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:
“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
“Our job is now clear. All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.”
—Lyndon Baines Johnson (1908–1973)
“He was no specialist except in the relation of things.... He took most of his materials at second hand.... But no matter who mined the gold, the image and superscription are his.”
—Woodrow Wilson (1856–1924)
