There are two kinds of fillings:
Amalgam Fillings: A mixture of metal consisting of mercury, alloy, silver, tin and copper. They’re more commonly referred to as “silver fillings” due to their appearance. They are strong and long-lasting.
Composite Fillings: Created from a mixture of glass and quartz filler. The main benefit from using composite fillings is that less of the tooth is removed during the procedure than amalgam fillings. They are also tooth-colored instead of silver. Many patients prefer them because they are undetectable in the mouth.
