Dental amalgam, also referred to as silver fillings, is a common material used for filling cavities and one of the many treatments of restorative dentistry. For the past few years up until now, there have been many concerns raised regarding the use of amalgam as it contains mercury. Mercury is known to be a poisonous substance in any form. Dental amalgam is composed of around 50% liquid mercury, and the remaining half is powdered alloy of silver, copper and tin. Mercury is used for binding alloy particles together so as to form a strong and solid filling.
On the other hand, there are many countries and health and environmental groups who are against the use of mercury as a filling due to its adverse effects on health and environment. According to a health expert, mercury must not be stored above 25 degrees Celsius; however a person’s body temperature is around 37 degrees. Thus, the substance can be easily vaporised from the mouth all the way through the body, particularly if the person is consuming hot foods and smoking cigarettes. Dental practices are also considered one of the major causes of mercury pollution of waterways, affecting the air and environment.
If you are concerned with dental amalgam or know that you are allergic to mercury, discuss with your dentist about other options. Moreover, if you plan to replace your silver fillings, it’s important to talk to your dental team to ensure they know what are the safety protocols for removing and replacing your old dental amalgam fillings.
