Mercury intoxication

Mercury intoxication from amalgam fillings: Poisoning caused by tooth brushing and chewing movements due to abrasion of mercury and its compounds. Mercury intoxication of patients with amalgam fillings is repeatedly discussed. According to the latest findings, amalgam fillings are mostly harmless, as the mercury release is far below the daily intake through food. Amalgam is not suitable: for retrograde root fillings, as a material for core build-ups to hold dental crowns or inlays, as a filling material in cast dental crowns. No new amalgam fillings should be placed in occlusal or proximal contact with existing cast restorations. Due to the exposure of the fetus to mercury from the mother's amalgam fillings, no or no further use should be made during pregnancy for reasons of preventive health protection. Alternative materials should be given priority wherever possible. Mercury intoxication is poisoning by mercury or mercury compounds. Possible in dentistry for dentists and staff if the usual precautionary measures are not observed.
