So when should amalgam fillings change?
Amalgam fillings should be changed when the integrity of the fillings is compromised, if there are openings on the edges, if there are too many amalgam fillings in the mouth (as the amount of mercury vapor to be released may increase and cause toxic effects), in the presence of diseases whose exact cause cannot be found (to eliminate possible factors), if detoxification is required to for the toxins in the body, replacement of these fillings is recommended.
