In the past few years, there have been concerns about silver fillers, the so-called amalgams. Because amalgams contain the toxic substance mercury, some people think they are responsible for a variety of diseases, including autism spectrum disorders, Alzheimer's disease and multiple sclerosis.
The American Dental Association (ADA), the FDA, and many public health agencies say that amalgams are safe, and any link between mercury-based fillings and diseases is unfounded. The causes of ASD, Alzheimer's disease and multiple sclerosis remain unknown. In addition, there is no reliable scientific evidence to support the claim that if a person's amalgam filling is removed, he or she will cure these or any other disease.
In March 2002, the FDA reconfirmed the safety of amalgam. Although amalgams contain mercury, they form a stable alloy when mixed with other metals (such as silver, copper, tin, and zinc), and dentists have used it for more than 100 years to fill and save hundreds of millions of rots. the teeth of. The National Institutes of Health conducted several large-scale studies and concluded in 2006 that amalgam fillings are safe.
In addition, there is concern about the release of small amounts of mercury vapor from these fills, but according to ADA, there is no scientific evidence that this small amount of mercury can adversely affect health.
