Expert Answer:
Dental amalgam is a mixture of mercury and a silver–tin alloy.
Adavantages:
- The amalgam filings are strong and long-lasting than other types of filings.
- It is least expensive filling material.
Disadvantages:
- Since it contains the element mercury it liberates very low levels of mercury that can be inhaled.
- Exposure to high levels of mercury vapour are associated with severe effects in the brain and the kidneys.
