Dental Amalgam

Dental amalgam is a mixture of metals used in dentistry to fill cavities caused by tooth decay. It is comprised of a combination of silver, copper, tin and mercury that is mixed together to create a metal alloy. Although the history of using dental amalgam dates back many centuries, it remains one of the most popular materials used in dentistry today. Due to its longevity and strength, dental amalgam is one of the easiest and most cost-effective ways to repair cavities. It is particularly useful in molars, due to its durability in chewing. Additionally, dental amalgam provides quick and easy repair of cavities, requires less preparation of the tooth, and less time in the dental chair for the patient. While dental amalgam is a safe and cost-effective solution for cavities, there are also some concerns regarding its use. Studies have indicated that mercury, one of the main components of dental amalgam, can be released into the surrounding tissues in the mouth and into the bloodstream of the patient. Depending on the individual’s health and the size of the cavity, this could be a potential source of mercury toxicity. To minimize such a risk, dentists will choose composite filling materials instead of amalgam whenever possible. Composite fillings are composed of glass, quartz and resin, and are far less likely to release chemical compounds into the body. As well, many dental professionals recommend that patients with existing amalgam fillings take extra steps to maintain oral health while reducing exposure to mercury. These steps include eating a balanced diet, brushing and flossing teeth regularly per your dentist's instructions, and scheduling regular dental visits for check-ups. Despite the potential risks, dental amalgam remains an effective and popular solution for tooth decay. When properly maintained, it can last for several years and provides patients with a cost-effective solution for maintaining optimal oral health.
