The most comprehensive comparison between Composite “White” and Amalgam “Silver” Fillings

Several years ago we decided that we would no longer utilize amalgam as a restorative dental material at Dental Dynamics. Our decision was based on several comparative factors between the two materials:

Amalgam - 4

There is no doubt that the current composite fillings are better restorative material than amalgam fillings. Until the recent past, amalgam fillings owned the advantage over composite fillings in terms of durability and longevity. However, the current composite dental materials have better durability, strength and wear than they did in the past making composite fillings much more superior to amalgam fillings.
