Why Do People Bite Gold? The Surprising Answer!

Gold has been a precious metal for centuries, highly valued for its rarity, beauty, and durability. It has been used as currency, for jewelry, and even as a symbol of power and status. Yet, one of the most surprising things that people do with gold is bite it. But why? In this article, we will explore the reasons why people bite gold and the scientific explanation behind this peculiar behavior.

Historical Significance

Historically, biting gold was one of the ways to test its purity. Gold is a soft metal, and biting it leaves a mark. Therefore, if it is mixed with other less precious metals, the teeth marks will be different, indicating lower purity. Goldsmiths in ancient times would often bite gold nuggets or coins to test their authenticity. This method is still used in some cultures today, although modern testing methods have made it unnecessary.

Superstitions and Myths

There have been many superstitions and myths surrounding gold, including the belief that biting gold would reveal its true value or that it would bring good luck. In some cultures, gold was also believed to have healing properties, and biting it was thought to cure various ailments. While there is no scientific evidence to support these claims, they still persist today in some societies.

Marketing Gimmick

In recent years, biting gold has become a marketing gimmick. Some luxury brands have used this idea to promote their products, featuring celebrities or influencers biting gold jewelry in their advertisements. This trend has become popular on social media, with people sharing photos and videos of themselves biting gold as a status symbol or as a part of a challenge.

Psychological Impact

Some people bite gold simply because it feels good. The texture of gold is smooth and cool, and the act of biting into it can create a satisfying sensation. Moreover, the act of biting gold can have a psychological impact. It can create a sense of power or control, especially if it is seen as a luxury item or a symbol of wealth. Biting gold can also be a way of expressing one’s individuality or rebellion against norms and expectations.

Health Risks

While biting gold may seem harmless, there are some health risks associated with this behavior. Gold can contain traces of other metals, such as nickel, which can cause allergic reactions in some people. Moreover, gold is a soft metal and can easily break or crack if bitten too hard, causing damage to teeth. Therefore, it is not recommended to bite gold as a way of testing its authenticity or as a daily habit.

Other Forms Of Gold Testing

There are many other reliable methods of testing gold’s purity that do not involve biting. One of the most common methods is acid testing, in which a small amount of acid is applied to the gold to observe its reaction. Another method is X-ray fluorescence testing, which uses X-rays to analyze the composition of the metal. These methods are more accurate and safer than biting gold, and are recommended for anyone looking to test the authenticity of gold.

Gold Biting Challenges

In recent years, biting gold has become a trend on social media, with people sharing videos of themselves biting gold in various forms, from jewelry to coins. Some of these challenges involve biting through multiple layers of gold or even comparing the teeth marks of different types of gold. However, as mentioned earlier, biting gold can be harmful to teeth and should not be attempted as a frivolous activity.

Why Do People Value Gold?

While the act of biting gold may seem strange and random, it is a reflection of the value that people place on gold as a precious metal. Gold is a symbol of wealth, power, and luxury, and has been used as currency and traded for centuries. It is a finite resource, and its rarity and beauty make it desirable to many people. Despite its practical uses, such as in electronics and medicine, gold continues to hold a special place in human culture and society.

The Science behind Biting Gold

Gold is a soft metal that can be easily shaped and molded, making it ideal for jewelry and other decorative uses. Its malleability also means that it can be easily deformed or damaged, such as from biting. When gold is bitten, the teeth leave a mark or impression on its surface, which can be used to identify the purity or authenticity of the metal. The size and shape of the teeth marks will depend on the force and angle of the bite, as well as the composition of the gold.


In conclusion, biting gold is a unique behavior that has historical, cultural, and psychological roots. Whether it is used as a practical method of testing gold’s purity or as a frivolous social media trend, it is a reflection of the value that people place on gold as a precious metal. However, as we have seen, there are health risks associated with biting gold, and it is not recommended as a reliable or safe testing method. Instead, there are many other well-established testing methods that are more accurate and less harmful.
