Materials
In the past, dental fillings and other tooth restorations were made of gold, amalgam and other metals—some of which were veneered with porcelain. Now, dental work can be made entirely of porcelain or composite materials that more closely mimic the appearance of natural tooth structure. These tooth colored materials are bonded to the underlying tooth structure with resin adhesives. Unlike silver fillings (amalgams) they are entirely free of mercury. Many dentists offer procedures to be cosmetic and because their patients prefer natural looking teeth. Cosmetic dentistry has evolved to cover many new procedures and new dental materials are constantly introduced.

Famous quotes containing the word materials:
“If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work”
—C. John Sommerville (20th century)
“If only it were God’s will that printed and written materials have as much influence on the people as the princes and their censors fear! Considering the countless good books we have, the world would have changed for the better a long time ago.”
—Franz Grillparzer (1791–1872)
“In daily life what distinguishes the master is the using those materials he has, instead of looking about for what are more renowned, or what others have used well.”
—Ralph Waldo Emerson (1803–1882)
