Many holistic or biologic dentists recommend use of a rubber dam during amalgam removal. The rubber dam is usually a 6×6 square inch sheet of latex, which is held by a clip over the tooth. The dam acts as a barrier, isolating the tooth with the filling to be removed, and preventing debris from getting into the mouth.

We recommend using a rubber dam material that is NOT LATEX due to potential for severe sensitivities or allergic reactions. The most popular material is nitrile.

There is evidence demonstrated by the EPA-approved Jerome mercury detector that the permeability of the rubber dam allows mercury vapors to pass through into the mouth. Therefore, use of the rubber dam may not be as protective as indicated in the literature.
