A dental filling substance called dental amalgam is used to repair cavities brought on by tooth decay

Dental amalgam is a combination of metals made up of powdered silver, tin, and copper alloy and liquid (elemental) mercury. Elements of mercury make up around half (50%) of dental amalgam by weight. The silver, copper, and tin alloy particles can react and bond with the chemical characteristics of elemental mercury to produce an amalgam.

Since of their silver-like appearance, dental amalgam fillings are sometimes referred to as “silver fillings,” however this usage is not advised because it incorrectly describes the ingredients in amalgam. The dentist must first drill the tooth to eliminate decay before shaping the tooth cavity in order to place dental amalgam.

The dentist prepares the tooth cavity for the implantation of the amalgam filling by shaping it after drilling the tooth to remove the decay. The dentist then combines the liquid mercury with the powdered alloy to create amalgam putty under the proper safety precautions. This amalgam putty is moulded and inserted in the cavity after being softened, and it quickly becomes a firm filling. In the event that important new information becomes available, the FDA aims to tell the public.

The advantages of dental amalgam

  • They are sturdy and durable, making them less prone to break than certain other kinds of fillings.
  • Useful for big tooth preparations, individuals with a high risk of dental decay, and situations where moisture makes it impossible for other materials, such resins, to form a connection with the tooth.
  • The least costly kind of filler used in hundreds of millions of people worldwide for more than 150 years.

Dental amalgam may provide risks since it contains elemental mercury.

Releases little amounts of mercury in the form of a vapour that the lungs may breathe in and absorb. High amounts of mercury vapour exposure, which can happen in specific professional situations, have been linked to negative effects on the kidney and the brain.

Young toddlers and foetuses’ developing nervous systems may be especially vulnerable to mercury vapor’s neurotoxic effects.

Regarding the long-term health consequences of expectant mothers, their developing foetuses, children under the age of six, including breastfed babies, there is very little to no clinical evidence available. Parents of children under six and expectant mothers who are worried about the lack of clinical data about long-term health
