Composite or Tooth-Colored Fillings can be used in some instances instead of amalgam. Tooth-colored fillings are very aesthetic and can at times be unnoticeable. Composite fillings are very technique sensitive and usually require more time to place. Therefore, they are usually more expensive than amalgam fillings.
Remember, there are circumstances in which composite (white fillings) serves better than amalgam; when amalgam is not indicated, or when a more conservative preparation would be beneficial, composite is the recommended restorative material. These situations would include small occlusal restorations, in which amalgam would require the removal of a more sound tooth structure, as well as in “enamel sites beyond the height of contour.”
The American Dental Association Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
