Amalgam Fillings
Amalgam fillings, also known as silver-colored fillings, are made from a combination of metals such as tin, copper, silver and mercury. This combination of metals gives amalgam its renowned strength and durability. These fillings usually last between 10 – 15 years compared to composite fillings which typically last about 5 years. Because of its strength, these fillings are particularly used on the molars (back teeth), where the most chewing occurs. Its silver color is also less visible when placed on molars . As an added benefit, amalgam fillings are typically more cost effective than composite fillings (natural teeth shade).
How it’s done
The procedure is done by first removing the decaying portion of the tooth. Once that is complete, the tooth is shaped in a specific way to accept the filling. The amalgam is then placed into the tooth. A band may be placed around your tooth during the process to help the amalgam condense. The filling is then adjusted and polished to fit your bite for maximum comfort.
Additional information
After you’ve had your tooth filled with amalgam, you may experience a temporary period of heightened hot and cold tooth sensitivity. Additionally amalgam fillings do not harden instantaneously, and it’s advisable to avoid chewing on that area for a few hours. Make sure to consult your dentist to understand which type of filling is right for you.
