol.
Also if you get your fillings removed, you should do it with someone who can put the plastic tooth colored fillings in, and who are certified in removing mercury fillings. They need a special wall thing and sucker thing to remove them safely (weird tube device similar to what scuba divers use).
If you get the fillings removed, do not do them all at once. This will create a large dose at the same time to your body (so space them out with 1-2 fillings every week or two). Additionally, do not remove them unless they are already damaged. If they are completely sealed and are in perfect condition, not very much mercury will be released into the body. You might have to wait for chelation (this is why I am doing) until they are damaged. Don’t go out of your way to do something that has risks.
