Recently, dentists, researchers, and doctors have begun to examine the link between oral health and overall health.
Dental amalgam is a dental filling material used to fill cavities caused by tooth decay. It has been used for more than 150 years in hundreds of millions of patients around the world.
Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. Approximately 50% of dental amalgam is elemental mercury by weight. The chemical properties of elemental mercury allow it to react with and bind together the silver/copper/tin alloy particles to form an amalgam.
Dental amalgam fillings are also known as “silver fillings” because of their silver-like appearance. Despite the name, "silver fillings" do contain elemental mercury. When you visit the dentist, you will be exposed to any of these chemicals: acrylic, formaldehyde, nitrous oxide, phenol, mercury, cadmium and lead. Other toxic exposures can include latex, colorings, flavorings, local anesthetics, and x-rays.
Dental amalgam contains elemental mercury. It releases low levels of mercury in the form of a vapor that can be inhaled and absorbed by the lungs. High levels of mercury vapor exposure are associated with adverse effects in the brain and the kidneys.
FDA has reviewed the best available scientific evidence to determine whether the low levels of mercury vapor associated with dental amalgam fillings are a cause for concern. Based on this evidence, FDA considers dental amalgam fillings safe for adults and children ages 6 and above. The weight of credible scientific evidence reviewed by FDA does not establish an association between dental amalgam use and adverse health effects in the general population. Clinical studies in adults and children ages 6 and above have found no link between dental amalgam fillings and health problems.
Gum disease, also called periodontal disease, is inflammation of the gums. It can lead to the breakdown of the gums, teeth, and bone tissues that hold them in place. Heart disease refers to a broad set of conditions, including heart attack and stroke. Heart disease is caused by the narrowing or blockage of important blood vessels. Many epidemiological studies have investigated the relationship between periodontal disease (PD) and cardiovascular disease (CVD). Oral healthcare professionals can identify patients who are unaware of their risk of developing serious complications as a result of CVD and who are in need of medical intervention.
