Are amalgam (silver) fillings safe?

According to the CDA (Canadian Dental Association), scientific studies have not verified that dental amalgam is causing illness in the general populations. It is known that amalgam fillings release minute amounts of mercury vapour but this can also be absorbed from natural sources such as foods as well. As a single element mercury is a poisonous metal but in dental amalgam it is bound in an alloy with silver, copper and tin. According to Health Canada they estimate that an average Canadian adult 20-59 years old absorbs about nine millionths of a gram per day with dental amalgam contributing about three millionths of a gram per day. Dental amalgam is still used in dentistry today since scientific evidence shows that there are no significant risks involved with using it where as the benefits to patients are known to be large. As with anything in dentistry there are alternative fillings materials that can be discussed with your dentist if the patient has a concern towards amalgam (silver) fillings.
