Gold has been used in dentistry for nearly 3,000 years. The first book published on dentistry, entitled Artzney Buchlein, appeared in 1530. The book suggests dentists fill cavities and rotten teeth with gold leaf.

Fillings, crowns, bridges, and orthodontic appliances

Thousands of years later gold is still being used for fillings, crowns, bridges and orthodontic appliances. Gold is a bio-compatible metal, meaning it can be placed in contact with a person's body and not cause harm to one's health.

Cell phones

Gold is a highly efficient conductor of electricity and is used in most electronic devices, including cell phones. Gold contained in connectors, switches and relay contacts allows phones to remain free of corrosion.

According to the World Gold Council, a single mobile device contains up to 50 milligrams of gold. That's a tiny amount but nearly 1 billion cell phones are produced each year. With a gold value of about 50 cents in each phone, that adds up to $500 million dollars in gold each year!


Gold can also be found in most standard desktop and laptop computers. The precious metal is used in a CPU's memory chip and motherboard, allowing parts of your computer to receive power and communicate with each other.

A reliable conductor

Gold acts as a reliable conductor, allowing for the rapid and accurate transmission of digital data from one device to another. In fact, only silver and copper are better conductors of electricity.

Healing powers

The earliest medical use of gold can be traced back to China in 2500 BC. Chinese physicians used pure gold to treat furuncles, smallpox, skin ulcers and to remove mercury from skin and flesh, according to GoldBulletin.

Arthritis treatment

Today the metal is primarily used to treat patients with arthritis. Gold salts are used to reduce swelling, bone damage and to relieve joint pain and stiffness. It's a slow process; patients generally receive 22 weeks of gold injections before experiencing relief.

St. Michael's Cathedral in Kiev, Ukraine

Gold is highly malleable and flexible. Gold can be beaten into thin sheets, only a few millionths of an inch thick. These sheets, known as gold leaf, are displayed on buildings throughout the world, such as St. Michael's Cathedral in Kiev, Ukraine.

India's Sripuram Golden Temple

India's Sripuram Golden Temple is the world's largest golden structure. The spiritual park is made out of 1.5 tons of gold. The gold leafing provides a durable and corrosion-resistant covering, according to


It's truly a gold universe. Space vehicles are fitted with gold-coated polyester film to reflect infrared radiation and to help stabilise core temperatures, according to Without gold, darker coloured parts of spacecraft would absorb significant amounts of heat.

Astronaut helmets

NASA also protects its astronauts using gold. Astronauts' helmets are covered by the extravehicular visor assembly. The visor is coated with a thin layer of gold to filter out the sun's harmful rays, according to NASA.
