There is much controversy concerning silver amalgam dental restorations, or "mercury fillings" as they are commonly called. It is a well-known fact that mercury is a hazardous heavy metal, however when combined with the silver alloy used in fillings, it becomes inert. An analogy would be to consider concrete. The various elements used to make concrete; sand, gravel, water, cement powder, are all free to dissipate if left alone. When mixed together they form a solid, cohesive mass which is insoluble. Likewise, when placed, silver amalgam immediately begins a multistage chemical reaction over the course of several hours, resulting in an inert compound. Thereafter the mercury can only be liberated with intense heat, such as a forge or crucible. Consider, for example, the element chlorine, which is a deadly gas, yet it exists as a compound in the form of common table salt.

The most up-to-date research conducted by the American Dental Association, and other impartial institutions has failed to implicate dental amalgam as a contributing factor in any systemic disease or other pathology. In view of the literally billions of amalgam fillings in existence today, there would be substantial evidence is such a correlation exists.

One of the many virtues of amalgam is its longevity-fillings typically last for decaded, even as long as 50 years or more. The economic benefit of this material is obvious. The years perpetuated by unscientific hearsay are simply unjustified. Nevertheless, it is inevitable that use of amalgam will eventually be discontinued as advances are made in other materials which can provide cosmetic appeal as well as durability. Until then, it's proven track record will ensure that it remains a viable restorative material.
