The dental filling materials are gold, porcelain, composite resin (tooth-colored) and amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
|Gold fillings||Highly visible, specific color|
|Silver fillings||Highly visible, specific dark color|
|Composite resin fillings||Natural tooth color|
|Ceramic fillings||Natural tooth color|
Ceramic fiilings can be chosen according to the tooth color and they resist staining. A ceramic filling can cover a large part of the tooth.
Gold fillings: are made to order in a laboratory and then cemented into place, are well tolerated by gum tissue, for these reasons, many authorities consider gold the best filling material, but it is the most expensive and requires multiple visits.
Silver fillings: are resistant to wear and relatively inexpensive, however, due to the dark color, they are unaesthetic than porcelain or composite and may not be used in visible oral cavity areas, such as front teeth.
Composite resins can be chosen according to the tooth color. The ingredients are mixed and inserted directly into the cavity, where they harden. Composite resins may not be the ideal material for large fillings, because they shrink and can wear out over time.
