Q:

What materials are dentures made from?

A:

Modern dentures are typically made out of plastic, often with a metal base, though this may be made out of plastic as well. The plastic of choice for dentures is polymethyl methacrylate acrylic, or PMMA. Historically, dentures have been made out of animal teeth, ivory, porcelain and vulcanite rubber.

Dentures consist of hardened nubs that serve as artificial teeth and a curved plate, or base, that fits against the jaw. In modern dentures, the entire apparatus is often made of acrylic. Dentures with metal bases typically use a chrome/cobalt alloy. Older dentures, including some sported by George Washington, used gold, brass and lead as the base or to secure the dentures to the gums. George Washington's dentures incorporated his own remaining teeth with ivory and did not contain any wood, despite the popular myth.

  • Q:

    Why do teeth turn yellow?

    A:

    Teeth turn yellow because of exposure to materials that cause extrinsic and intrinsic stains. Extrinsic stains occur on the surface of a tooth, while intrinsic stains occur inside the tooth. Most extrinsic stains occur on the enamel and are caused by foods in one's diet. Intrinsic stains, which change the light-transmitting properties of the enamel, are often caused by drugs and other medications.
