However, research is inadequate to determine the chance of harm occurring and therefore placement and removal should be avoided during pregnancy if possible.

Dental amalgam is thought to be relatively safe to be used as a restorative material as it is used in low doses. Amalgam vapour can be released through chewing but this is minimal.

Therefore, dentists need to instruct patients not to apply undue stress to their freshly placed amalgam fillings. In addition, amalgam restorations are brittle and susceptible to corrosion. The alloys are broadly classified as low-copper (5% or less copper) and high-copper alloys (13% to 30% copper). The solid particles of the alloy are either spherical or irregularly shaped microspheres of various sizes or a combination of the two. The
