True or False: Silver fillings are also known as amalgam fillings.
True or False: Composite fillings are also known as white fillings.

Answers:

False: Silver fillings do have silver in them, but they are also a mixture of tin, copper and mercury. Mercury makes up nearly 50 percent of the filling and is used to bind all the metals together.
True: Silver fillings are also known as amalgam fillings, or silver amalgam fillings. Amalgam means a mixture or combination.
True: Composite fillings are a mixture of plastic and glass and resemble the color of natural teeth.
True: Metal is the strongest of all fillings. Silver amalgam fillings can last at least 10 years and usually longer.
