I have a metallic taste surrounding a tooth with a broken crown, exposing an amalgam underneath. i'm afraid of mercury poisoning and brain damage. what can i do to clean the mercury of my body and reverse brain damage after i go to the dentist?

Your fears are unfounded. You will not be poisoned or detrimentally affected by the exposed amalgam, regardless of what you may have read. Neither will you suffer from brain damage.

I don’t think that you get mercury poisoning and brain damage from the amalgam. Personally, I do not know too many practitioners who use amalgam anymore. Amalgam had been used for many, many years. There are not “millions” of people out there with brain damage. I would not be concerned.
