Dental amalgam was the most commonly used filling for cavities in the past 150 years, though its components may shock you.
Silver fillings or amalgam fillings are made of different metals, namely, liquid elemental mercury and a powdered alloy that’s usually a mix of silver, tin, and copper. Thanks to advancements in modern dentistry, there are now better alternatives to filling cavities.
Many are even having amalgam fillings removed for a safer alternative, like resin composites or porcelain. While amalgam fillings have been proven to be durable, affordable, and even outlasting composite fillings, they have disadvantages.
Amalgam fillings don’t match the natural colour of our teeth at all. They’re very noticeable and can even discolour the surrounding teeth. Since they’re made of metals, amalgam fillings do not fare well with too hot or cold food. They can fracture your tooth because the temperature change expands and contracts the filling.
A small percentage of people also can have allergic reactions to an amalgam filling. The apparent reason being, one of its main components is mercury. While studies have found no links between amalgam fillings and health problems, many are still wary about this as an option. As a result, many people choose to remove their amalgam fillings and replace them with composite or porcelain fillings.
