According to theNational Institute of Health, amalgam has been widely used in dentistry for the last 150 years due to a combination of low cost, strength, durability, and ease of application.
In general, fillings made out of amalgam are referred to as silver fillings, even though they contain 50% elemental mercury. As mercury has become known for its toxic effects on the human body, many have also started questioning if amalgam fillings are safe.
Read on to find out how safe amalgam fillings are and whether you should have them removed.
With the increase of concerns over the use of mercury in amalgam fillings, several studies were conducted on the safety of their use in dental procedures.
One such study was performed by the U.S. Federal and Drug Administration (FDA) in 2009. It concluded that there are no reasons to limit the use of amalgam as it is safe for use on adults and children over the ages of 6.
Mercury is used in amalgam due to its chemical properties.
To begin with, it helps make the filling more malleable or flexible. When used with an alloy powder composed of tin, copper, and alloy, you get a compound soft enough to be mixed and carefully pressed into a tooth.
Another benefit of using mercury is that it helps harden the filling quickly while also being strong enough to withstand the regular forces of chewing and biting.
There is no reason for you to remove or replace your amalgam filling unless it is broken, worn out, or has decay underneath.
Evidence from various studies points out that amalgam has zero negative impact on people, pregnant women included. In fact, the only time you should steer clear of an amalgam filling is if you have a mercury allergy.
The general consensus around amalgam is that it is cost-effective, flexible, and durable, and hence the perfect solution when you need a filling.
