Amalgam Fillings

Amalgam fillings, also known as silver-colored fillings, are made from a combination of metals such as silver, tin, copper and mercury. The combination of these metals are what give amalgam its renowned strength and durability. Amalgam fillings typically last between 10-15 years compared to composite fillings, which typically last about 5 years. Due to its strength, it is especially used in applications to molars and the back of the mouth, where most of the chewing occurs. Its silver color is also less visible while placed in the back of the mouth, which is usually most desirable for patients. As an added benefit, amalgam fillings are typically more cost effective than composite “tooth colored” fillings.


How it’s done:

First, Dr. Derrick A. Johnston will numb the area of the mouth in which the filling will be placed, followed by a removal of the decayed portion of the tooth. Once this is complete, the tooth is shaped in a specific way to accept the filling and the amalgam is then placed into the tooth. A band may be placed around the tooth at this point to allow the amalgam to condense properly. Lastly, the filling is adjusted and polished to fit your bite comfortably and accurately.


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 in that area for a few hours.
